What Is Serine?
Serine is an amino acid that is used in the body’s synthesis of proteins. It is considered a non-essential amino acid, meaning that it is produced by the body and doesn’t have to be obtained through diet; however, serine production can diminish somewhat over a person’s lifetime.
As with all amino acids, serine is valuable in skin care because of its ability to help skin retain moisture, giving it a healthier look and feel. It also supports structures in skin that result in a more youthful appearance.
Since serine occurs naturally in the body, it is considered safe as used in cosmetics. It is almost always used in a blend with other ingredients such as phospholipids, electrolyte minerals, and substances found in skin’s natural moisturizing factor (NMF).
