Week 1 has come to an end. I experienced peeling and burning . my chin and nose is where I experienced the most peeling and burning. Even putting on lotion or using cetaphil burned. I only put a pea size on my face but I guess since the strength is .1% it's strong. My face is basically the same I haven't seen a diffrence the only thing is that my chin looks clearer than before. I haven't got any pimples so that's good. I still got months to go so this is just the beginning.if you have any questions or comments please don't be shy to ask.
