I'm just starting to incorporate Retin-A (tretinoin version) into my skincare routine. I normally use Tarte Maracuja Oil at night as my mositurizer. After I was my face, can I still apply the oil, wait about 15-20 mins and then apply the trentinoin? I want to make sure the oil is OK to use with the trentinoin and if should apply it before or after the trentinoin.
