I began using Tretinoin .025% cream approximately 10 weeks ago when it was prescribed to me by my dermatologist. So far, my skin is continuing to get worse, which is extremely frustrating. Should I continue the use of it? I've heard that by the end of the third month of using this product, results can be seen. I have maybe 50 closed comedones mainly on my forehead, but also on my cheeks and chin. Before starting Tretinoin, my skin only had 2-3 pimples at a time. Also, I began using Doxycyline Hyclate (200 mg a day) about two weeks ago, and I use Clindamycin Phosphate Lotion in the mornings. Nothing seems to be working. Thank you for your help!
