Description

Dipalmitoyl Hydroxyproline is a lipidated derivative of the amino acid hydroxyproline, where two palmitoyl chains are esterified to the molecule. This chemical modification significantly enhances its lipophilicity and skin affinity, making it a highly effective active ingredient for advanced cosmetic and personal care formulations. It is primarily sought after by manufacturers in the cosmetics, skincare, and pharmaceutical industries for its superior moisturizing and anti-aging properties.

Application

• Anti-Aging Skincare Products: As a key active in serums, creams, and lotions to improve skin elasticity and reduce the appearance of wrinkles.
