I recently bought 30% glycolic acid peel, tried it yesterday on my face, it stung a little for a while, that's normal. But I thought I would see something happening on my face? Not that my acne and scars would be gone overnight, but I thought the skin would be peeling or something? I've tried many things on my face and If I don't see any results I always think it doesn't work 
so I'm just curious if that's right and if I should continue with that peel. Thank you 
Its a medium strong ratio the peel you used. If you are not sensitive it is not necessary to feel smth. I guess i mild redness. I am not sure about flakiness or other things. My skin is very tolerant and i never have the slightest irritation when i use smth. But i have seen improvement on red marks. You have to repeat it sometimes to notice if there is any difference. Dont forget your spf!
30% will make a difference, and weekly use will clear you up beautifully.
I have oily skin, and with 20% glycolic peels, I actually did not see peeling on my skin.
My skin did clear up, but I didn't see the "skin peels off" effect.
My skin is able to tolerate a lot, so maybe that is why. Maybe peeling is not necessary?
