Palmitoyl proline combines fatty acid palmitic acid with the amino acid proline. It may be synthetic, animal-derived, or plant-derived (Paula’s Choice uses the latter).
On skin, palmitoyl proline acts as a surface treatment by contributing a soft feeling. It also helps cosmetic pigments stay blended in a formula.
The proline component can help shore up skin’s natural supportive elements while the palmitic acid portion prevents moisture loss.
