Silk Amino Acids
실크아미노산
Amino acids derived from silk that can help condition and moisturize the skin.
What does Silk Amino Acids do for skin?
Silk Amino Acids, derived from hydrolyzed silk protein, primarily function on the skin's surface due to their molecular size. They act as humectants, attracting and binding water from the atmosphere to the stratum corneum, thereby increasing skin hydration. Additionally, they form a light, breathable film on the skin, which helps reduce transepidermal water loss (TEWL) and contributes to a smoother skin feel and improved barrier function.
Typical concentration: 0.1-5% (most formulas typically use 0.5-2%)
Is Silk Amino Acids safe?
The CIR Expert Panel has assessed hydrolyzed silk proteins and their derivatives, generally deeming them safe for use in cosmetics. They are considered to have a low potential for irritation and sensitization.
