"This one's a really nice option. It's 3.38 ounces and it's $10.50, so this one will save you about $25ish dollars. It's got 2% salicylic acid. It's got licorice root and [allantoin] for soothing. Yeah, so it's a very nice alternative in my opinion to the [Paula's Choice], which is getting kind of pricey."

"I think Isntree is a little bit of a nicer experience, a little bit more hydration, a little bit more plumping, a little bit softer, a little bit gentler on the [...] skin. I really do appreciate the way that this delivers into the skin with a kiss of hydration. [...] I am happy with it not just as a cheap dupe, but I think as in some circles a superior product."

"I really like that there's some extra humectant ingredients in here. This almost feels more like an exfoliating toner than an exfoliating liquid, [...] where it [...] has a slightly more hydrating kind of feel that is just a little bit more pleasant, especially if you're into texture or if you just need every ounce of hydration you can get. I also like that they've included willow bark extract along with the chestnut extract. These are two what I call clarifying ingredients."

"Isntree Chestnut BHA 2% Liquid is also a goodie. It's [...] one of my favorite ingredients that checks all of these boxes for controlling inflammation and exfoliating the skin. [...] I like it because it's not just [...] anti-inflammatory and exfoliating, great for controlling acne, but it also has an additional benefit for helping to control redness."

"I've actually refilled it with the Isntree Chestnut BHA 2% Clear Liquid. I like this bottle because it actually sprays upside down and I love the BHA exfoliation for my back which can be prone to breakouts."

"This one is great because number one it does contain B so even though BHA we think of it more for like pore congestion acne oiliness it does also offer some chemical exfoliating benefits"

"Isntree Chestnut BHA 2% Clear Liquid, I really like it. It's really helping to smooth the skin surface and it's not irritating, although I did find that I've been putting it on my neck and I did find that I got a little bit of dryness back here."

"My favorite BHA toner is the Chestnut BHA 2% Clear Liquid. [...] It does contain 2% salicylic acid, [...] but what's different is that it's using a bit of a higher pH, around 3.5 to 4 last time I tested it, and newer research suggests salicylic acid [...] is not pH dependent the way AHAs are."

"This is an easier salicylic acid product for me to use, and because I have sensitive skin that's tough to disrupt my barrier so much, this is a great fit for me. As for texture, this one is very watery, so I prefer to apply it with a cotton round. I don't smell anything in this product. I do think it's interesting that they included chestnut, but I feel the real hero ingredient here is of course the salicylic acid."

"They have a BHA Chestnut exfoliating liquid that's like a K-beauty version of the Paula's Choice toner, amazing if you have blackheads."

K Beauty That Actually Delivers

"And if you've ever used a BHA before, you know that salicylic acid has a tendency to almost like irritate the skin or it can dry it out because it's oil soluble. This is so nice. The chestnut is so soothing. This is like the K beauty version of Paula's Choice BHA exfoliant. It's like the more gentle K beauty version. I love this. It is soothing to the skin. It is wonderful, but it actually does the job. It just does it at a more gentle rate."

"This is one of their new products and it is the most gentle BHA toner that I think I've ever used. If you have acne, this is phenomenal. It's for normal to dry skin, but I think oily skin can use it too. [...] I absolutely freaking love it and I love to apply this at night."

"They help with acne-prone skin, but for a lot of people they can be trying and harsh. This one, this has blown my mind. This toner is like the gentle alternative to the Paula's Choice BHA toner. I have fallen in love with this. And for winter, there are other ingredients in here that act as antioxidants. Why didn't this exist earlier?"

"I have to say this is probably the most gentle BHA that I've ever used. I feel like I can use this before I go out during the day. It is a really light liquid and it just soaks into skin so well, and it doesn't irritate [...] the skin the way that a lot of other BHA products do. This one does have that salicylic acid, but it also has chestnut extract which is wonderful, as well as sodium hyaluronate which is [...] the salt form of hyaluronic acid and it's really nice and hydrating to skin."

"This is a salicylic acid exfoliating product, and it's really really nice. It's again non-intrusive on the skin, it feels like a lightweight toner with no redness, no irritation, no stinging. They use upcycled chestnut shell, so this is the waste from the chestnut industry that they take and extract for this product. Salicylic acid removes dead skin cells, unclogs pores, helps with clogged pores and blackheads, smoothing out skin texture."

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.

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.
