Amino acids are indispensable for healthy skin. They are the building blocks of peptides and proteins and each amino acid performs a specific function in skin care. Some types occur naturally in the skin and work together with aquaporins (the water transport system of your body) to transport moisture through the skin. Some amino acids work as an antioxidant, but most help your skin to reproduce its own antioxidants. Research has shown that synthetic amino acids hydrate better than amino acids originating from an animal or plant source. Whether produced internally or applied topically, amino acids help to strengthen the immune system, maintain the skinís hydration, resilience and an overall healthy appearance. They protect skin from free-radical damage and reduce signs of aging.
The big four amino acids - proline, glycine, leucine and lysine - are the core building blocks for collagen synthesis. Together, they reduce the depth of fine lines and wrinkles while improving moisture retention to soften and smooth your skin.
