What the gurus are saying

This toner earns devoted loyalty from those who make it a staple of their routine, with one expert calling it her go-to control product she never runs out of. The key thing to know is that pH matters here, if the bottle's pH has drifted, you won't get the results you paid for, so it's worth checking before use.

"Lotion P50 is like... when it comes to skincare it is my p50. I'm not super loyal to much more than a handful of products, and this is one of them. I can make anything work, but this is something I always have stock of, I'm never going to be without it."

"If you're buying the uh oh what's that brand biology garge they're a really expensive p50 uh lotion uh and you're spending 100 bucks on it you want to make sure the pH is proper that you're going to get the expected results otherwise if the pH is way a skew you're not going to get what you paid for"

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.
