Is Tretinoin Causing My Red Face ?

I am taking Tretinoin Gel 0.025% along with Minocycline 100mg for acne , however I noticed my face has become rather dark and red compared to the rest of my skin . I am using a moisturizer as well and my skin isn t burning or scaly, just red and a bit warm. It isn t bright red, but not my normal very pale color. I stopped using it for a day to see if it was irritating my skin, but the redness persisted. I am questioning whether I continue usage because I know Tretinoin gets rid of red skin or if I should stop to see it is goes, if so for how long, and then see a doctor to try something else?
