Review (4/5): Darker Eyebrows!
Definitely don't keep it on too long it will cause slight irritation but if you do it according to the instructions it's fine. I prefer using a mascara brush then the brush that it came with to apply. I wish the capsules were easy to open though. After attempting 2 capsules during different applications using so much energy to get these open i resulted in just using scissors to cut an end.
