I love chemical peels and they have been part of my routine for a long time. I always use them twice a week, in the evening, followed by a mask. I don’t have sensitive skin, I am 36 (wrinkles) and I think I already have sort of a build up tolerance for chemical peels. That being said, these were very weak. They do say these are low irritating which is definitely true and are perfect for young or sensitive skin. Or for someone who like to use them daily. If you are used to brands like Dr. Dennis Gross (fantastic pads) these won’t do. If you are new to chemical exfoliation go for it and after finishing the packaging try to upgrade to something stronger for more visible results.
