Fall into your new beauty routine

Breakouts can increase in the fall because cool air results in dull, dry skin that can trap oil and bacteria, says Renée Rouleau, celebrity facialist and creator of the eponymous skin-care line. Use both a chemical and a physical exfoliant to remove dry skin cells and unclog pores, she says.SHOP NOW: NARSskin Refining Exfoliator, $34

If your skin is oily, trying to dry it up with an astringent can backfire. Too-harsh products cause a buildup of dead skin cells that lead to acne. If you can't give up your toner, then come fall switch to one that’s alcohol free. SHOP NOW: Kiehl's Herbal Alcohol Free Toner, $16

Similar to toners, foaming cleansers can strip moisture from skin, causing dry skin to accumulate and ultimately result in acne. Rouleau suggests using a sulfate-free cleanser in the cooler weather. Sulfates are simply too harsh and will practically strip the water from your face every time you wash.SHOP NOW: Bayberry Pure and Smooth Clay Cleanser, $17

While sunburn-causing UVB rays are less strong in fall, wrinkle producing UVA rays are still just as powerful, says Rouleau. Regardless of the season, be sure to apply a generous amount of sunscreen every day, whether you are inside or out, she says. SHOP NOW: Cane and Austin Protect SPF 55, $38

A moisturizer that you use in the summer might not be hydrating enough for the colder autumn air, says Rouleau. To keep skin healthy, she suggests switching to a more nourishing cream in the coming months.SHOP NOW: Renée Rouleau Hawaiian Nourishing Cream, $70

Like the skin on your face, your scalp also becomes dryer with the drop in temperature. Pasquale Caselle, international educator for IT&LY Hairfashion, suggests adding 20 drops of tea-tree oil to your favorite shampoo and conditioner. This will prevent your scalp from flaking when the season changes and works wonders for dandruff-prone hair as well, he says. You can try this tea-tree shampoo to get a similar effect.

You can bring your minimal makeup look with you from summer to fall. Go for a natural-colored foundation and neutral blush for that less-is-more look, says Linda Caselle, makeup artist for IT&Y Hairfashion (and wife of Pasquale). Ladies with drier skin should use a foundation with moisturizing properties to prevent skin from flaking. SHOP NOW: Mally Face Defender Liquid Foundation, $45

You may no longer lounging by the pool, but that doesn’t mean you have to make peace with pallor. Caselle says to switch to a lighter shade of self-tanner by mixing it with your moisturizer for a lighter application and less streaking. SHOP NOW: Clarins Self-Tanner, $34

Leave the neons and the nail art behind (for the moment!). For fall, try darker metallic shades for a dose of glamour. Caselle says that gray and red metallics are the season’s biggest trends. SHOP NOW: Top Shop Nails in Amethyst, $10; for information on Top Shop stores, call 212-966-9455.

Caselle suggests switching up the way you wear your bronzer. “Use it to contour your face rather than on the apples of your checks and a dusting on your nose, she says.SHOP NOW: Serge Lutens Blusher, $160
