Have you noticed that even celebs with the most meticulously maintained complexions have failed to take care of their hands?

Typically the last place you worry about applying anti-aging potions and sunscreen, your hands may end up looking rather ravaged once you hit the 40 mark. Think of Madonna and Sarah Jessica Parker -- they've braced every other inch of their bodies against the aging process, but just look at their telltale hands, above.

An article in the Daily Mail points out that veiny, old-looking hands are a dead giveaway for your age. "Dr Patrick Bowler, a cosmetic doctor and medical director of Court House Clinics, explains: 'Ninety-nine per cent of people don't put sunscreen or moisturizer on their hands, but they're so exposed they need as much care as the face, if not more."

"The skin on the back of the hands is very thin and with age it gets even thinner. The subcutaneous fat also disappears, exacerbating the problem, making older hands look bony and veined," says Dr. Bowler.

And all that extra sun exposure can lead to wrinkles, hyperpigmentation and age spots.

So how can you rejuvenate your hands? Dr. Bowler suggests a range of treatments, including fillers like Restylane and Juvederm to plump hands where volume loss is an issue; Intense Pulsed Light (IPL) to erase uneven skin tone and age spots; the Dermaroller -- a medieval-looking device reminiscent of a miniature paint roller studded with tiny needles that prick the skin in order to stimulate new collagen and elastin formation; and glycolic peels to improve skin texture.

If you haven't noticed any of the signs of aging on your hands yet, now's the time to start caring for them just like your face -- they benefit from sunscreen and anti-aging creams just as much.
