I started using Retin-A 15 weeks ago and by the third week I started to break out again and I thought it was the purge but now I'm on the 15th week and still have been breaking out. I have Hyperpigmentation scars that are so bad and have only gotten worse. I get more breakouts and I Everwood. And it's just bad in general. I wish I never would've started it in the first place. Can I stop using it?
