Good but not the best
It’s a good ampoule. Didn’t break me out (I have sensitive and very acne prone skin) but didn’t give me results yet. I’ve been using it for a month or so now but I didn’t see any visible difference in my acne marks. I will continue to use it and hope for the best!
You do get a generous amount tho! I’ve been using it for a while now and I still have more than half the bottle left.
