acne
"Honestly I've used this and it's the 0.05% one I believe and I've been using it daily it's really cleared up my acne like a lot at first I had a big break out and then I used this and once I started it the first few weeks it got worse and until 2 months later of using this it's gotten so much better but the only thing is that my acne scars "post Hyperpigmentation" is taking for ever to go away.."
