I have used this mask for about three weeks and I have noticed that compare to the Cosrx salicylic acid cleanser this one gives me more of a deep cleanse and goes through my pores and cleanse them better. I first used it with the sparkling powder one as included with the set and it gives me a great feeling of "pooping"  like candy on my face. At first I thought it was gritty and little bot like sand but when I mixed it with water and the foaming cleanser it became a more of a thick grayish foam and started to make the popping sound. When I put it on my face I left it on for 1 minute just as I do with the Cosrx one. Compare to the Cosrx one (which only brought my gunk to the surface) it washed away my gunk on nose with just water. Although I have not noticed any reduction in my scars it does leave my skin brighten, pore-less, and clean.
