What the gurus are saying

This 12% multi-acid blend delivers visibly smoother skin and diminished blackheads by morning, but it's strong enough that those already using potent retinoids need to space it out. The formula combines glycolic, lactic, gluconolactone (a gentler PHA exfoliant), and salicylic acid for effective pore refinement and hyperpigmentation reduction.

"It's the PSA Skin GOALS, this one's 46 bucks so it's about half the price. [...] I really really enjoy this brand, they're the cousin brand to Allies of Skin, the more affordable lineup. This one's got a 12% blend in here with glycolic acid, gluconolactone, lactic acid, and salicylic acid. Gluconolactone is more of a PHA exfoliant which makes it even more gentle. [...] So this one's really nice, it's got all of it going on, proper pH, serum-like texture, very lovely product."

Exfoliate Your Way to Younger Skin 💪🙌 Top Exfoliating Products to Induce Collagen Production

"This one's got a serum lotion texture to it as well. I'm very close to being done with this bottle. [...] No fragrance, none of that. PSA Skin was started by the Allies of Skin and then they sold it to another company. So [...] the brand's still pretty much the same as far as I understand."

"This is the PSA serum with exfoliating acids. It's a great product, very strong, and I have to use it only occasionally because I already have a lot of strong exfoliants in my routine. I just didn't gauge properly how long it would realistically take me to finish something this strong."

I Can't Finish These...My Mistakes & Product FAILS

Hyperpigmentation: What Worked/Didn't Work for ME!

"The product I have right now instead is the PSA Goals serum. I very much believe in this category of high strength glycolic acid products, I think it's one of the best options for hyperpigmentation and it comes at a wide range of price points. That said, I have to space it out because I also use a strong retinoid, adapalene, and combining the two would not go well, so I don't use it as much as I used to."

What the evidence says.

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

Niacinamide

Niacinamide has evidence behind it for redness, uneven tone and supporting the skin barrier, and it is usually well tolerated even by skin that reacts to most things.

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.
