That ish can get actual complicated, actual quick—particularly in relation to chemical exfoliants. Like, “alpha-hydroxy acid” (AHA) and “beta-hydroxy acid” (BHA) look fairly related, proper?

    What’s AHA?

    The abbreviation AHA stands for alpha-hydroxy acid, an acid primarily used as a chemical exfoliant or liquid exfoliant (versus a bodily exfoliant, like a gritty face scrub). The preferred AHAs are glycolic acid, lactic acid, mandelic acid, malic acid, and tartaric acid, and chances are high, you’ve got used them earlier than. But when not, this is how they work and who they’re greatest for:

    The pores and skin advantages of AHAs:

    AHAs are superficial exfoliants (that means they exfoliate the highest layer of the pores and skin) that assist deal with melasma, solar injury, pimples, and superficial wrinkles (by stimulating collagen manufacturing), says dermatologist Adarsh Vijay Mudgil, MD. AHAs aren’t solely good for fading hyperpigmentation—they’re additionally nice for exfoliating the pores and skin and stopping breakouts, in keeping with dermatologist Shereene Idriss, MD, since they dissolve the glue between useless pores and skin cells, serving to to stop clogged pores.

    The perfect pores and skin sort for AHAs:

    Along with their exfoliating properties, AHAs are identified for being considerably hydrating on the identical time—a plus for these with dry pores and skin. And should you’re coping with simply irritated pores and skin, lactic acid is thought for being an excellent AHA for delicate pores and skin (though it’s best to all the time spot-test new merchandise). As dermatologist Loretta Ciraldo, MD, beforehand advised Cosmo, these with tough pores and skin texture from very dry pores and skin may benefit from utilizing lactic acid (essentially the most hydrating exfoliator within the AHA household) to hydrate because it exfoliates. In case your pores and skin can tolerate one thing slightly stronger, attempt glycolic acid, which is likely one of the simplest AHAs.

    The place to use AHAs:

    In your face, in your again, in your butt—you’ll be able to even use AHAs in your ft in a foot masks. AHAs are tremendous versatile and are available tons of various codecs, like toners, peels, masks, or serums, however there is not any have to double up and use them in each single product (please do not). Discover a product sort that works for you (these with longer contact time normally work greatest, however they are often extra irritating), and stick to simply that one.

    The right way to use AHAs:

    Board-certified dermatologist Saya Obayan, MD, beforehand advised Cosmo that should you’re new to acids, one of the simplest ways to include them into your routine is to begin with a low share of glycolic acid (like 5%), and slowly work your method to 15 or 20%. When you’ve got delicate pores and skin, board-certified dermatologist Neal Schultz, MD, beforehand advised Cosmo that it’s best to begin out making use of a light exfoliant resembling lactic acid as soon as per week for a couple of weeks and steadily enhance to a few to 4 occasions per week. In the event you want one thing stronger at that time, swap to glycolic acid.


    What’s BHA?

    Now, let’s get into BHAs. This acronym stands for beta-hydroxy acids, and it is also a chemical exfoliant. Essentially the most notable BHA is salicylic acid, however willow bark extract is a well-liked light various. Though there is a slight overlap between the advantages of BHAs and AHAs, they have some key variations, so let’s get into it.

    The pores and skin advantages of BHAs:

    Likelihood is you’ve got used salicylic acid a time or two on a pimple. Why? It is one of the widespread elements for treating whiteheads, however it additionally works for inflammatory pimples as properly. “As a result of salicylic acid is an anti-inflammatory ingredient, it additionally decreases the redness and irritation that comes with pink, tender pimples,” board-certified dermatologist Rachel Nazarian, MD, beforehand advised Cosmo. “And because it breaks the bonds between the pores and skin cells, it additionally gently exfoliates your pores and skin to assist stop the formation of pimples.”

    The perfect pores and skin sort for BHAs:

    Because of their antibacterial properties and talent to penetrate deeply into the pores and skin, BHAs are ideally suited for treating oily, acne-prone pores and skin and enlarged pores, Dr. Mudgil explains. When you’ve got naturally dry pores and skin, rosacea, or eczema, use warning with salicylic acid and seek the advice of your dermatologist first.

    The place to use BHAs:

    As a tried-and-true pimples ingredient, sal acid is mostly present in spot remedies, physique washes, and cleansers for pimples. Though you would not need to go overboard on BHA (irritation? No, thanks), you’ll be able to apply salicylic acid in most locations, like in your chest and even in your scalp with shampoo you probably have dandruff or scalp pimples.

    The right way to use BHAs:

    For essentially the most half, OTC salicylic acid merchandise may have concentrations someplace between 0.5% and a pair of%, however JSYK, extra doesn’t all the time imply higher. Very similar to retinoids or AHAs, begin low and work your method as much as a stronger focus in case your pores and skin can deal with it with out irritation.


    Which is best, AHA or BHA?

    Reminder, this is not a contest. Simply discover what works for you and run with it. AHAs and BHAs are each unbelievable for pores and skin, however they won’t be wonderful for everybody (pls see the part above the place we go over the perfect pores and skin sorts for every acid). To sum it up, AHAs are higher for dry pores and skin and people trying to tackle pigmentation, whereas BHAs are higher for greasy pores and skin and pimples. And should you’re somebody who has considerations that fall on either side, you may need to think about using a product that accommodates each AHAs and BHAs. Whaaa?! You are able to do that?? Yup, you should utilize them each, however you need to watch out.

    Can you employ AHA and BHA collectively?

    “For folk which have acne-prone pores and skin or enlarged pores and sun-damage or pigmentation points, a mix product is an efficient possibility,” Dr. Mudgil says. “The mixture might be extra irritating, although, so it is vital to be conscious of the results on one’s pores and skin.” Attempt just one chemical exfoliant at a time—at the very least at first—and see what your pores and skin can deal with. In the event you appear to tolerate exfoliants fairly properly, use a product that accommodates each AHAs and BHAs as an alternative of attempting to mix them by yourself.

    The ultimate phrase on AHA vs BHA

    Neither ingredient is best than the opposite per se, however one may be higher for you. As Dr. Mudgil explains, in case your points are sunspots and nice strains, you actually solely want an AHA-containing product. If you do not have solar injury however do have enlarged pores or acne-prone pores and skin, you seemingly solely want a BHA-containing product. When you’ve got solar injury and acne-prone pores and skin or enlarged pores, a mix AHA/BHA product could be essentially the most complete resolution. And keep in mind, once we’re speaking about exfoliating, particularly should you’re simply beginning out or attempting new merchandise, much less is greatest.
