Keratin amino acids, also known as Keratin amino acids, are an essential ingredient in many hair and skin care products. They are a set of amino acids derived from the protein keratin, which is the basic building block of hair, skin and nails. These amino acids have the ability to penetrate the surface layers of the skin and hair, where they help repair damaged structures, moisturize and deliver nutrients.

Keratin amino acids are found in a wide range of cosmetic products, especially those designed for hair. They include shampoos, conditioners, hair masks, but also serums and oils. Thanks to their regenerative properties, keratin amino acids are key ingredients in products for damaged, brittle and dry hair. In addition, they are also integrated into skin and nail care products such as creams, face masks, nail polishes and more. They play a particularly important role in products for mature skin, which needs intensive regeneration and hydration.
