Review (5/5): Potent glycolic acid lotion
Hard, coarse skin is what I have, so I use this lotion to exfoliate my face 1-2 times a week. It's very effective & quick. I only need a tiny amount (pea-size) & it can sting fresh skin for a minute or two (it doesn't sting when my skin is coarse) & especially any current scratches or papercuts.
The bottle is large & lasts for years. Hard to find but well worth searching for & glad its available via Amazon.
