Amino Acids

871 results

Amino acids are proteins essential to lasting skin health. There are different kinds of amino acids, each with their own unique function but above anything else, they're known for their anti-aging abilities. 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.

When incorporated into face serums, creams and treatments, you receive essential anti-aging benefits coupled with hydration and antioxidant defenses. In fact, amino acids are so essential to healthy skin, they're known to not only protect your skin from UV damage but actually repair the damaged tissue. When your body becomes amino acid deficient, you're unable to synthesize protein, meaning the collagen and elastin that keep your skin soft, smooth and supple are depleted.

So stock up on professional-strength brands like SkinCeuticals, SkinMedica and PCA Skin along with others to discover the difference amino acids can make.
