Palmitoyl pentapeptide is a fatty amino acid that boosts the production of collagen in skin. It’s also highly absorbable, which makes it an ideal ingredient in many anti-aging formulas that target fine lines and wrinkles. It also stimulates the production of hyaluronic acid which is important for skin hydration. In short, producing new collagen and improving the skin’s moisture levels are two of the most important criteria in effective anti-aging formulas. Studies have also shown that it is as effective as retinol, but has fewer irritating side effects. As an ingredient, palmitoyl pentapeptide hits a home run with dermatologists: a non-irritating treatment that reduces wrinkles, improves skin tone, skin elasticity and overall skin health.
