Dipalmitoyl Hydroxyproline

What Dipalmitoyl Hydroxyproline is & what it does

Dipalmitoyl Hydroxyproline is an amino acid derivative in which hydroxyproline, a building block found in collagen, is linked to two palmitic (fatty) acid chains. In skincare it is used as a skin-conditioning and antioxidant-type ingredient, often included in firming or anti-aging style formulas. The fatty chains make it lipid-soluble and easy to incorporate into oil phases.

Dipalmitoyl Hydroxyproline is used in cosmetics as a conditioning ingredient and is generally considered well tolerated at normal use levels. It is a lipid-soluble amino acid derivative rather than a strong active. People with sensitive skin can patch test a product that contains it before fuller use.

Is Dipalmitoyl Hydroxyproline vegan?

Dipalmitoyl Hydroxyproline can be made using palmitic acid that comes from either plant or animal sources, so its vegan status depends on the manufacturer. Many cosmetic suppliers use plant-derived fatty acids, but this is not guaranteed. A strict vegan should confirm the source with the brand.
