Histidine HCl

Description

Histidine HCl is a form of the amino acid histidine, stabilized with hydrochloric acid for better solubility in water. In cosmetics, it is used as an antioxidant, soothing agent, and pH regulator. Histidine plays a role in protecting skin cells from oxidative stress, strengthening the skin barrier, and helping to reduce irritation. It can also bind heavy metals and neutralize their effects, so it is often added to products for sensitive or damaged skin, as well as anti-aging and sun protection products.
