HYDROLYZED OXIDIZED KERATIN.

Insufficient Data CAS - / HAIR CONDITIONING, SKIN CONDITIONING

Hydrolyzed Oxidized Keratin is a refined keratin derivative, engineered with smaller peptide chains to optimize skin penetration. It functions by creating a protective film on the skin's surface, effectively minimizing transepidermal water loss and reinforcing the cutaneous barrier. This action leads to enhanced skin hydration, improved elasticity, and a perceptibly smoother texture.

Humectant Film-former Skin Conditioning Agent Barrier Enhancer

Science

Mechanism of Action

This ingredient actively penetrates the outermost layers of the skin, owing to its precisely hydrolyzed and oxidized structure which yields smaller peptide fragments. Its primary mechanism involves forming a substantive, protective film upon the skin's surface, which significantly reduces transepidermal water loss (TEWL) and thus enhances moisture retention. The inherent amino acid constituents further contribute to skin conditioning, fostering a softer and smoother feel. Furthermore, it acts as a humectant and can strengthen the lipid barrier, thereby augmenting the skin's intrinsic capacity to bind and retain moisture.

Verdict

Insufficient Data

While Hydrolyzed Oxidized Keratin demonstrates a plausible mechanism for enhancing skin hydration and barrier function with an established safety profile, its limited reported current cosmetic use restricts comprehensive direct efficacy data for this specific ingredient.
