Hello sunshine!

As the season changes from winter to spring and then summer, we find ourselves spending more time outdoors enjoying the warm rays of the sun. Hibernation is over, even for the skin. Therefore, it is now important to adapt the protection and care of the skin to the sunny conditions in order to be equipped with an intact skin barrier against long-term sun damage and sun-induced skin aging. Especially during the change of seasons, we advise preventive and regenerative care through and with natural sunscreen. In the following blog article, we provide 4 tips on how to properly prepare your skin for summer while effectively protecting yourself from harmful UV rays.

1. natural sunscreen

Sun worshippers take note: Tanning the skin is allowed and even desired – and without chemical or mineral sunscreen. Because in order to get our vitamin D household going again, it is important to treat yourself and your skin to regular sun again after the often sun-deprived winter – without a sun protection factor. We recommend being in the sun for only a few minutes at first, depending on your skin type. The sun time can then be extended further and further – without overdoing it.

The result: The tan naturally built up by our melanocytes protects against light sunburns up to severe sun damage, as the skin’s own protection time is extended and our body can thus additionally intercept harmful UV rays itself.

2. light protection factor

In addition to or between the phases of tanning, it is important to apply a sunscreen. Even if it does not always seem necessary in moderate spring temperatures, a sun protection factor (SPF) should not be dispensed with as soon as the sun becomes more intense and shines for longer. For this reason, using a skin care product with light sun protection is extremely important, especially in the spring and summer months. Carotenoids, which are found for example in care products with sea buckthorn or astaxanthin, can provide natural light protection. In our store you can find some natural products with sea buckthorn, for example our face serum No.3 and our body oil No.1 or care products with astaxanthin, like our eye essence No.4 or our face serum No.4.

3. reinforced sunshade

Sun protection can and should be additionally absorbed from the inside. Again, it is carotenoids that provide protection from the sun. But foods with antioxidants also have a positive effect against harmful UV rays. If you eat a lot of citrus fruits, berries, nuts, tomatoes or cocoa, you can strengthen the inner sun protection. The dietary supplement with the greatest antioxidant effect is astaxanthin. The carotenoid from the green algae Haematococcus pluvialis reduces the negative effects of excessive UV radiation and can counteract skin-damaging sunburn.

Since the amplification of UV protection via food or dietary supplements only acts as a booster, conventional sun protection should not be dispensed with under any circumstances during long stays in the sun. In this case, we recommend applying a mineral sunscreen after the skin’s own protection time has expired, which immediately blocks the effects of the sun’s rays on the skin.
Caution: The sun-blocker effect also stops the synthesis of vitamin D!

4.effective after sun care

Last but not least, in spring and summer, attention should be paid not only to effective prevention, but also to a valuable follow-up of the skin. After sunbathing, rich and natural care products help to regenerate the skin in the evening. Skin care products with antioxidant ingredients are recommended. A product that also cools the skin slightly, such as our Body Oil No.2, is particularly suitable for after-sun care. As antioxidants help the skin to recover extensively, regenerative care overnight can be used to start a new, sunny day refreshed.

Astaxanthin in skin care

Our skin should be beautiful, firm and healthy. But weather influences, stress and natural aging can damage the skin and leave visible traces. To keep the skin fresh and intact for as long as possible, antioxidants can help beautify the skin’s appearance and keep it healthy. An extremely proven and versatile wonder drug in skin care is astaxanthin. What the natural substance from algae promises and how it can help as an ingredient in natural cosmetics to a smooth skin appearance, we reveal in this blog article.

What is astaxanthin and what can it do?

Astaxanthin is the most powerful natural antioxidant currently known. Research data show that the antioxidant effect of astaxanthin is 10 times stronger than that of beta-carotene and even up to 500 times higher than that of vitamin E. Moreover, it is one of the few antioxidants that cannot have a pro-oxidant effect, i.e. it does not form free radicals itself. It is therefore no wonder that astaxanthin enjoys great popularity.

Unlike other beta-carotenes, it acts as an effective free radical scavenger in intercellular spaces, inside the cell, and throughout the cell membrane. Astaxanthin is therefore not only used in skin care. The natural antioxidant is also very popular for inflammatory diseases, for strengthening the immune system, vision or brain function, and for physical (athletic) endurance (Fig.1).

How is astaxanthin produced?

