Now that winter is in full swing, skin issues such as dryness and acne worsen for many. Here's how to keep your skin stable throughout the cold-weather months.

"Cleanse, Treat, Moisturize, Protect"
"Cleanse, Treat, Moisturize, Protect" is the four-step basis of the skincare regimen advocated by leading dermatologists. A cleanser is a product used to remove dirt, oils, makeup, sunscreen, dead skin cells, and fine particles caused by air pollution naturally accumulated by the skin each day. You may refer to it as "face wash" or "soap." A treatment is any product formulated to combat a specific skin concern such as fine lines, acne, or sun damage. A moisturizer, or lotion, is used after cleansing and treating to keep the skin hydrated. Finally, to protect means to use a product containing SPF, often sunscreen, to shield the skin against harmful ultraviolet rays emitted by sunlight. Though this four-step routine works effectively year-round, it is critical in winter to use the right products for your skin type throughout each step, as skin reacts to changes in temperature and humidity.

"Cleanse, Treat, Moisturize, Protect" is the four-step basis of the skincare regimen advocated by leading dermatologists.
Step One: Cleanse
Step One: Cleanse. Humidity levels tend to drop during colder months as the air holds less moisture. The skin often reacts to dry weather by overproducing sebum, the natural oils secreted by sebaceous glands in the skin. The increased sebum can lead to unwanted breakouts of whiteheads (pimples) and blackheads. While your first thought may be to reach for a cleanser that combats acne, this could be counterintuitive as many acne-eliminating facial washes contain active ingredients such as salicylic acid (HOC6H4COOH), hydroxy acids (RCH(OH)COOH), and benzoyl peroxide compounds (C14H10O4) that further dry out the skin. Therefore, the better choice is to use a more gentle cleanser without such active ingredients to remove impurities without stripping the skin of moisture.

Top Pick: The Inkey List Oat Cleansing Balm contains oat (Avena sativa). Oat possesses avenanthramides, phenolic alkaloid antioxidants that moisturize the skin and soothe irritation.

Step Two: Treat. Fall and Winter often highlight two major skincare concerns: Dry, flaky skin and acne caused by sebum overproduction. For dehydrated skin, a serum containing hyaluronic acid (C33H54N2O23), squalane (C30H62), or snail mucin can lock in hydration and protect the skin's moisture barrier. For acne, a cream containing retinol (C20H3O) or a toner containing lipohydroxy acid (C30H40O8) will combat unwanted breakouts and dark spots caused by previous blemishes through their resurfacing qualities and their ability to lift dead skin.

Top Pick (Dryness): The Ordinary Hyaluronic Acid 2% + B5 Hydrating Serum is a hygroscopic (water-absorbing) serum that helps skin retain moisture, even in dry conditions.
Top Pick (Acne): SkinCeuticals LHA Toner employs Lipohydroxy acid to exfoliate the skin, removing dead skin cells to reveal blemish-free skin through consistent use.


Step Three: Moisturize
After cleansing and treating, use a thick, dense facial cream to hydrate your skin and create a barrier between your skin and the environment. A good moisturizer will also keep the rest of your skincare routine in place. You won't have to be as picky when choosing a moisturizer, but make sure it is non-comedogenic (will not clog pores).

Top Pick: COSRX Advanced Snail 92 All-in-One Cream contains 92% snail mucin (cryptomphalus aspersa). While it sounds gross, snail secretion filtrate contains glycoprotein enzymes that repair and soothe sensitized skin, a condition that worsens in dry winter months.

A common misconception is that SPF, or sunscreen, is unnecessary in colder months. However, harmful ultraviolet rays can penetrate the skin year-round if not protected against. The American Academy of Dermatology also recommends using a non-comedogenic mineral sunscreen (rather than a chemical sunscreen) for those with sensitive or acne-prone skin to avoid breakouts.

Top Pick : Sun Bum Mineral SPF 50 Sunscreen Lotion - Fragrance-Free checks all the boxes. As the name suggests, it's mineral and fragrance-free, which means it won't irritate sensitive skin or cause unwanted breakouts while protecting your skin from UV damage.


Takeaway
There's no end-all-be-all to skincare. Perfecting your routine can take months if not years. However, with increased knowledge about the effects of skincare ingredients and chemical compounds, you can feel confident that you have control over your skin, even if you can't control the weather.
