Purpose
Function
Smallest AHA (MW 76 Da) enabling the deepest epidermal penetration of the AHA class. At <25% produces superficial exfoliation; 25–50% causes keratinocyte discontinuity; 50–75% causes epidermolysis. Disrupts desmosomal cohesion via calcium ion chelation, thinning the stratum corneum and promoting cell turnover. Efficacy governed by free (undissociated) acid concentration per Henderson-Hasselbalch: at pH 3.5 (~68% free acid) vs pH 4.5 (~18% free acid). Also used as pH adjuster.
