I've had comedonal skin since I was 13. I tried Salicylic acid and even The Regimen, but neither the BHA nor the benzoyl peroxide could clear my skin. I received tretinoin .05% on July 8, 2014 and have been using it ever since. Today is the 31st, so I have been using it for 23 days. It's bringing the contents of my blocked pores to the surface, but it'll take a few more months to see results. I'm pretty hopeful! Here's the condition of my skin today.
