Silk Protein - Smoothness, Hydration, and Protection for Hair and Skin
Silk Protein is an exceptional cosmetic active in the form of silk amino acids obtained through hydrolysis. Due to its low molecular weight, this "liquid silk" ingredient penetrates deeply into the structure of the hair shaft and the surface layers of the skin, offering long-lasting hydration and a high smoothing capacity. It is the ideal ingredient to transform ordinary products into premium treatments, leaving behind a sensation of superior care, natural radiance, and invisible protection.
Ingredients (INCI): Aqua, Silk Amino Acids.
Technical Characteristics

Studied Performance
The manufacturer highlights the unique benefits of silk amino acids for tissue integrity:
- Superior Penetration: Studies show that the amino acids in this product can penetrate the cuticle of damaged hair shafts, strengthening them from the inside, unlike large proteins that only "seal" the exterior.
- Moisture Management: It has an excellent capacity to bind water (hygroscopicity), maintaining optimal hydration levels even in conditions of low humidity.
- Sensory Feel: Provides the skin and hair with a smooth texture, eliminating roughness without leaving a greasy or heavy sensation.
- Protection: Forms a fine protective film that helps prevent dehydration caused by environmental factors or heat treatments.
