Science & Benefits
A dicarboxylic acid that acts as a multi-functional logic hero. It is a selective antimicrobial (targeting C. acnes), a tyrosinase inhibitor (fading post-acne marks), and a keratolytic. Unlike BHA/AHA, it is highly tolerated by sensitive skin. It is the logical choice for treating both active inflammatory acne and the lingering redness (PIE) that follows.
