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

Frequently Asked Questions

Is mandelic acid more gentle than glycolic acid or lactic acid?

Yes, mandelic acid is generally considered gentler than glycolic and even lactic acid. “It can be helpful for sensitive skin since it is less irritating than other AHAs,” says Dr. Moy. Its larger molecular size means it penetrates the skin more slowly, minimizing any sting and the likelihood of irritation. You’re still getting the smoothing, brightening benefits of an AHA—just without the intensity that can come with its faster-acting counterparts.

How often should you use mandelic acid serum?

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

Can mandelic acid be used with retinol or vitamin C?

Yes, mandelic acid can be used alongside retinol or vitamin C—but this is where pacing matters. As Dr. Moy puts it, “mandelic acid can be used with retinol and vitamin C, but it’s best to start with lower concentrations and monitor your skin’s tolerance.” This simply means don’t pile them all on at once. Ease in, see how your skin behaves, and adjust as you go.

Is mandelic acid safe for deeper skin tones?

“Mandelic acid products are safe for deeper skin tones because of their lower risk of causing post-inflammatory hyperpigmentation,” says Dr. Moy. Since it works more gradually than stronger exfoliants, it’s less likely to trigger the kind of irritation that can lead to discoloration, so you get the benefits without setting off a whole other issue.

How we test and review products

When Allure tests a product, our editors look at it from every angle in an effort to best serve you. We review ingredients, scrutinize brand claims, and, when necessary, examine peer-reviewed scientific and medical studies. In addition to testing each and every product that’s included in each and every review, we rely on experts who shape their fields, including dermatology, cosmetic chemistry, and medicine, to help us vet the ingredients and formulas.

For our list of the best mandelic acid serums, we considered each product’s performance across five primary categories: product ingredients and efficacy, packaging, fragrance, texture, and product wear. Every product was determined to have excelled in each category by our editorial team, which is composed of in-house writers and editors as well as contributors—along with special consideration from board-certified dermatologists.

Our staff and testers

A beauty product is a personal purchase. You might be searching for a face cream to address persistent dryness or a new nail product to add to your Sunday self-care routine; you may simply be browsing around for the latest launches to hit the hair market. No matter what you seek or your individual needs and concerns, Allure wants to ensure that you love anything we recommend in our stories. We believe that having a diverse team of writers and editors—in addition to the wide range of outside testers and industry experts we regularly call upon—is essential to reaching that goal.

After all, can we really say a skin-care product is the “best” for people over 50 if the only testers we’ve solicited opinions from folks who have yet to hit 30? Can we honestly deem a high-end diffuser worthy of your hard-earned cash if it’s never been tested on curls? We’re proud that our staff spans a wide range of ages, skin tones, hair textures, genders, and backgrounds, which means that we are able to fairly assess any beauty product that comes into the beauty closet.