Astaxanthin is a red pigment found in microalgae and is absorbed through the food chain by crustaceans and fish. It is the reason for the reddish coloration of crustaceans and salmon. Astaxanthin is produced from algae, especially green algae. For human use, astaxanthin is mostly extracted from the blood rain algae(Haematococcus pluvialis), which is known for its high astaxanthin content (Fig.2). Although there is also astaxanthin from synthetic production, the natural astaxanthin from algae is up to 55 times more potent.

Astaxanthin and its effect on the skin

The naturally derived substance brings significant benefits in natural skin care. The best known is the effect of astaxanthin as UV protection and as a natural miracle cure for wrinkles. Thanks to its special molecular structure, it contains both hydrophilic (water-loving) and lipophilic (fat-loving) parts. Due to this fact, astaxanthin is highly fat-soluble and can be used especially well in creams or oils on the skin.

Astaxanthin as natural UV protection – inside and outside

Sun protection is becoming increasingly important these days, because it is now known that there is hardly anything more damaging to the skin than too much UV radiation or even sunburn. Due to its strong antioxidant effect, astaxanthin can be used as a natural sunscreen. While astaxanthin cannot replace the UV filter, it can increase the effectiveness of applied sunscreen products. In addition, astaxanthin reduces the negative effects of excessive UV radiation, helps against the irritation of sensitive skin and soothes the inflammation of the skin caused by sunburn. This protective effect of astaxanthin against damage caused by solar radiation has already been proven by many studies. Astaxanthin thus helps to slow down the development of skin damage and aging of the skin due to UV exposure or to prevent this process.
Of course, the following still applies: only let the sun touch your skin in moderation.

The bottom line is that with the support of astaxanthin – from the inside as well as the outside – your skin won’t be as damaged by the sun and will stay healthier longer.

Astaxanthin as a natural anti-aging agent

Wrinkles are mainly caused by oxidative damage to the skin. These can result from weather influences, such as excessive sunbathing, but also from natural aging or, for example, from smoking or a nutrient-poor, one-sided diet. As a result, the collagen framework in our skin becomes thinner and more fragile, losing the ability to keep our skin elastic and firm. In addition, our body’s ability to produce antioxidants, which it could actually produce itself, decreases with age.

Astaxanthin can prevent this process because it improves the function of mitochondria, which are the energy-producing power centers of our cells, and additionally has a good protective effect on fibroblasts, which are enormously important for the firmness and density of the skin. Thus, astaxanthin can not only protect skin cells from free radicals, but also maintain the natural collagen layer. As a result, astaxanthin has been shown to tighten and smooth the skin for a rejuvenated appearance.

Our tip: Since astaxanthin protects the cell membrane in a way that no other antioxidant can, it shows promising anti-wrinkle effects when taken as a dietary supplement or as an ingredient in applied cosmetics.

Astaxanthin – immune boost for skin and body

Our conclusion: Astaxanthin has not only been proven to increase the moisture content of the skin, but also provides improved skin elasticity. This can reduce fine lines and wrinkles. But the super active ingredient should not be reduced to its contribution to skin health: Astaxanthin is not only a natural UV protector and an effective means against the development of wrinkles, but as a versatile immune boost it is always helpful where our skin or our body needs the support of valuable antioxidants.

Antioxidants

What are antioxidants and how do they work?

Antioxidants are chemical compounds that protect other substances from reacting with oxygen, called oxidation, by preventing or slowing down this reaction. In the process, they react with oxygen themselves and/or intercept oxygen compounds that have an unpaired (single) electron and are therefore very reactive: the free radicals (Fig. 1).1

Fig. 1: The antioxidant (left) donates an electron to the free radical (right), thus neutralizing the free radical and preventing possible cell or tissue damage by the free radical.

Free radicals are produced, among other things, during metabolic processes in the body, but also by cigarette smoke, air pollution and sunlight.2 Ideally, antioxidants and free radicals are in balance. However, if the free radicals in the body are not slowed down sufficiently so that their quantity increases, oxidative stress occurs. If this persists, cell and tissue damage can occur. Based on numerous study data, free radicals and oxidative stress are believed to play a major role in the onset and development of various diseases, such as cancers, cardiovascular diseases, diabetes or allergic diseases.1 By neutralizing free radicals, antioxidants can therefore help to reduce the risk of such diseases.

