摘要
Collagen has been a component of skin care formulations for many years, and over this time, there have been numerous claims of its efficiency. Collagen protein is responsible for firm strong skin, but since collagen fibers are too large to penetrate the stratum corneum (SC), topical creams containing collagen fibers remain on the skin surface without affecting skin quality. To overcome the poor penetration of collagen fibers, we prepared in the past micronized collagen fibers that were proven to reach the epidermis layer while inserted in a cream. In the present paper, we have performed a clinical study that analyzes the effect of the micronized fibrillar collagen containing cream on skin. Fifty five healthy female volunteers were enrolled and completed the study. The anti-ageing, firming, elasticity and moisturization efficacy of the cream were measured using Profilometer, Cutometer and Corneometer respectively. The results showed a significant improvement in skin hydration firmness and elasticity, a significant reduction in fine lines and wrinkles was also observed.
