Functional use: Dipalmitoyl hydroxyproline (DPHP) is an anti-wrinkle and firming cosmetic material synthesized from the natural product palmitic acid and the natural amino acid hydroxyproline. The fatty group carried by hydroxyproline effectively enhances the skin's hydroxylation. Proline absorption capacity of proline. After DPHP enters the skin, hydroxyproline is released under the action of lipase. Hydroxyproline is recognized as a collagen-promoting substance. DPHP's quick anti-wrinkle, firming and skin elasticity have been used by a large number of scientific experiments. prove. It is a new anti-aging raw material with outstanding effects.

DPHP stimulates the rearrangement of collagen, shrinks collagen fibers, restores skin firmness, and its activity is significantly stronger than vitamin C. Protecting elastin from enzyme damage, DPHP is more active than vitamin C in inhibiting elastase.

It scavenges oxygen free radicals and has a triple firming effect.

Increases moisture content in the skin, good moisturizing effect