However, study data also show that under certain conditions – e.g. at very high concentrations – some antioxidants can have the opposite effect and absorb electrons as so-called “pro-oxidants”, which can increase oxidative stress and the risk of developing various diseases.3

What substances are antioxidants and where do they occur?

There are many different substances that can have an antioxidant effect. The best known are vitamin A (retinol), vitamin C, vitamin E (tocopherol), beta-carotene (also known as provitamin A) and other related carotenoids, as well as the trace elements selenium and manganese. Secondary plant substances such as polyphenols, which include the plant pigments flavonoids and anthocyanins, are also antioxidants.
Particularly rich in the antioxidants vitamins A, C and E, as well as carotenoids such as beta-carotene and lycopene, are nuts such as walnuts and pecans, vegetables such as broccoli, peppers and tomatoes, and fruits, especially berries such as amla berries, blueberries/blueberries or sea buckthorn berries (Fig. 2).4

Fig. 2: Berries as a valuable source of various natural antioxidants.

But also spices and herbs such as allspice, cinnamon, mint and oregano are full of valuable ingredients with antioxidant properties.4 Studies now show that some microalgae are also particularly rich in antioxidant ingredients. The focus here is particularly on the chlorophyll of the microalgae Spirulina and Chlorella as well as the carotenoid astaxanthin, which occurs primarily in the blood rain algae(Haematococcus pluvialis). Astaxanthin differs from other antioxidants such as vitamin C, vitamin E and beta-carotene in that it does not develop a pro-oxidant effect due to its unique molecular structure.

What are the health effects of antioxidants?

In a normal concentration and provided there are no contraindications such as drug interactions, antioxidants have numerous positive effects on health. For example, antioxidants such as carotenoids in the diet are thought to reduce the risk of certain cancers and eye disease, and generally to have the ability to strengthen eyes and vision.3, 5

The heart and blood vessels also benefit from the valuable ingredients: they can protect against high blood pressure and reduce the risk of cardiovascular disease.5 Antioxidants also play a major role in the maintenance of cartilage, bones and teeth and ensure the function of tendons and ligaments. Some antioxidants are also known to have antiviral, antibacterial, neuroprotective, or anti-inflammatory effects.5

With regard to the skin, antioxidants promote the synthesis of collagen, which is an essential component of connective tissue, strengthen its structure and intercept free radicals before they can attack the collagen structure. They can also protect the skin from UV damage and are involved in tissue repair and wound healing.5

The special properties of astaxanthin

Astaxanthin is one of the few carotenoids that cannot develop a pro-oxidant effect and is considered the most powerful antioxidant. Comparisons with other antioxidants showed that astaxanthin can neutralize free radicals in the form of excited oxygen molecules, known as singlet oxygen, 6000 times more strongly than vitamin C and 110 times more strongly than vitamin E (Fig. 3).6

Fig. 3: The effect of astaxanthin compared to other antioxidants.

Astaxanthin’s ability to eliminate free radicals is significantly higher than that of other antioxidants: in comparative studies, natural astaxanthin was 14 times more potent than vitamin E, 54 times more potent than beta-carotene, and 65 times more potent than vitamin C.7 Although astaxanthin is still the subject of various studies, its antioxidant and anti-inflammatory effects are already being used as a supplement to conventional medicine for some diseases.8 Due to its anti-inflammatory properties, astaxanthin can be used to repair skin damage as well as alleviate inflammatory skin conditions such as psoriasis and atopic dermatitis.8, 9

Sea buckthorn

The sea buckthorn, also called Hippophae Rhamnoides, is a true powerhouse. That’s why it is often used in cosmetic or skin care products. The active ingredients contained in it can perform small miracles when applied and effectively protect the skin against external influences, such as sun or dryness.

Origin and appearance of sea buckthorn

Sea buckthorn is widespread in Central Asia. However, the sea buckthorn bush grows everywhere in the temperate maritime or continental climate – preferably on slightly moist, dry and calcareous sandy soils in the upper layers or on clay and clay soils. The plant also thrives particularly well on river banks, sea coasts and dunes.

Depending on the location, the sea buckthorn is a very annoying, thorny, willow-like shrub of 1–3.5 m in height. The strongly branched, rather upright sea buckthorn tree can reach a height of up to over 6 m. The uneven and bulky protruding branches have a smooth, dark reddish-brown bark. The fruits are bright orange-red, spherical pseudo-berries.

