Introduction
Sunscreen in November? Absolutely. While it might feel unnecessary when skies are gray and temperatures drop, UV rays are still at work—affecting your skin’s health every single day. Here’s why SPF belongs in your winter routine just as much as in July.
UVA vs UVB: The Winter Truth
UVB rays (responsible for sunburns) may decrease in winter, but UVA rays (which cause premature aging and penetrate glass) remain constant year-round. These rays can harm your skin even on cloudy, cold days.
What Happens If You Skip SPF in Winter?
You’re exposing your skin to damage that leads to fine lines, dark spots, and weakened barrier function. This is especially risky if you’re using retinol or exfoliants, which make skin more UV-sensitive.
Best Sunscreen Types for Winter Skin
Opt for hydrating formulas with added ceramides or hyaluronic acid. Mineral sunscreens with zinc oxide or titanium dioxide are gentle and offer broad-spectrum protection.
SPF and Moisturizer Combos: Are They Enough?
A moisturizer with SPF is convenient, but not always enough. Aim for SPF 30 or higher, and reapply if you’re outdoors or near windows for extended periods.
Everyday Habits for Year-Round Protection
- Apply SPF every morning, even indoors
- Don’t forget ears, neck, and hands
