About
A modified amino acid that boosts skin elasticity and supports collagen production — the kind of ingredient that makes your skin look firmer over time.
Acetyl Hydroxyproline is an acetylated derivative of the amino acid hydroxyproline, a key component of collagen. It functions as a skin-conditioning agent and is valued in anti-aging formulations for its ability to promote collagen synthesis and improve skin firmness. Commonly used at low concentrations (0.1–2%), it is well-tolerated and not associated with significant irritation or sensitization.
