Meet Mandelic Acid: The Nonirritating AHA That Resurfaces Your Skin

Audrey Noble

Whenever our skin is feeling dull and congested and is in serious need of overall rejuvenation, we turn to peels. They remove the top layer of damaged skin to promote the growth of newer, healthy skin and address skin problems like acne and hyperpigmentation. While it seems like we've covered everything that you need to know about peels, there is one in particular that has been flying under the radar. Say hello to mandelic acid.

To get a better understanding of what a mandelic acid is, we asked dermatologist Eva Simmons-O'Brien, MD, and Angela Caglia, celebrity facialist and founder of skincare brand Angela Caglia, to give us the breakdown of why we should seriously consider incorporating it into our skincare routine. Scroll down to see what they had to say.

What is a Mandelic Acid?

It's not some new, top-secret ingredient we've never heard before—it is another form of an ingredient we've come to know and love for our skin. "Mandelic acid is an alpha hydroxy acid (AHA)," says Simmons-O'Brien. "AHAs are good for the skin, as they work to loosen connections between impacted surface skin cells (called desmosomes) to allow the cells to shed naturally leading to a fresher, brighter complexion."

What are the benefits?

According to Simmons-O'Brien, you can expect the same skin benefits from a mandelic acid peel that you would expect from a normal one, such as cell turnover to firm up the skin. This one in particular is great for clearing pores and brightening the skin. "Acneic skin can get impacted and clogged, making this a good choice for clearing skin debris and smoothing the complexion," she says. "Mandelic acid has shown some benefits for brightening the skin as well, so it can help support a regimen to clear photodamage."

If you have super-sensitive skin, this might be the better peel for you. "It has a larger molecular structure than other acids, such as glycolic and salicylic, so it does not penetrate as deeply," says Caglia.

What to do Pre- and Post-Peel 

Just like any regular peel, avoid retinol use for at least three to five days before. "You should definitely stop using Retin-A and avoid contact with any acid treatment at least two weeks in advance," says Caglia. "Also this peel shouldn't be applied to tanned or sunburnt skin."

For post-peel activities, Caglia says to avoid any activity that will make you sweat. Simmons-O'Brien says to avoid the sun, as your skin will be more sensitive to burning under the sun's UV rays.
