On a cool, gray February day, sunscreen may be the last thing on your mind. Many people think of it as a summer product, packed in a beach bag and forgotten until June. But many dermatology organizations, including the American Academy of Dermatology, recommend using sunscreen year-round on skin that will be exposed to the sun.
This is general information. For personal skincare advice, especially if you have a skin condition or concerns about sun exposure, talk with a dermatologist.
The Sun Is Still Shining
Even when the air is cold, the sun’s ultraviolet light still reaches the earth. UV light comes in two main types that affect skin: UVA and UVB. UVB is more closely associated with sunburn, and its intensity varies with the season. UVA is present throughout the year and can pass through clouds and glass windows.
That means time outdoors on a cloudy day, sitting by a sunny window or driving can all involve some sun exposure.
Choosing a Sunscreen
When choosing a sunscreen, many dermatologists suggest looking for:
- Broad-spectrum protection, which means it is designed to protect against both UVA and UVB
- An SPF of 30 or higher for daily use
- A formula you actually enjoy wearing, since you are more likely to use it
There are two main types: mineral sunscreens, which use ingredients such as zinc oxide or titanium dioxide, and chemical sunscreens, which use other ingredients that absorb UV light. Both can be effective. People with sensitive skin sometimes prefer mineral formulas, but everyone is different.
Making It Part of Your Routine
The easiest way to use sunscreen consistently is to make it part of your morning routine:
- Cleanse your face.
- Apply moisturizer.
- Apply sunscreen as the last step before makeup.
Some moisturizers include SPF, which can simplify the routine. Remember your ears, neck and the backs of your hands, which are often exposed.
Reapplication
Sunscreen labels typically recommend reapplying at least every two hours when you are outdoors, and more often if you are sweating or swimming. On a winter day spent mostly indoors, your needs may be different. Follow the directions on your sunscreen’s label.
Beyond Sunscreen
Sunscreen is one part of sun care. Other simple habits include:
- Wearing a hat and sunglasses outdoors
- Seeking shade during the brightest part of the day
- Wearing lip balm with SPF
A Year-Round Habit
Building a sunscreen habit in winter means you are already in the routine when spring arrives. Keep a bottle by the bathroom sink, a small tube in your bag and another in the car. Like brushing your teeth, it soon becomes something you do without thinking.
If you notice any changes in your skin, such as new spots, changing moles or patches that do not heal, see a dermatologist or your doctor. Regular skin checks are an important part of caring for your skin.
