Biomimetics are among the most exciting and valuable building blocks of scientific research. The interdisciplinary research field of bionics deals with the transfer and development of natural phenomena into optimised technical processes and state-of-the-art formulations. The basis for this are biological, natural processes, which inspire the development of innovative formulations. They imitate (mimic) nature - and harness nature's functions and modes of action that have proven themselves over thousands of years.

For example, the need to store water in different habitats with extreme conditions such as cold or drought has led to creative and sometimes ingenious strategies. Science can make use of these achievements. Thanks to passionate research, it has been possible to understand the genius of nature and use it for human skin - biomimetics such as ectoine, ceramides, squalane, as well as extracts from heather and rye are tailor-made modules for the protection and care of the skin and therefore a supporting pillar of TetCode4.

The active biochemical components of heather extract and numerous polyphenols are produced by the plant itself as a defence against microbes and to protect against UV damage. Due to its antioxidant effect, heather counteracts free radicals and thus also premature skin ageing.

Hyaluronic Acid 

Hyaluronic acid is the key functional substance responsible for maintaining the water balance in the tissues (homeostasis). Hyaluronic acid, which is biotechnologically produced by fermentation, allows the formation of a gel-like matrix that can bind an enormous amount of water and therefore serves as a reservoir. The skin is the body tissue where most hyaluronic acid is found. It contains about 50% of the total hyaluronic acid found in the body of an adult human. 1 gram of hyaluronic acid can bind up to 1 litre of water. As a result, it maintains the elasticity of the skin, smoothes wrinkles caused by dryness and increases the elasticity of the skin's surface. In addition, hyaluronic acid improves the maintenance of the skin barrier and supports regeneration processes of the skin. As a hydro-booster, hyaluronic acid has a positive influence on the overall skin appearance.

Jojoba Oil 

Jojoba oil is extracted from the seeds of the jojoba bush, which is native to the deserts of North and Central America. In terms of its chemical structure, jojoba oil provides a special feature. Unlike other vegetable oils, it is not esterified with glycerine, but with fatty alcohols. Therefore, from a chemical point of view, it is counted among the waxes/wax esters and not among the oils.

An advantage of this "liquid wax" is above all that this wax cannot be split and digested by the skin's own enzymes, which is why it is comparatively long-lasting. In addition, microorganisms that play a role in various dermatological indications cannot metabolise jojoba oil and form possible toxic cleavage products. Due to this property, almost every skin type benefits from jojoba oil, especially people with inflammatory and itchy skin where microorganisms play a role.

Jojoba oil is particularly characterised by the fact that it spreads very well on the skin and is easily absorbed. In addition, it feels pleasant on the skin and, due to its structure, can imitate the skin surface film and thus integrate perfectly. Jojoba oil is very skin caring and makes the skin smooth and supple. It also improves the elasticity of the skin. Jojoba oil contains vitamin E and provitamin A, which gives it antioxidant properties and thus counteracts oxidative stress and premature skin ageing. Due to the many fatty acids it contains, it not only intensively cares for the skin, but it also binds moisture, making it particularly suitable for dry and mature skin. It has also been shown that jojoba oil can have a positive effect on acne, psoriasis and wounds.

Retinol (vitamin A) is a fat-soluble essential vitamin. Retinol and its derivatives (relatives) are used for hyperpigmented, stressed, hyperkeratotic as well as for blemished skin. An important effect of retinol is to increase skin elasticity and smooth wrinkles. Retinol achieves this by inhibiting the breakdown of collagen and promoting its regeneration (anti-ageing effects).

Vitamin A exerts its anti-ageing effects at different levels:

Level 1: Vitamin A's intense antioxidant potential (reduction of oxidative stress) protects connective tissue components from attack by reactive oxygen radicals and matrix metalloproteases (MMPs) by inhibiting them, thus preventing damage to the supporting collagen network.

Level 2: At the same time, it stimulates the regeneration of collagen and elastin fibres, thus having a reorganising effect on the dermal matrix.

Level 3: The stimulation of cell growth leads to horny areas being restored to a normal state. The normalisation of keratinisation through vitamin A thus helps flaky, rough skin to regain suppleness, smoothness and vitality.

Level 4: The cell growth optimised by vitamin A quickly "flushes" pigment accumulations to the skin surface, where they are subsequently removed by the natural exfoliation process. In this way, vitamin A can help to achieve a more even pigmentation of the skin.

In summary, vitamin A reduces oxidative stress and protects collagen. It maintains the skin's elasticity, boosts cell renewal and smooths wrinkles.

