What is Lysine?
Lysine is an essential amino acid that plays a vital role in protein synthesis and other physiological functions in the body. It cannot be produced by the human body and must be obtained through diet, commonly found in foods like meat, eggs, and legumes.
In lip care products, lysine is used to help maintain skin health and may provide moisturizing benefits. In some cases, lysine is thought to support the healing of cold sores, although the evidence is mixed regarding its effectiveness for this purpose.