Sea buckthorn oils and their special features

The oil of sea buckthorn is divided into three different types of oil depending on the method of extraction:

  • Pulp oil
  • Pumpkin seed oil
  • Pomace oil

The three types of oil of sea buckthorn differ significantly in their active ingredient content and in the fatty acid composition. A special feature of orange-red pulp oil is the high content of palmitoleic acid (about 35%), which is only present in very small quantities in other plants. Palmitoleic acid is a component of skin fat, which is why sea buckthorn pulp oil is particularly suitable for regeneration and care of heavily stressed skin. In addition, it contains valuable so-called unsabarable components with a high content of sterols, carotenoids and tocopherols as well as simple and essential fatty acids (e.B omega-3 fatty acids). In addition, all fat-soluble vitamins are found in this oil – especially vitamins A and E, but also vitamins C, B1, B2, B3 and B9 as well as 14 trace elements and various minerals. The natural vitamin E content helps protect cells from oxidative stress.

Sea buckthorn pulp oil – CO2 extraction

The most active ingredient of these oils is sea buckthorn pulp oil. It is obtained by cold pressing, centrifugation or extraction with supercritical CO2. CO2 extracts are carriers of the strongest biological activity. This makes them particularly indispensable in the development of effective cosmetic and pharmaceutical products. In addition, CO2 extracts have a lipophilic (= fat-loving) character. This allows the molecules of the biological active substances contained in the extract to penetrate more easily into the deeper layers of the skin and thus unfold their effect.

In the production of CO2 extracts, natural carbon dioxide (= CO2) is used as a solvent for the extract. Under very high pressure, the gaseous CO2 is compressed so strongly that it becomes liquid and flows through the plant material. In this way, the fragrances and active ingredients are dissolved without leaving solvents or other residues of inorganic salts, heavy metals or reproducible germs.

As soon as the pressure decreases, the CO2 becomes gaseous again and can be recycled for the next extraction process. What remains is a high-quality, pure and residue-free extract of the plant.

It is exciting that the yield of sea buckthorn pulp oil by CO2 extraction is 12.5% higher than by the other extraction methods.

Effect of sea buckthorn

Sea buckthorn has a regenerating and anti-inflammatory effect. Therefore, the fruit is also often used in care products for irritated, dry skin but also for impure skin. Sea buckthorn can also be used in the treatment of skin diseases such as acne or neurodermatitis.

Sea buckthorn nourishes the skin intensively, tightens the tissue and supports the skin’s own protective barrier. The high-quality sea buckthorn pulp oil is used as a preventive measure against wrinkles and pigmentation disorders as well as for allergic, sensitive and itchy skin.

Thanks to its high beta-carotene content, sea buckthorn provides natural sun protection and protects against the influences of free radicals. It is often used externally as a prophylaxis and therapy for and against radiation damage to the skin (e.B. burns, sunburn, X-rays, etc.). Sea buckthorn is therefore found in sun protection products and products for the relief of sunburn.

Facial oil or face cream

Did you know that water can dry out your skin and moisturizing creams almost always contain water (aqua) as the largest proportion?

But how can it be that products do the exact opposite of what they promise?

The answer is quickly given: water causes the cells in the uppermost layer of the skin to swell and washes out the fats between the skin cells as well as the moisture-binding substances. As a result, the skin can gradually dry out; a feeling of tension arises. To relieve this feeling, a cream is often applied. This is quickly absorbed, as the moisture contained is absorbed by the skin like a sponge. The active ingredients such as vitamin C in creams are transported into the skin, but at the latest at the next cleansing the vicious circle begins again. The result is that the cream has to be applied daily – often even several times – and it comes to a dependency. The skin has forgotten to regulate the moisture balance itself due to the loss of the intact, protective water-fat barrier.

Face cream

Each face cream is a mixture of water and fat. Emulsifiers are used to bond these immiscible liquids together. These excipients are usually synthetically produced and thus foreign to the skin.

Face creams are often based on a variety of ingredients, which sound incomprehensible to most users on closer inspection. These often include mineral oils, preservatives and hormonally active substances that can have negative effects. Mineral oils are foreign to our body. They remain in the uppermost layers of the skin and create a film there that seals the skin. As a result, it can no longer breathe properly and regeneration processes of the skin are slowed down or even prevented. Since mineral oils do not penetrate deep into the skin, they are also not suitable for transporting active ingredients, antioxidants and vitamins into the deeper layers of the skin.

