Did I just ruin my Vbeam Session? And is it safe to go for another session in a week?

3 weeks ago I had my first session of vbeam. There were no complications. I get the occasional pimple so was prescribed 1% clindamycin to put on affected areas. I have been using it for a couple of days and now my face is patchy, bright red, dryish, hot, stings when I use skincare products which are otherwise gentle and have broken out all over my face! I'm really worried that I've reversed the effects of the vbeam. Also, my next session is in aweek, can skin in this condition undergo treatment?
