Auto-generated CPSR Part A draft with source citations
Function
Alpha-keto acid (MW 88 Da) used as a versatile medium-depth peel agent at 40–70% concentrations. Converts to lactic acid on skin contact, providing combined alpha-keto acid and AHA activity. Penetrates deeper than glycolic acid at equivalent concentrations due to both mechanisms. Has keratoplastic and keratoreconstructive properties. Requires careful neutralisation protocols due to volatile, pungent fumes during application.
Safety Rating
MODERATE
