A day spent in the sun may feel good for the soul—but not your skin.

“It’s extremely important for men to take care of their skin in the summer because the warmer weather leads to more sweating when exercising,” says dermatologist and Dove expert Terrence Keaney, M.D. “Sweat and friction can lead to irritation, especially in the skinfolds, such as the underarms.”

And then there’s sunburn, chapped lips, and oily skin. And while these issues are top of minds during the warmer months, the winter sun could also lead to a host of problems if you’re not taking care of your skin, too. If you’re someone who liked to snowboard or ski, your proximity to the sun puts you at a heightened risk of UVB rays—the main cause of sunburn and skin damage, according to the Skin Cancer Foundation.

You might be asking yourself, “Why should I care about my skin?” For one, happy skin means healthy skin. If you’re not looking out for your body’s largest organ you might be leaving yourself susceptible to conditions like skin cancer that, while treatable, can be pretty serious.
