How to relieve redness due to exposure after using tretinoin cream?
Patient: To treat my acne, late last year I applied Tretinoin cream to my face. Soon after applying the cream I went outside and exposed my face to the sunlight with no protection. Its October 2012 now and my face is very red/sensitive/irritated. Could you guide me in the right direction to possibly fix this problem? Thank you. Doctor: Hello,  This is seven years later. The problem isn't relevant anymore. Well, it is a sensitizer to sun so, you'll want to avoid using it and having sun exposure at the same time.  Hope I have answered your query. Let me know if I can assist you further.  Take care  Regards, Dr Matt Wachsman, Addiction Medicine Specialist
