L-Serine

Serine is a non-essential amino acid involved in the body’s natural protein synthesis. In skincare, serine plays a key role in moisture retention, helping to improve the skin’s hydration, texture, and overall appearance. It also contributes to maintaining the structural integrity of the skin, promoting a more youthful look. Naturally occurring in the body, serine is considered safe for cosmetic use and is typically formulated alongside ingredients like phospholipids, electrolyte minerals, and components of the skin’s natural moisturizing factor (NMF) to enhance its effectiveness.
