Hi. I'm in my late twenties. I'm really worried about my aging skin as people keep talking that aging sets in once you hit your thirties. I'm about to touch the thirty mark. So I'm extremely worried. While slathering my nightly skincare regime last night, I'm wondering what I can do to prevent the onset of wrinkles? What should i do to fight wrinkles, sagging skin, crow's feet and fine lines. Could somebody help me out with this?