Argan oil contains many unsaturated fatty acids and protects the skin from moisture loss. It strengthens skin elasticity, regulates inflammation and has an antioxidant effect. The condition of dry, flaky and irritated skin is significantly improved by argan oil, which makes the skin smooth and supple.

Brassica Campestris

Like many vegetable oils, rapeseed oil is also characterised by a high proportion of polyunsaturated fatty acids. Phytocomplexes based on rapeseed oil are used in cosmetic products as plant emulsifiers and surfactants, which make the skin soft and supple.

Carnauba Wax

Carnauba wax has a film-forming, smoothing and moisturising effect. It protects the skin from moisture loss and gives it natural elasticity. It forms a pleasant protective film on the skin and thus protects it from external influences and dehydration. 

Hydro-genated Castor Oil

Hydrogenated castor oil nourishes the skin and makes it soft and smooth. It also acts as an emulsifier, surfactant and consistency agent. 

Jojoba Oil

Jojoba oil is extracted from the seeds of the jojoba bush, which is native to the deserts of North and Central America. In terms of its chemical structure, jojoba oil provides a special feature. Unlike other vegetable oils, it is not esterified with glycerine, but with fatty alcohols. Therefore, from a chemical point of view, it is counted among the waxes/wax esters and not among the oils.

An advantage of this "liquid wax" is above all that this wax cannot be split and digested by the skin's own enzymes, which is why it is comparatively long-lasting. In addition, microorganisms that play a role in various dermatological indications cannot metabolise jojoba oil and form possible toxic cleavage products. Due to this property, almost every skin type benefits from jojoba oil, especially people with inflammatory and itchy skin where microorganisms play a role.

Jojoba oil is particularly characterised by the fact that it spreads very well on the skin and is easily absorbed. In addition, it feels pleasant on the skin and, due to its structure, can imitate the skin surface film and thus integrate perfectly. Jojoba oil is very skin caring and makes the skin smooth and supple. It also improves the elasticity of the skin. Jojoba oil contains vitamin E and provitamin A, which gives it antioxidant properties and thus counteracts oxidative stress and premature skin ageing. Due to the many fatty acids it contains, it not only intensively cares for the skin, but it also binds moisture, making it particularly suitable for dry and mature skin. It has also been shown that jojoba oil can have a positive effect on acne, psoriasis and wounds.

Carrot Root Extract 

Carrot root extract nourishes the skin and strengthens its antioxidative protective shield. The antioxidant effect can be attributed to flavonoids, which curb free radicals. 

Vegetable
butter and
waxes

Vegetable butter and waxes share the task of forming a protective coating on the skin's surface to protect it from external influences and seal in the skin's natural moisture - just as plants do. Vegetable butter and waxes keep the skin surface supple and elastic and reduce signs of dry and irritated skin. 

Sandalwood Oil 

Sandalwood oil has anti-proliferative, anti-inflammatory and anti-microbial properties. It also has antioxidant properties, counteracting free radicals and premature skin ageing. It is also suitable for use on blemished skin prone to acne. 

Shea butter is the vegetable fat of the shea butter tree. It is particularly skin caring and acts as a consistency provider. Shea butter intensively moisturises and binds so that the skin becomes supple and smooth. This compensates for small defects in the skin barrier, which promotes an intact skin barrier. It is antioxidant, regulates inflammation and thus protects against free radicals and premature skin ageing. 

Soybean
oil 

Soybean oil has a skin-caring and smoothing effect due to its bioactive components lecithin and
α-linolenic acid. Soybean oil protects the skin from moisture loss and thus from dehydration. Due to its inflammation-regulating and antioxidant properties, it protects the skin from oxidative stress and the associated premature ageing of the skin.

Beeswax 

In cosmetic formulations, beeswax serves as an emulsifier, protective film former, natural fragrance, surfactant and excellent active ingredient for the care of transitional mucous membranes such as the lip. It makes the skin smooth, supple and protects against moisture loss.

Biomimetics are among the most exciting and valuable building blocks of scientific research. The interdisciplinary research field of bionics deals with the transfer and development of natural phenomena into optimised technical processes and state-of-the-art formulations. The basis for this are biological, natural processes, which inspire the development of innovative formulations. They imitate (mimic) nature - and harness nature's functions and modes of action that have proven themselves over thousands of years. 

