• L-Serine



L-Serine also known as β-hydroxyalanine, is a neutral aliphatic amino acid containing hydroxyl groups [4]. Serine is a neutral aliphatic hydroxy amino acid, a non-essential amino acid, chemical formula C3H7NO3, molecular weight 105.09, melting point 496~501 K, easily soluble in water, almost insoluble in non-polar solvents. Serine can be used as an additive for skin nutrition; serine has hydroxyl groups, so it is one of the amino acids with strong moisturizing ability, and it is often used as a moisturizing agent for skin. It can be made into liposomes with phospholipids, and then combined with other active ingredients for better moisturizing effect; serine can promote hair growth and reduce hair loss.
