Mandelic Acid

Mandelic Acid is an alpha hydroxy acid (AHA) derived from bitter almonds, featuring a larger molecular structure than glycolic acid due to its aromatic benzene ring. This larger molecular size results in slower, gentler penetration into skin, making it particularly suitable for sensitive skin types and darker skin tones where post-inflammatory hyperpigmentation is a concern. Formulators favor mandelic acid for its dual exfoliating and antibacterial properties, as it's lipophilic enough to penetrate pores effectively while providing keratolytic action with minimal irritation compared to other AHAs.
