Hi, I had a sudden acne outbreak and it has persisted for about a month plus. I went to see a dermatologist and was prescribed a one month course of oral antibiotics (doxycycline), Clindamycin phosphate 1% gel and Differin. I went to read up online on these products and understand that they might cause purging, especially Differin. Some people also complained of excessive redness/burn marks etc after using Differin. It puts me off and I dare not try it now. Is it true that Differin is that strong? Is it worth going through the purging stage?
