My 30th birthday is approaching and looking over some recent photos, I've realized that I don't look as young as I used to. I'm pretty simple (don't wear much make-up) and I've just been using Cetaphil cleanser since junior high. Also moisturizer for the occasional dry patch (mostly in winter.) My skin is oily in summer and dry in winter and still breaks out a little every so often. I've started to notice dark-ish circles under my eyes and the beginning of fine lines.
So.... do I need to start using skin products to slow down the aging process? Any recommendations on products?
