I have no idea. I started using clindamycin and differin 4 weeks ago and I cannot believe how bad it's made my skin. I'll wait it out for the full 8- 12 weeks to see improvement, but I'm scared . My skin's scarring really badly. Gaaah.

make sure you are using a good moisturizer. Some times it gets worse before it gets better, but if it doesn't show signs of improvement or it is more like a rash, i would call the doctor. You could be having an allergic reaction the clindamycin
