In the winter, Canadians naturally spend more time indoors, not realizing that the heating systems that make you feel warm and cozy also dry your skin. To prevent this condition, Dr. Carroll suggests investing in a humidifier for your bedroom. “It will add moisture to dry heated air, infusing it into the skin and helping to combat winter skin signs,” she says.

Even on the coldest days, she encourages people to protect their skin from the effects of sun rays that can cause fine lines and other signs of aging. “We still have quite a few sunny days during winter, and snow and ice reflect UV radiation — so it’s important to keep that defence up against sun damage,” says Dr. Carroll, who advises regularly applying sunscreen with an SPF of 15–30.

Another way to prevent dry skin and decrease aging signs like lines and dull skin is exfoliation, which removes the surface layers of skin. Dr. Carroll recommends Canadian brand Reversa Resurfacing Smoothing Cream and Reversa Skin Smoothing Body Lotion, because they contain 10 percent glycolic acid, a molecule that acts both as an exfoliant and as a water-binding agent that helps to retain moisture into the skin. “These two functions make these products great for winter use,” she says, adding that Resurfacing Face Cream also contains hyaluronic acid, which has excellent hydrating qualities and can hold up to 1,000 times its weight in water.
