I used it for a while when I was about 17-18 and had the same results as many. My face was nasty for the first 2 weeks. SUPER dry & very red & patchy. Then, it magically cleared up for about a month, then I started breaking out worse than before I started using Proactive with no changes to my skin care regime. Same thing with my sister who was about 13 when she used it.
The doctor then put me on BCP, but they didn't work for me. They did work for my sister, though
You could try putting her on BCP...just a thought.
Tanning's really the only thing that helped with my skin.
I'm older now & I don't get big zits anymore, but I'm full of blackheads. Still haven't found anything for that...
