"This is a great gentle exfoliant that helps to refine skin texture and promote smoother and clearer skin. The combination of AHA and BHA is really ideal for those who are seeking exfoliation and who have a little bit more acne or clogged pores at the same time want to brighten their complexion or improve post acne marks. I would say this is pretty gentle. So for someone who is acne prone and wanting to use something that can help with their texture and tone, I think this is definitely something that you can use a little bit more regularly depending on your skin type. It's kind of like a mist that combines mild concentrations of AHA and BHA. Glycolic acid is one of the active ingredients along with betaine salicylate, which is basically a derivative of salicylic acid, along with apple fruit water and willow bark water. Willow bark is a natural derivative of BHA."

"The AHA BHA Clarifying Treatment by COSRX is a product that I think was launched somewhere in 2022 or maybe before. It's a really really good product, it is supremely supremely gentle and it gives you the AHA BHA benefit. These options have AHA BHA both of them so you can really get the benefit of both the ingredients in one product without really going ahead and thinking they are gentle enough for daily use. By daily I mean a couple of times a week and you will see maximum benefits from it."

"This is more of an active, but it's an active I think most people will be able to benefit from. It's the COSRX AHA/BHA Clarifying Treatment Toner, which is 19 bucks. In here we've obviously got salicylic acid, which is great for so many things. [...] It's one of the few ingredients I added into my routine where I knew a difference, I could tell a noticeable difference in my skin very quickly. It's great for redness, it's great for acne, it's great for hyperpigmentation, it's great for hydration, it's just a wonderful ingredient all around, and it's really great if you have suffered from blemishes, dark spots. My acne got a lot better when I started using this. I highly recommend everyone try salicylic acid at least once, and this one also has some nice ingredients too, snail mucin, centella, niacinamide. Wonderful product, and pretty affordable as well."

"I've decided to just stick with this AHA acid toner. This tends to cost less, about half what the pricier one costs. I actually prefer the other one's texture, but in terms of results I feel they compare, so I'm willing to save a little more money and go with the product where the texture is not a favorite, but I like the results."

"This is the AHA BHA clarifying treatment toner, and honestly it isn't a bad product, but I have some bones to pick with it. It has glycolic acid at 0.1 percent and betaine salicylate at 0.1 percent, so calling it the AHA BHA clarifying treatment toner sounds like it's going to do so much more for your skin than I've found it to do. I also don't like that it's in a spray bottle, because in spite of being a spray toner you're not supposed to spray it all over your face, you're supposed to spray it onto a cotton pad. What it's really for is prepping your skin after a more alkaline cleanser with its low pH, which is kind of dated since most people aren't doing that anymore, but if you are, this could be a good addition to your routine."

"I use low percentages more often with great results, and this is a very low percentage double chemical exfoliant that's really gentle and can be used as a daily exfoliant. It has betaine salicylate, which is a moisturizing version of BHA, and glycolic acid as well. It's very gentle and works on texture and tone without over-exfoliating."

What the evidence says.

Independent of what the gurus think, this is what the published research supports about the main active ingredients here.

Salicylic acid

Salicylic acid dissolves in oil, so it can get into a pore rather than just working on the surface. That is why it has long-standing evidence for blackheads and milder acne.

Alpha hydroxy acids

Alpha hydroxy acids loosen the bonds holding dead cells at the surface. The evidence supports smoother texture and more even tone over time, and they can leave skin more sensitive to sun.

Humectants and emollients

Ingredients like these draw water into the surface layers and slow how fast it leaves. The evidence is for comfort, softness and hydration rather than for changing the structure of the skin.
