acne
"After living on doxcycline for 2 years,finally found winning combo for MY perimenopausal hormone/stress induced SEVERE CYSTIC acne! Everytime I got off doxycycline, face worsened within 2 months (scarred and inflammed) than when I started. Would take 3 months of being back on the antibiotic, along with the retin A/hyperpigmentation combo cream that my derm helped develop before scarring became less noticeable. Doxycycline worked well (compared to clindamycin/minocycline/ OTC/proactive system and all salicylic acid, etc.); but, didn't want to live on antibiotics. 3 months changed to Bactrim & Aczone.  Within 2 months, as if I never had acne at all.  No scars. Aczone & MD's cream only for last month. No CYSTS or pimples. CLEAR SKIN!!"
