It works really well ! I got the darkest color and did my eyebrows and lips - I left the stain on my eyebrows for like 30 mins and they were super dark, so I wiped it off with alcohol & did only the parts where hair was thinner (my eyebrows are already pretty dark) and slept through the night and put lotion on my face and still there. I haven’t washed my face yet but will see. My lips stained really good too, almost too good lol I slept with it and even tried to wipe it off twice and it barely budged lmao so 10/10 product!
