1. 雙手
Always exposed to the elements, your hands probably give away your age more than any other body part. Experts say sun damage is the biggest culprit. As a result, you should apply sunscreen to the backs of your hands, in addition to a good hand cream at least once a day. According to one expert, it's important to keep your hands well moisturized with thick creams -- particularly overnight. And the sooner you establish a daily regimen the better. Even though hands usually start looking older in one's 20s, most people don't recognize the signs of aging until their 30s or 40s, and most people won't start changing their routines until they notice the appearance of serious aging signs.
