Amino acids are the building blocks of all living tissue on Earth. These basic building blocks are essential for normal cellular function. Amino acids are the main moisture retention factors in human skin. Topical application of amino acids has shown to dramatically increase moisture content while decreasing visible lines. In addition, amino acids help in the production of collagen and elastin, regulate sebaceous gland activity, decrease discoloration due to sun damage and give the skin a softer smoother feel. In anecdotal reports, topically applied amino acids have helped even difficult skin problems such as dermatitis, psoriasis, eczema, rosacea, acne, stretch marks and other skin care challenges.
