7 Best Mandelic Acid Serums for Acne, Dark Spots, and Sensitive Skin

FAQ

Is mandelic acid gentler than glycolic acid or lactic acid?

Yes, mandelic acid is generally considered gentler than glycolic and lactic acids. “It’s less irritating than other AHAs, so it’s helpful for sensitive skin,” says Dr. Moy. The larger molecule size allows for slower penetration into the skin, minimizing the potential for stinging and irritation. It provides the skin-smoothing and brightening effects of AHAs, but doesn’t have the intensity of faster-acting AHAs.

How often should I use Mandelic Acid Serum?

There’s no need to rush. “It is generally recommended to start using mandelic acid serum two to three times a week and increase the frequency depending on your skin’s tolerance,” says Dr. Moy. In practice, that means incorporating it into your routine, seeing how your skin reacts, and only dialing it up when things are calm.

Can mandelic acid be used with retinol and vitamin C?

Yes, mandelic acid can be used in conjunction with retinol and vitamin C, but pacing is key here. As Dr. Moy says, “Mandelic acid can be used in conjunction with retinol and vitamin C, but it’s best to start with low concentrations and monitor your skin’s tolerance.” This simply means don’t pile it all on at once. Relax, notice how your skin moves, and adjust gradually.

Is mandelic acid safe for darker skin tones?

“Mandelic acid products are safe for darker skin as they have a lower risk of causing post-inflammatory hyperpigmentation,” says Dr. Moy. Because it works more slowly than harsh exfoliants, it’s less likely to cause irritation that can lead to discoloration, and it works without causing additional problems.

How to test and review products

when allure Once we test a product, our editors look at it from all angles to ensure we can best serve you. We check ingredients, scrutinize brand claims and, when appropriate, research peer-reviewed scientific and medical studies. In addition to testing every product included in each review, we rely on experts in fields such as dermatology, cosmetic chemistry, and medicine to help vet ingredients and formulations.

For our list of the best mandelic acid serums, we considered each product’s performance across five main categories: product ingredients and effectiveness, packaging, fragrance, texture, and product experience. All products have been determined to be outstanding in each category by our editorial team of in-house writers, editors, and contributors, with special consideration by board-certified dermatologists.