The goal of good care products should be to keep the natural skin barrier intact or to regenerate the damaged protective vision of the skin. The active ingredients required for this are to be transported exactly where they can unfold their effects.

Our facial oils consist of carefully selected, exclusively natural and gently processed oils and extracts, all of which come from controlled organic cultivation or from wild collection.

Facial oil for every skin type

Oils have different properties and care effects for the skin due to their individual components. Due to the specific combination of oils, there is the right facial oil for every skin type. However, this should always be tailored to the current needs of the skin.

Normal skin

Normal skin shows no or only small deficits and therefore requires a care product that keeps the skin barrier intact and protects. This protection is important to keep the skin resistant. It should be able to defend itself against externally harmful influences, which are often also triggers for later skin problems.

Dry skin

Dry skin longs for appropriate fats, which it can retain in the skin, as well as for an intact skin barrier.

But why is the skin dry?

As is probably often experienced on one’s own body, water can dry out our skin – as with long bathing or frequent hand washing. This happens mainly because the skin’s own fats are dissolved out. Especially in combination with soaps that contain surfactants or saponins, this happens much faster. After all, removing dirt and grease is the job of a soap. The disadvantage, however, is the removal of the important skin fat and the destruction of the natural skin barrier.

Now, by washing or cleansing the facial skin, the important fat is released from the skin and then usually a face cream is applied. Although this cream – an emulsion of water and fat – moisturizes for a short time, it has the opposite effect in the long run: the skin dries out further and further, the skin barrier is destroyed.

For dry skin, the following points are particularly important:

  • Suitable fats must be offered to the skin so that the fat layer can be rebuilt.
  • The natural skin barrier must be regenerated and intact so that the skin fats can be kept back in the skin.

It is precisely these functions that a facial oil for dry skin must fulfil.

Facial oil for dry skin

Dry skin tolerates – especially at the beginning of the application – a “moisturizing” facial oil. Moisturizing are e.B oils that contain a high proportion of oleic acid. Examples include marula oil, apricot kernel oil or olive oil.

With the application of a single moisturizing oil, however, the same effect as with the appropriate combination of oils and active ingredients will never be achieved. A specific composition is therefore important in order to transport the substances exactly where they are supposed to work in order to rebuild the skin barrier.

Once the natural protective layer of the facial skin has been regenerated, you can switch to a care product for normal skin. It is then important to keep the skin barrier intact.

Oil also for impure oily skin?

Admittedly, it sounds paradoxical, but it is not. Certain oils contain sebum-regulating ingredients. These signal to the skin that it can reduce its sebum production. Oils rich in linoleic acid are ideal for impure and oily skin. Such oils are, for example, Kalahari melon oil, argan oil, grape seed oil or hemp seed oil. They can – again in the appropriate combination with other oils – penetrate deep into the skin and thus unfold their effect. Often oils with a lot of linoleic acid also contain a high proportion of vitamin E. This vitamin is a powerful antioxidant and is often referred to as the “Anti Aging Vitamin”. It can have an anti-inflammatory effect as well as promote cell renewal. Skin impurities and inflammation can thus be alleviated.

Comedogenic oils

People whose skin is prone to impurities should avoid comedogenic oils. These oils have a high content of oleic acid, which can clog the pores of the skin. Examples of comedogenic oils include coconut oil, olive oil, wheat germ oil, palm oil, apricot kernel oil, marula oil, and avocado oil. These oils are suitable in facial oils for dry skin, but not recommended for skin with impurities.

The use of the right facial oil for the appropriate skin type is therefore very important.

Sensitive skin

For care products for sensitive skin, care should be taken to ensure that the proportion of essential oils is not too high or that there are no essential oils at all. Essential oils contain allergens to which sensitive skin can react with allergic reactions and skin irritation.

Mature skin

Mature skin often lacks elasticity and moisture or skin fat. In particular, oils from seeds and nuts of plants are very well suited for mature skin, as they usually resemble the skin’s own fat very similar. External influences can accelerate skin aging. Therefore, light-protecting ingredients and antioxidants should also be incorporated into facial oils for mature skin. The most powerful antioxidant known is natural astaxanthin. It is a carotenoid from an algae, which has the property of both catching free radicals and having a light-protecting effect.

