Science & Benefits

Acetyl Hydroxyproline is an acetylated derivative of the amino acid hydroxyproline, a major component of collagen. This modification enhances its stability and skin penetration. Once absorbed, it signals the skin to accelerate the repair of the extracellular matrix and strengthens the dermal-epidermal junction. As a humectant, it provides deep, water-based hydration. It is completely non-comedogenic and is a high-value active for healing post-acne scarring and maintaining barrier resilience in aging skin that is still prone to breakouts.
