What it is
Dipalmitoyl Hydroxyproline is a lipophilic derivative of the amino acid hydroxyproline, esterified with two palmitic acid chains. This structure makes it oil-compatible and allows it to act as a skin-conditioning and emollient agent in creams, serums, and sunscreens. It is often included in firming and anti-aging style formulas for its conditioning effect on the skin surface.
Safety & warnings
It is generally well tolerated as a conditioning ingredient and is not a recognized fragrance allergen. Because it is a fatty-acid ester, very oil-rich formulas could feel heavy on acne-prone skin, though the ingredient itself is typically used at low levels.
Origin & sourcing
Synthetic derivative made by combining hydroxyproline, an amino acid, with palmitic acid, a fatty acid.
