Lysine

Overview

Lysine is one of the essential amino acids that the human body cannot create on its own.

It is used in skincare as a moisturizing humectant ingredient with several additional functions. Lysine is slightly alkaline and can be used as a pH-controlling ingredient (although it is not as popular as arginine due to its often undesirable amine or fishy aroma).
