What is Succinic Acid?

Succinic acid is a simple four-carbon dicarboxylic acid naturally produced in the body during cellular metabolism and obtainable from plant fermentation or amber. In cosmetic formulations, it acts mainly as an antimicrobial agent targeting skin bacteria, a pH adjuster to optimize product stability and compatibility with skin, and a buffering component to resist pH shifts. It provides mild exfoliation by promoting cell turnover and aids in odor masking for better sensory qualities. Commonly featured in cleansers, toners, serums, and acne-focused products, it helps maintain formulation integrity while contributing to a refreshed skin feel. Its water-soluble nature ensures even distribution in water-based products, enhancing overall efficacy without compromising gentleness.
