Now have used twice the mask. I have very sensitive skin and often inclined to rash in products. I had no redness or rash. Through the mask grease my skin a lot less. Blackheads are removed, except for the really deep-seated and sealed. But you're gonna get away with not stripes. The pull hurts, because the mask firmly attaches itself properly. But is bearable. It takes about 20 minutes until it is dry, and apply for the I use a brush. I find the product top, especially for the price! I'll continue to use it.
