Glowing, glowing, gone: Where, oh where, has your radiance gone? In your 30s your skin's inner light appears to dim. You might not consider it a sign of aging, but diminished color, rougher texture, brown spots, and uneven tone is the classic first sign. What's to blame: a slowdown in oil production and cell turnover. (It now takes longer for fresh cells to reach the surface.)
The first sprinkle of wrinkles: The reasons for those new crow's feet are twofold, says Steven J. Pearlman, MD, a New York City plastic surgeon. First, the thin skin around your eyes produces less moisture than the rest of your face, so it's extra-vulnerable to sun exposure. Second, the years spent blinking, squinting, and making faces eventually leave their mark. Expression lines may pop up on your forehead and around your mouth, too.
