Everything about amino acids in skincare

Proteins are an important component of skin cells, with the two most prevalent ones being collagen and keratin. While collagen alone accounts for 75 percent of skin, keratin is mostly present in the epidermis and is the main component of hair and nails. Collagen and elastin, another protein, are mainly part of the dermis, where both proteins are in charge of maintaining adequate skin elasticity and support. It is within the dermis that wrinkles form.

Adequate supplementation of proteins, whether sourced from animals or vegetables, is essential for maintaining healthy skin and for allowing wounds to heal. Quality proteins and amino acids such as lysine, proline, arginine, and glycine are important for skin maintenance and collagen health and can be found in a variety of dietary sources, including peanuts, walnuts, flaxseeds, chickpeas, quinoa, dairy, egg whites, fish, and poultry.

It is also important to maintain sufficient levels of vitamin C, since it is a co-player involved in in-vivo amino acid production (hydroxyproline). Additionally, it is a valuable antioxidant that plays an important role in preserving collagen and preventing its breakdown.
