Winter is coming and my skin is changing,entirely. Three weeks ago I was told my skin was the best looking ever, now its mottled. 2 days ago I started mixing my Tretinoin(retinal A) half and half with my Dove sensitive skin facial lotion fragrance free dye free. Does this seem like a good idea or would I be better mixing it with EVOO or some other natural oil? Even my hair is looking dry. Is it age or what. Can it be the Trentinoin, that's what I thought.
