I have been using this pad for 1 month, and about 2-3 times a week. I notice it was a huuuuuge difference "before and after" using this pad after 1 month usage. Until last month my skin was so dull, rough, so many papulles, blackheads, whiteheads. And now it is so healty, bouncy, no more blackheads and whiteheads. My face is also smoother and brighter than before. All my skin problems are solved!!!! Absolutely recommended!!!
