Malic Acid

What is it?

A fruit-derived alpha hydroxy acid (AHA), often used alongside other AHAs like glycolic and lactic acid.

What does it do?

Alpha hydroxy acid explored primarily as a permeation enhancer and peptide-delivery vehicle component in recent transdermal-delivery research, and identified as a bioactive AHA extractable from plant sources. Direct clinical efficacy data on malic acid as a standalone exfoliant is limited compared with glycolic/lactic acid.
