Winter Sun Protection: Your Skin Is Still Aging Under the Clouds
The burning rays back off in winter, but the aging-and-cancer rays barely budge — here's why you keep wearing sunscreen.
UVA levels stay relatively steady year-round and pass through cloud and fog, so winter skin keeps aging and building cancer risk even as the UVB that causes visible sunburn declines. The drop in burn risk is what fools people into skipping sunscreen, not an actual drop in damaging UVA.
The Skin Cancer Foundation emphasizes that UV exposure is a year-round concern, not a summer-only one, and advises keeping up daily broad-spectrum protection through the colder months when habits — and sunscreen sales — tend to lapse.
Questions we get a lot
Do I need sunscreen in winter?
Yes, on skin that stays exposed. UVA radiation — the wavelength most associated with skin aging and long-term damage — remains roughly constant through the year and passes through clouds. The Skin Cancer Foundation recommends keeping up sun protection in winter, since lower sunburn risk does not mean lower UV risk.
Why don't I burn as easily in winter if UV is still there?
Sunburn is driven mainly by UVB, and UVB intensity falls in winter because of the sun's lower angle. UVA, however, stays relatively steady and is the bigger driver of aging and cumulative damage. So you can avoid a burn while your skin still takes UVA exposure.
Does snow increase my sun exposure?
It can. Snow is highly reflective and can bounce a significant portion of UV back up at your face and the underside of your chin, areas sunscreen often misses. The Skin Cancer Foundation flags winter outdoor activities like skiing as times to be especially diligent about protection.
