Tranexamic Acid
What is Tranexamic Acid?
Tranexamic acid is a synthetic derivative of the amino acid lysine, originally developed for medical applications but now incorporated into skincare formulations. Chemically, it is trans-4-(aminomethyl)cyclohexanecarboxylic acid, functioning primarily in cosmetic products as an astringent and skin conditioning agent. As an astringent, it temporarily tightens the skin's surface by interacting with proteins, which helps minimize the appearance of pores and excess oiliness for a refined texture. In its role as a skin conditioning agent, it supports the skin's barrier by enhancing softness, smoothness, and flexibility without greasiness. Typically found in serums, toners, and creams at low concentrations, it integrates into water-based formulas to deliver these effects during daily routines, contributing to an overall balanced and comfortable skin feel.
