I’ve purchased the glycolic acid, lactic acid, salicylic acid and the 15%glycolic gel... all are amazing products. The salicylic acid is great for spots and large pores, the lactic acid is great for hydration my skin feels so smooth after using it and the glycolic is great for wrinkles and makes your skin brighter. The price for all products are really reasonable too Considering the quality plus they last a good few months too depending on how much you use them, I use at least one of them every other night so is value for money. Go ahead and try them you won’t regret it! I’d also recommend getting one of the chemical peel brushes too.
