When the temperature drops and the heat is on full-blast, your skin suffers. Dry air pulls moisture from your skin, which can compromise the skin's barrier function -- its main protection against pollutants, allergens, UV and other skin irritants. The result: super-reactive and irritated skin.

To keep your skin's barrier intact (and ward off itchy, dry skin), switch to a heavy-duty moisturizing routine, like the Dr. Jart+ Ceramidin line. The Ceramidin Liquid and Cream are intensely moisturizing and packed with ceramides that deliver moisture deep into your skin.

To cover up any redness or rosacea brought on by winter winds, try La Roche-Posay Rosaliac CC Cream, a new product specially formulated to reduce redness over time. It contains ambophenol, derived from a plant in Madagascar, which has been clinically proven to reduce redness caused by rosacea. Plus, it's got SPF 30, so you don't have to worry about the sun aggravating your skin.

Many ingredients in acne products are already drying and irritating. Add a temperature dip to the mix and you've got a recipe for a flaky disaster. Instead of relying on spot treatments and oil-absorbing masks, try getting your acne treatment in with a wash-off cleanser, like Renee Rouleau AHA/BHA Cleansing Gel -- a deep-cleansing but non-drying wash with gently exfoliating jojoba beads.

If the fine lines around your eyes are looking a little deeper in the harsh glare of the winter sun, it's probably because your skin is dehydrated -- that, plus all those hours spent inside squinting at your Netflix du jour are taking their toll. For serious plumping power, try Volante Skincare Transformative Eye Crème, a botanical-based product with skin-lightening peptides and light-diffusing ingredients to minimize crow's feet.

Now is not the time to rely on an oil-absorbing charcoal or clay mask. Instead, pile on a nourishing mask like Dermalogica Skin Hydrating Masque a few times a week. The moisturizing mask contains hyaluronic acid to hydrate skin, while tomato seed lipids restore the protective barrier.

A steamy shower is tempting when you're chilled to the bone, but it's also the culprit behind itchy, flaky skin during the winter months. Keep it lukewarm and under 10 minutes to avoid stripping your skin of essential oils. Body soap that leaves you squeaky-clean is great for removing sweat and grime during warmer months, but in the winter, you need something gentler. Try a product like Dove Deep Moisture Body Wash. Its creamy, rich lather leaves skin feeling clean, while ingredients like soybean and sunflower seed oil keep skin supple.
