How can I replace Retin A (tretinoin) in my skincare routine while still fighting acne/maintaining skin quality? 3 yrs use, my skin is just too reactive. Thanks!!

Several options. Acne is a serious, chronic disease that is a grave social and professional liability. Managing it is not pleasant, but you need to do this until it remits on its own. I'm sorry. Try replacing your retinoic acid with benzoyl peroxide; if you cannot tolerate this either, or if it does not keep you clear, you will need prescription-strength medication from your physician. Hang in there and best wishs.
