Hi everyone, I have been struggling with perioral dermatitis for about 3 months now. it is flaky and dry around my mouth with small bumps and redness. It got a lot worse so I went to the derm and she prescribed doxycline and an antibiotic cream.it has seemed to go down a little but is still present and flares up badly sometimes. I don't want to be on this drug forever. I am using Osmia organics to cleanse. Does anyone know if sweating or heat can make it worse? I love hot yoga but I think it makes it flare up. Also does anyone know if it is caused by hormonal birth control? I have been on it for about a year and read that this could be the cause. Any advice would be greatly appreciated thank you!!!
