Time to scrub in.

Come January, even your complexion wants a fresh start: Out with the old (and dull), in with the renewed. The quickest way is to add an effective exfoliant to your weekly routine. Not only will it leave behind a softer surface, but it will also help your serums, creams, and makeup be absorbed better. There are two kinds of exfoliant: Physical, which manually brush away dead cells using gently abrasive ingredients or fibers; and chemical, which enlist natural acids and enzymes to dissolve them. Look for finely milled natural ingredients, like rice and sugar, that easily dissolve in water. Steer clear of microbeads, the mini plastic spheres once common in scrubs. They can pollute waterways, and though they were banned in the U.S. in 2017, they still linger under aliases like "polyethylene."

Here's a range of options to use at home, depending on your skin type and preference.

For Mild Buffing

If you have sensitive skin, a warm cotton washcloth and cleanser, massaged in circles, are the gentlest option. These polishers go easy on irritable skin and darker complexions, which are prone to discoloration from too much friction, says Ronda Farah, an assistant professor of dermatology at the University of Minnesota.

For those who prefer a physical exfoliator, look for a scrub with a soft grit made of fine or soluble ingredients. (Dermatologist Neal Schultz warns against sharp, coarse ones like ground nut shells, which can cause small tears in the skin.) "Poppy seeds, pomegranate-seed powder, and very fine sugar are great," says dermatologist Shereene Idriss. L'Oreal Paris Pure-Sugar Scrub Resurface & Energizeand Olay Regenerist Detoxifying Pore Scrub are two good options. Interested in trying a chemical exfoliator? Fruit enzymes and lactic acid dislodge old skin by gently breaking down the binders between dead cells and new ones. Lactic acid, an alpha hydroxy acid (AHA) derived from sour milk, has moisturizing qualities, so it's soothing, too. We like Naturopathica's Sweet Cherry Brightening Enzyme Peel.

For Moderate Sloughing

Normal to oily types can handle stronger products, but stop if you notice intense stinging or dryness. Use them at night, starting at once a week, and be sure to wear SPF the next day.

With light pressure, electricbrushes disrupt dead cells stuck in pores and fine lines, making them a great physical exfoliator. "Look for one that wiggles back and forth rather than spinning around; it's less likely to irritate," says Carolyn Jacob, a Chicago dermatologist. The Clarisonic Mia Smart is a great option. On the chemical front, you'll want something with glycolic and salicylic acids (AHAs and beta hydroxy acids, or BHAs, respectively), which go deeper into the skin than lactic acid. They differ in strength, so start once per week and increase frequency gradually. (Pads are also a good bet-the premeasured ingredients prevent overapplication, says Connecticut dermatologist Mona Gohara.) Tingling is a normal side effect. Drunk Elephant T.L.C. Sukari BabyFacial and Peter Thomas Roth Professional Strength 40% Triple Acid Peel are our top picks.

Go Pro

The strongest treatments are performed by a doctor. They penetrate farther into skin than topical options, and over time can smooth bumps, diminish discoloration, help treat fine lines, and zap acne. Make sure to have them done by a board-certified dermatologist, or an aesthetician working under the guidance of one. Microdermabrasion is when a doctor uses a tool to sand away dead skin, which causes tiny bits of injury that spur cell production, according to Jacob. The tips vary in coarseness, and some new devices spray fluid to hydrate newly exposed skin. You might feel slightly sunburned for a day or two afterward. Dermaplaning is another option. During this treatment, an expert uses a blade to shave off facial fuzz-plus a layer of fading cells. The upshot: velvety skin with no downtime.

In-office peels are treatments worth considering, too. A chemical solution containing high doses of AHAs and BHAs is applied for several minutes, then removed. Results depend on strength, but they eventually make skin radiant and smooth. Post-peel redness lasts from a few hours to a few weeks. And, if you're ready for something a little more advanced, fractional lasers deliver serious results. In fact, they're the most efficient way to buff skin and kick-start collagen production, but that also means they require the most downtime. The most common ones, like Fraxel, send light into skin to trigger the wound response, cuing a surge in cell production. Expect swelling and redness for a day or two, and peeling on dark spots for about a week before resurfaced skin makes its debut.

Dry Brushing 101

Last but not least, you can consider dry brushing. Certain claims about this practice are highly suspect (flushing out toxins and erasing cellulite? not exactly), but experts stand by it as a pre-shower exfoliator for your arms, legs, and body. The bristles gently stimulate the skin, which increases blood flow, Jacob says, and the extra circulation can even be energizing. Brush up to once a day, using long, light strokes and avoiding cuts or irritated areas.
