Uric Acid
What is Uric Acid?
Uric acid is a naturally occurring heterocyclic compound found in the body as the end product of purine metabolism, present in human skin at low concentrations. In skincare, it is utilized for its potent antioxidant properties, capable of neutralizing free radicals more effectively than vitamin C or E due to its high redox potential. It helps protect skin cells from oxidative stress caused by UV radiation and environmental pollutants, potentially reducing signs of aging.
Roles in Formulation
This ingredient serves the following purposes in cosmetic formulations:
Skin protecting
Forms a barrier to protect skin from external irritants.
Skin conditioning agent
Maintains skin softness, smoothness, and flexibility.
Soothing
Helps reduce the feeling of discomfort and visible irritation by supporting skin calmness, often through anti-irritant, barrier-supporting, or cooling mechanisms.
Antioxidant
Slows oxidation of oils, fragrances, and sensitive actives to improve shelf life and reduce rancidity or color change; sometimes also supports skin protection from oxidative stress.
