Pre-soaked cotton pads filled with AHA, BHA and LHA. It has one side embossed and one side smooth so you can choose to wipe-off or leave on. Same like the toner, it also contains 10000ppm tea tree extract, that aims to calm the skin after the exfoliation. There is not much essence in the tub but the moisture the cotton pad holds is also ver sufficient to use as a 10 mins quick mask for instant cooling and calming benefits. It is very mild and I usually use 2-3 times per week. Very gentle on my dry sensitive skin too! It somehow helps to control my sebum production
