UV rays from the sun are the number-one cause of skin aging. You probably already know this, which is why you regularly use sunscreen in the summer. But what about during the winter months? Do those gray days and thick clouds change your skin care routine?
Winter sun can create lasting damage to your skin.
Why Winter Protection is Important
Even during the cold weather, we’re at risk from ultraviolet radiation in the form of UVA rays. Though UVB radiation decreases, UVA radiation does not and it’s actually these rays that are more responsible for premature aging. They reflect off snow and can pass through glass. They’re not affected by changes in temperature, and can penetrate deeply into the skin, where they may create damage that leads to aging and even increases risk of skin cancer. They’re also more potent at higher altitudes—take note, skiers!
Even just a few minutes of exposure every day over many years can cause noticeable changes in your skin. These include:
- Age spots and hyperpigmentation
- Spider veins
- Rough and leathery skin
- Fine lines and wrinkles
- Sagging and bagging
- Blotchy complexion
- Dullness and dryness
To retain more of your youthful complexion, try these tips for protecting your skin from winter sun damage.
- Use a safe sunscreen. Choose one that’s rated at a 30 SPF or higher, and that includes zinc oxide or titanium dioxide. Refer to the Environmental Working Group’s safe sunscreen chart for help.
- Avoid tanning beds. They are just as dangerous and sometimes even more damaging than real sun. An international study in 2006 found a strong association between tanning bed use and risk of skin cancer. Based on 7 worldwide studies, people who first used a tanning bed before the age of 35 increased their risk for skin cancer by 75 percent.
- Wear good sunglasses. The signs of aging tend to appear first around the eyes. Protect them with quality sunglasses that have UV coating on the lenses, and that are large enough to cover some skin around the eyes. Look for a tag that says the sunglasses block 99-100 percent of UVA and UVB rays, and make sure they fit well so they don’t slide down your nose.
- Don’t forget the lips. The lower lip receives a greater amount of exposure than the upper lip, and winter chapping can leave it more vulnerable to UV damage. Find a lip balm that contains a safe sunscreen to protect your lips. Avoid shiny lip glosses when out in the sun—they may attract more light to your lips, which can increase damage.
- Boost internal protection. Fruits and vegetables are high in antioxidants, which help fight free radicals and sun damage. Sugar and processed foods, on the other hand, can increase inflammation, which can make sun damage worse. Boost your intake of healthy foods to give your skin the edge it needs to deal with winter conditions.
- Bundle up. Hats, gloves, and scarves are indispensable in winter. Even if you don’t see blowing snow, a scarf can help protect your skin from cold, dry air as well as from the wind and sun. If you have sensitive skin, avoid those made with wool, as it can be irritating.
