Hello. I have been using tretinoin for my acne since a month and I did not get any irritation or purging. My acne is healing to some extent and I have normal to combination skin type and I use the Minimalist vitamin b5 moisturiser but I feel like this moisturiser makes my skin oily and red . I don't know which moisturiser would be good Please suggest any good moisturiser that I can use along with tretinoin. Thank you. Hoping to hear some suggestions.
