Early verdict · Few reviews so far

What the gurus are saying

This gentle exfoliant delivers visible results in glow and even tone without irritation, even for rosacea-prone skin. It combines AHAs (mandelic and lactic acid) and the PHA gluconolactone with hydrating panthenol and glycerin. That means even those who normally react to exfoliants find they can use this twice weekly without irritation.

"My favorite exfoliant of the year has to be the Skin Rocks Gentle Acid. [...] This is an exfoliating toner formulated to deliver all the benefits of exfoliation without the irritation, containing AHAs and PHAs and skin conditioning ingredients. I have struggled with exfoliating toners this year, [...] but this exfoliant has just been so nice to use, non-irritating whatsoever. I can happily use this twice a week, which just shows to me how gentle this really is."

"I think this one, the Krave Beauty one, and there's one more that I can use without any problem. [...] My skin doesn't even know this is being used. [...] Other than looking more hydrated, more even, a lot brighter. It's like I'm just spreading water on my face. My rosacea does not care. In here, we have Mandelic Acid, which helps kind of stop that hyperpigmentation. With Lactic Acid and Gluconolactone [...] to help actually physically exfoliate the skin."

"I would sometimes do Gentle Acid in my routine. I don't have empties of it because I haven't worked my way through a big fat bottle yet."

What the evidence says.

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

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.