For example, the need to store water in different habitats with extreme conditions such as cold or drought has led to creative and sometimes ingenious strategies. Science can make use of these achievements. Thanks to passionate research, it has been possible to understand the genius of nature and use it for human skin - biomimetics such as ectoine, ceramides, squalane, as well as extracts from heather and rye are tailor-made modules for the protection and care of the skin and therefore a supporting pillar of TetCode4. 

Ceramide  

Ceramides are sphingolipids in which the sphingosine is bound to a fatty acid residue. Along with free fatty acids and cholesterol, ceramides represent the most important lipid fraction of the epidermis and have a very high skin compatibility. As the main component of the barrier in the stratum corneum, they have a skin-caring effect and protect the skin from drying out. The natural skin moisture is thereby preserved and sealed and the skin structure is smoothed.  

Ectoin

Ectoin is a classic example of a biomimetic. It is a strongly water-binding molecule that can form large hydration shells. Therefore, ectoine can stabilise the natural structure of biopolymers such as proteins and biomembranes. It reduces e.g. denaturation processes by making water withdrawal considerably more difficult. Special microorganisms use this property to protect the biomolecules of their cell membranes against heat, freezing, drought and osmotic stress. Ectoin thus stabilises nucleic acids, membranes and proteins. Due to the good moisture binding in the skin, Ectoin has an excellent effect on many physiological parameters in skin. 

Heather Extract 

Heather (Calluna vulgaris) is a rich source of bioactive components whose various properties can have a positive effect on the skin. Due to its chemical composition, the traditional medicinal plant has become the focus of scientific interest over the course of time in order to learn about the diverse benefits on skin health and the bioactive components responsible for them. The active biochemical components of heather extract and numerous polyphenols are produced by the plant itself as a defence against microbes and to protect against UV damage. Due to its antioxidant effect, heather counteracts free radicals and thus also premature skin ageing.

Hyaluronic Acid

Hyaluronic acid is the key functional substance responsible for maintaining the water balance in the tissues (homeostasis). Hyaluronic acid, which is biotechnologically produced by fermentation, allows the formation of a gel-like matrix that can bind an enormous amount of water and therefore serves as a reservoir. The skin is the body tissue where most hyaluronic acid is found. It contains about 50% of the total hyaluronic acid found in the body of an adult human. 1 gram of hyaluronic acid can bind up to 1 litre of water. As a result, it maintains the elasticity of the skin, smoothes wrinkles caused by dryness and increases the elasticity of the skin's surface. In addition, hyaluronic acid improves the maintenance of the skin barrier and supports regeneration processes of the skin. As a hydro-booster, hyaluronic acid has a positive influence on the overall skin appearance.

Lactic Acid 

Lactobacillus Ferment is an active ingredient that is biotechnologically obtained from lactobacilli (lactic acid bacteria) through fermentation processes and is characterised by skin-caring, anti-inflammatory and anti-irritant effects. The hydration of the skin is improved and the pH value and the symbiotic microbial diversity of the skin surface are stabilised. With its positive influence on the complexion, moisture content and microbiome of the skin, Lactobacillus Ferment positively influences skin health on several levels.

Rye Extract  

Rye is a cereal with a very high and balanced nutrient density. Rye is particularly rich in vitamins, trace elements and amino acids. The latter make up a large part of the Natural Moisturising Factor (NMF) in the epidermis and are among the most important moisture-binding active ingredients. Rye seed extract has a clearing and skin-conditioning effect. It acts as an abrasive in cosmetic formulations, which serves to exfoliate old dead skin cells. This promotes the renewal of the epithelium.

Rosemary Extract (Rosmarinus Officinalis Leaf Extract)

Rosemary extract has an antimicrobial and vitalising effect. It also has antioxidant properties and regulates inflammation due to its active compounds. In a study it was also determined that rosemary extract can inhibit UV-induced MMP-1, which is significantly involved in the formation of skin photodamage.

Sunflower Oil (Helianthus Annuus Seed Oil)

The lecithin contained in sunflower seed oil supports the hydrolipid mantle of the skin and has a skin-caring effect, making the skin supple. It also has an antioxidant effect and protects the skin from premature ageing. In addition, alpha-tocopherol is said to protect the skin from UV radiation, especially in the 280-320 nm range. In this way, it prevents damage caused by UV-B free radicals.

Squalan 

Squalane is a saturated derivative of squalene and is extracted from olive oil when used in cosmetics. It is a clear and odourless oil with excellent skin compatibility. Squalene is also a natural component of the sebum of the skin. Squalane nourishes the skin by forming a protective film that supports the skin barrier as another lipid. Squalane is moisturising, softens the skin and is a bioactive antioxidant.
