I use Tretinoin gel 0.5 percent three nights a week. I use Timeless Vitamin C Serum every morning, and on the nights I don't use the Tretinoin. I also use sunscreen everyday. I've been doing this since last October and I noticed my pores are smaller and my face is smoother, and my skin toned evened out. I follow Hot and Flashy on YouTube , and pretty much follow her morning and night routine. I don't have any wrinkles but I am getting that hollowness under my eyes. I'm considering getting Juvederm, but I'm scared I may look puffy and bruised afterwards. Aging is so cruel!!!
