The masque was awesome in smaller doses (in my case, once a week as opposed to the recommended "Every 2-3 days").
It was very uncomfortable at first, and slightly burnt my skin. But afterward, it was smooth sailing. It's helped with existing breakouts, and helped prevent future breakouts quite well.
The brush that I received with the masque was not scratchy on my skin with application at all. The packaging and pumping feature made it very easy to use without exposing it to outside bacteria and gremlins.
This masque worked really well, I used it every 2nd evening and it really helped to target blemishes and leave my skin feeling smoother & healthier. It does tingle slightly, however not too much, not anything overpowering and I didn't leave it on for longer than 10 minutes. The packaging and the brush it comes with is very nice. Loved the ingredients (Lactic Acid, Salicylic Acid) and it is effective!
