Science

Mechanism of Action

PALMITOYL SERINE/SILK AMINO ACIDS METHYL ESTERS functions as a multi-faceted skin conditioning agent. Its silk amino acid components are recognized for their robust ability to bind and retain moisture within the skin, thereby improving hydration levels and promoting a soft, flexible skin texture. These amino acids also actively support the repair of cellular damage and contribute to the skin's natural regeneration cycle. Additionally, they can form a delicate, protective film on the skin's surface, offering defense against environmental aggressors. Serine, a non-essential amino acid integral to this compound, further contributes as a powerful water-binding humectant, playing a critical role in maintaining optimal skin hydration and aiding in the regulation of skin pH.
