It is a strong chemical peel for sure. I couldn’t see the exact percentages of the ingredients listed but Glycolic acid is the second ingredient after water so i assume it is in high percentage. I can also tell that by the tingling it causes when i use it. It smells chemically too. All these are things that make it a great chemical peel. I use it for 10 mins and then wash it off. The before after photos are of my first time using it and i feel i can see the difference in just 1 use. Totally recommend it but be careful, patch test and don’t keep it on for more than the recommended time.
