Mandelic acid is a gentle yet effective alpha hydroxy acid (AHA) prized for delivering visible results without the intensity often associated with chemical exfoliation. Like other AHAs, it works by loosening the bonds between dead skin cells, helping reveal smoother, more luminous skin beneath. What sets mandelic acid apart is its larger molecular size. This means it penetrates the skin more slowly and stays closer to the surface, offering thorough exfoliation with a significantly reduced risk of irritation.

This gentle resurfacing helps improve skin texture, refine the look of pores, and visibly soften hyperpigmentation over time. Mandelic acid is also considered non-melanotoxic, making it especially well-suited for medium to deep skin tones, as it’s less likely to exacerbate discoloration or trigger post-inflammatory hyperpigmentation.

Beyond exfoliation, mandelic acid supports pro-aging skin goals by encouraging healthy cell turnover—something that naturally slows as we age—and has been shown to help stimulate collagen production. Its antibacterial and anti-inflammatory properties also make it a smart choice for acne-prone skin, helping to unclog pores, regulate excess oil, and calm redness.
