WOW day 4 the spot on my upper cheek that frosted so badly just peeled right off after a shower. I was drying my face and it rolled off. Underneath clear, smooth, pink skin NO brown whatsoever just pink! I am totally absolutely elated! Can you tell? The other two spots my larger bad ones are still hanging on for now. But they will peel it is just a matter of time! YES I will be doing my entire face, neck etc later on this fall when the weather cools. IF please IF you do the 18% be sure to spot check yourself first no more than 2 layers!
