I remember my last visit to my dermatologist: He said, if you wanna stay looking young, do three things: Sunscreen faithfully, moisturize, and retin-A around your eyes at night. I'm 42.
If retinols irritate your skin, Kiehl's brand skin care makes a great 11% Vitamin C cream called Powerful-Strength Line Reducing Concentrate. I am mixed race, but this gave my skin an over all smoothness, healthy glow, and firmness. Vitamin C is believed to do the same as retinols, but gentler. I don't really have a problem with lines as yet, but I do have two of them at the corner of my left eye. You can check this product out online or in store. They have great moisturizers too.
Hope this helps.
