Didn’t work for me and hurt my skin

I used this when I was a teen. My acne started when I was 11 and has stayed till recently, when I started on orratane. I used benzac together with Diane 35 and anti biotics when I was 13 and with out antibiotics again at 17! It didn’t work at all, and burnt my skin, I still have the marks from where it damaged my skin!
