Nay or Yay?
4 April 2026
Nay
It's different from a leave-on product like say The Ordinary's glycolic toner, that's different. You don't want to put that on and then follow up with your retinoid. You're going to run into trouble.

Yay
I like this glycolic acid because at least one it explicitly states just how much glycolic acid you actually get in this toner. Sometimes AHA serums don't tell you how much AHA you have in the toner. With this one it's just clear, they make it clear that it's 7%. [...] I use this two to three times a week on my face.

Why we only pair takes from the same month

A formula gets reworked, a price moves, and a product people loved in one year is not the product they are handed in the next. Two takes far apart in time can look like a disagreement when they are really a description of a product that changed. So a face-off only pairs experts whose videos went up within a month of each other, and neither take here is sponsored.
