"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'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 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.
