Amino acids are the basic building blocks of proteins, which are structural elements of skin cells. They are part of the Natural Moisturizing Factors (NMF), a group of molecules present in the stratum corneum associated in scientific literature with maintaining the skin's natural hydration. NMF includes amino acids, mineral salts, and water-soluble compounds.
In our eye contour care, the presence of amino acids derived from NMF is associated in scientific literature with skin hydration comfort in an area naturally thinner and more prone to tightness sensations.
NMF-type amino acids are also associated in literature with preserving skin comfort. Their documented soothing properties help improve the overall appearance of the eye contour, notably the look of dehydration-related fine lines.