Facial oil for the winter

Normally, the uppermost layer of an intact skin has a moisture content of up to 40%. In winter, however, this moisture content can drop to less than 10% due to weather conditions and dry heating air. As a result, the skin’s natural protective barrier becomes permeable and external influences can penetrate the skin more easily. The skin is then exposed to cold, frost, snow, icy wind, UV light and pollutants almost defenseless. Sub-zero temperatures also cause the blood vessels under the skin to contract in order to preserve the heat inside. The skin is less supplied with blood and less oxygen and nutrients. Already from about 8 degrees Celsius, the sebaceous glands reduce the production of protective skin fat.

The result of this is often cracked, brittle and itching-prone skin, usually associated with feelings of tension and dandruff.

UV radiation is particularly high in winter because it is reflected by snow and ice.

In winter, we should therefore particularly support the natural protective layer of our skin. Therefore, it is advisable to use fat- or oil-based care products and not water-oil emulsions such as creams.

The use of face creams can cause frostbite on the skin at sub-zero temperatures, as the water molecules they contain can freeze.

Special needs of the lips

Lips do not have their own sebaceous and sweat glands and therefore cannot produce a protective greasy film. Therefore, they become slightly cracked and brittle, especially in winter. Our lips are also very sensitive to UV radiation. With a lip care that contains high-quality fats and a light sun protection, the lips are optimally protected and remain supple.

Skin and nutrition

In addition to the appropriate care, our diet is also crucial for healthy skin. This provides the building blocks for the renewal of the cells from the inside. The outer layer of the skin, also called the epidermis, completely renews itself within about 30 days. The appropriate diet is therefore particularly important with regard to the skin for the prevention of skin diseases such as neurodermatitis, psoriasis, acne, etc., but also as a therapy.

Kalahari melons from Namibia

The Kalahari melon is exceptional. The oil pressed from their seeds has a unique composition of fatty acids. Combined with one of the strongest known antioxidants and high-quality vitamins, kalahari melon oil is a precious, still unknown treasure for natural cosmetics and skin care products.

Wild watermelon or tsamma

The Kalahari melon is also called “Wild Watermelon” or “Tsamma” by the locals. It grows mainly on the dry soil of the Kalahari Desert in Namibia and Botswana, from where it got its name. It grows over the desert floor and bears yellow flowers. The ripe flesh is light and slightly bitter in taste.

For the indigenous peoples of the Kalahari Desert, the Tsamma is an important source of water and food. The seeds of the Kalahari melon are often dried, roasted and ground into flour or the oil is extracted from the seeds.

Kalahari Melon Oil for PHYSTINE

The Kalahari melons for PHYSTINE are harvested by women of the Sivara village community in northern Namibia. The cores are then used by Olli Rust and his team gently cold pressed for us. The golden yellow oil is filtered several times until there is no dust from the pressing process. The crushed shells of the seeds, the so-called press cake, which remains during oil extraction, are used, among other things, in the baking of bread.

Special features of seed oil

The Kalahari Melon Oil (Citrullus Lantus Seed Oil) impresses with its extraordinary fatty acid spectrum. It contains a very high proportion of linoleic acid, an unsaturated omega-6 fatty acid. This is particularly important for the human body for two main reasons: On the one hand, linoleic acid cannot be produced by the body itself. On the other hand, ceramide I, an important component of the uppermost layer of the skin (stratum corneum), which is the skin’s natural barrier, is formed from linoleic acid. If too little of the essential omega-6 fatty acid is absorbed, this often leads to disorders of the skin barrier, dry and flaky skin or other skin problems.

Not only the high proportion of linoleic acid in Kalahari melon oil, but also the presence of the carotenoid called lycopene makes the gold-colored oil so effective. Lycopene is one of the strongest known antioxidants that can trap free radicals in the body and skin. As a result, it counteracts the signs of skin aging and is ideal in anti-aging care products.

In addition to the already mentioned special features, the seed oil of the Kalahari melon also contains high-quality vitamins such as vitamins A, C, E and various B vitamins – a true elixir for the skin!

In order for Kalahari Melon Oil to unfold its unique effect, we always combine it with other specifically selected oils or substances, depending on the effect we want to achieve with our care product.

The appropriate mixture of oils and ingredients is our key to transporting the highly effective active ingredients exactly where they are supposed to work.

The oil of kalahari melon is not comedogenic due to the low proportion of oleic acid, which means that it does not clog the pores of the skin and is also quickly absorbed.
