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!
