With cold weather comes dry air and seriously chapped skin that you need to exfoliate. Even worse, the aging process dries skin and reduces cell turnover, leaving a thin layer of dead skin cells on the surface of your skin. What is every dermatologist's answer to these dull skin woes? Exfoliation. However, gone are the days of rough, sandpaper-like scrub that left skin irritated and raw. Sophisticated formulations of gentle physical and chemical products can now deliver twice the results in half the time of old-school scrubs.

What Does Exfoliate Mean?
Physical exfoliants remove the surface layer of dead cells from your skin by means of a granule, brush or blade. Traditional scrubs include physical exfoliants as well as electric skin brushes, abrasive cloths, dermablades and razors.

Physical exfoliants are incredibly effective, but you must be careful to choose quality products and tools to avoid micro-tears in the skin, which can leave skin susceptible to dullness and fine lines.

Chemical exfoliation, on the other hand, uses acidic ingredients to dissolve dead cells on the surface of the skin. While physical exfoliation is recommended only once or twice per week, you can exfoliate with chemical products daily. Keep reading for top picks to exfoliate every part of your body.

How to Exfoliate Your Face
The products used to exfoliate your face should be extremely gentle as this skin is most susceptible to damage and tearing. Fresh Sugar Face Polish, $62, has a cult following for brown sugar's ability to buff away dry skin. Plus, vitamin C and beautifying oils give the fresh skin a dose of moisture for the ultimate glow.

Alpha hydroxy acids (AHAs) and beta hydroxy acids (BHAs) are the best chemical ingredients for dull, dry skin. Look for an option like Murad Age Reform AHA/BHA Exfoliating Cleanser, $38, which contains these potent acids to dissolve dead skin. Some reviewers saw smoother skin with just one application.

Your body can handle a rougher scrub than the skin on your face. Coffee granules deliver a deep scrub, and caffeine is known to brighten skin and deliver a glow. Frank Body Original Coffee Scrub, $16.95, goes a step further by offering ingredients like almond oil for moisture.

If you suffer from body acne or rough skin on your upper arms, go for a lotion with BHA. Paula's Choice Resist Weightless Body Treatment 2% BHA, $26, will exfoliate those trouble spots in no time.
