What happens if one uses 70% Glycolic Peel on hands and legs?

Thanks for your query. Glycolic peels lighten the skin. It comes in various strengths. 70 % glycolic acid peel is a strong peel and should be used only by a dermatologist. There is a high chance that you might have burnt the skin. It is advisable to visit a dermatologist as soon as possible. Hope it helps.All The Best

even 70% glycolic acid is not a very deep peel and the results could not last for 6 months if any results at all.  Make sure you are using a cleansing bar and not a soap and apply Vaseline on moist skin after your shower
