WHAT IS SILK PROTEIN?
Silk protein is the amino acid complex that is derived from the silkworm’s cocoon. The protein, which constitutes the foundation of life, is an important food source and has important functions in the medical and cosmetic field. In relation to all protein types used for this purpose, the structure of silk molecular weight and water soluble glycoproteins called "fibroin" and "sericin" Silk protein is used quite a lot in skin and hair cosmetics.
When silk protein is used in cream or lotion form, it increases skin elasticity, reduces wrinkles and has an anti-ageing effect.
Silk protein protects the balance of moisture while preventing moisture loss from the skin.
Silk protein forms a protective film on the surface of the skin.
Silk protein adds softeness and smoothness to the skin.
Resistant to washing.
Removes colour distortions on the skin.
Repairs molecular deformations related to sun exposure.
Gives silky softness.
Silkworm cocoons, which have been used for beauty purposes in the Far East for centuries, have been used in cosmetics in different forms with developing technology. Therasilk researchers have developed appropriate formulations with the most effective forms of silk peptides in more than 10 years of R&D and innovation studies. Various evaluations have been made in both dermocosmetic and medical fields.
Therasilk products are pioneers in this field and by using silk, a valuable material, and by carefully maintaining its purity, Therasilk develops product formulations with the same precision. The Therasilk brand has worked for more than 10 years on its formulations to combine the efficiency of silk together in harmony with other cosmeceuticals and standardised the most effective way of use and dosage for the skin.
WHAT ARE COSMECEUTICALS?
Cosmeceuticals are products with biologically active components that are effective in skin care. They are products that intend to improve skin health and repair damage caused by specific skin conditions and ageing such as fine lines, wrinkles, laxity and hyperpigmentation. These products provide a bridge between prescription-based products and over-the-counter cosmetics, and their effectiveness is supported by science
Silk protein, the benefits of which are revealed in the light of many scientific studies, with its purity and natural quality, it is a gift from nature that we can safely use for our baby.

SILK IS NATURAL KERATIN
According to historical sources, the fact that since ancient times the Japanese women who worked with silkworms and in the production of silk yarn always had youthful looking hands is noteworthy. The Far Eastern women who discovered the effect of silk on skin health have used silk for cosmetic purposes since ancient times
Silk protein is obtained by processing the silk from the silkworm. Our skin and hair is made of keratin which has the same structure as silk.
5 BENEFITS OF SILK ON THE SKIN
Silk molecules absorb 10 thousand times more water than their own mass and with their porous structure they remove excess liquid from their surroundings, maintaining ideal moisture for the skin
Natural antı-wrınkle effect
It is very similar to collagen fibers with a rich amino acid content. It tightens the skin and prevents wrinkles through keratinocytes on the skin, both by maintaining the moisture balance and cellular metabolism
Colour differences on the skin are caused by irregular melanin accumulation as a result of oxidation of tyrosinase. The serine amino acid in silk protein prevents this enzyme activity.
UV BLOCKING EFFECT
It provides protection by absorbing the sun’s rays, which is one of the most important ageing factors for the skin.
The thin film formed on keratin tissue protects the skin from external effects and soothes existing sensitivity.

THE USE OF SILK PROTEIN IN COSMETICS
Silk proteins by nature are similar in structure to human skin and hair. In this respect, silk proteins that tend to keratin tissue show their functions through keratinocyte cells. The dermis layer cells that make up the top layer of our skin are keratinocytes. Our skin wears out and ages due to biological causes and damage caused by sun rays. Silk proteins have the ability to absorb the sun’s rays perfectly and are capable of preventing cellular DNA damage caused by these harmful rays and resists oxidation occuring.
Negative environmental conditions and genetic factors over time cause increased numbers of melanocyte cells in the epidermis and localised irregular pigmentation. As a consequence of the keratinocytes’ effort to protect the cell’s nucleus against UV rays, the skin loses its shine and dark patches begin. Silk proteins protect the cells from UV rays like armor by adhering to keratin tissue and covering it like a film. The skin then regains a bright and vivid appearance.
While our body contains 70% water, 20% of the total water is in our skin. With the compelling effect of external factors, fluid loss and insufficiency causes increased wrinkles. The keratin layer that forms the upper layer of the skin forms a barrier to prevent water loss.
Silk proteins maintain the moisture balance while repairing the integrity of the keratin layer which is disrupted due to many different reasons such as; soap, UV rays, wind etc. during the day. Silk provides the optimum moisture requirements.
The silk protein sericin has a strong UV protective feature
The product formulation provides an ideal diffusion opportunity.
Prevents DNA damage by inhibiting lipid peroxidase and tyrosine kinase enzyme activities, activating repair mechanisms.
It has the capacity to hold water up to 10,000 times its own structure.
Polar side chains consisting of low molecular structure and carboxyl and hydroxyl and amino groups, provide easy cross-linking, copolymerisation and blending with natural and synthetic polymers.
