What the gurus are saying

This 4% isn't for active breakouts (the 2% is), but it's well-formulated with soothing ingredients like oat and green tea. If you have active hyperpigmentation or dark marks, skip it. Your barrier needs to stay calm to fade marks, and irritation will set you back. Those who've used the 2% for six months without irritation and plateaued on texture might try it at 2-3 times weekly, watching for dark marks or sensitivity.

"But for melanin rich skin, the risk benefit calculation is different than it is for someone else. Do not touch the 4% if your main concern is active breakouts or acne, the 2% was specifically formulated for that and the 4% wasn't. [...] If you currently have active hyperpigmentation or dark marks, please do not jump to a higher acid concentration, you need your barrier stable and calm to fade existing marks, irritation will set you back, not move you forward."

"I've repurchased this several times. I typically use it just on my nose or wherever you get clogged pores or large pores. It's fragrance-free, alcohol-free, and contains 4% salicylic acid, which actually [...] penetrates into the pores whereas other exfoliating ingredients sometimes just penetrate to the surface level. Salicylic acid penetrates a little bit deeper, which makes it one of those great ones for clogged pores or acne."

"I've repurchased this one over the years multiple times, maybe a dozen or more. And now that I've run out of it I'll probably pick it up again. Sometimes this one with that extra 2% of BHA really does the trick, and I like it for that."

"The pH of this one is definitely higher, looks like it's probably about a four. That's probably going to be okay. At least for me, I found it effective but not much higher than that."

"It's got the 4% salicylic acid and it also contains oat and green tea, both great for soothing. A little bit of it goes a long way. A bottle like this you use it two or three times a week and it'll last you about three months or so. It's got a nice light texture. It's been around for a long time, and if there's any brand that is more respected for their exfoliants, Paula's Choice has to be number one. When you think of exfoliants, I think of their 2% BHA toner which is a cult classic."

"I ran out of the Paula's Choice 4% BHA and I didn't really like the texture, and I don't get pimples that often."

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.
