As people get older, their hands will tell their age, even though they may look young. Long-time UV rays exposure will harm the hand skin, causing age spots to appear.
How to avoid age spots? Normally, you can use SPF hand creams to prevent sun damage, and slow down age spots appearing. At a doctor's clinic, you can use lasers to remove age spots.
Other anti-aging methods, such as microdermabrasion, chemical peels or intense pulsed light, can remove the top layer of the stratum corneum, but they also make skin even more vulnerable to sun damage.
