This Winter, Guard Against Melasma with Smart Sun Protection

We talk a lot about skin cancer risks in winter, thanks to environmental and behavior changes that up the stakes. But winter sun exposure doesn’t just put you at risk for skin cancer—it’s also a big trigger for melasma, a stubborn brown discoloration that primarily affects women and is notoriously hard to treat. Taking sun protection seriously this season can keep melasma from making an unwanted appearance.

Why Did I Get Melasma?

More than 90% of melasma cases affect women, but it’s not fully understood why men are rarely affected. While genetics can play a role, the biggest factor is environmental exposure, specifically, the sun—no matter the season.

When melasma shows up, it typically darkens areas like the face, neck, shoulders, and forearms. These spots may also be a reaction to hormonal changes, such as those from birth control or pregnancy, which affects 15–20% of pregnant women.

The most likely culprit behind melasma? Too much sun. UV rays, heat, and light activate melanocytes, which produce melanin in excess, causing those noticeable dark patches.

Sunscreen to the Rescue

Believe it or not, you can help prevent melasma, skin cancer, and aging in just one minute a day. That’s all it takes to apply sunscreen to your face, neck, arms, and hands.

Add Visible Light Protection

If you’re already consistent with sunscreen, you deserve a high-five! But there’s one more player to know about: Visible Light.

Visible Light, like UV rays, comes from sunlight and indoor sources like screens. While we know UVA and UVB rays cause aging and burns, Visible Light poses its own risks. Studies reveal that it can intensify melasma, dark spots, and pigmentation, especially for deeper skin tones. The catch? Most sunscreens don’t block Visible Light.

The Solution: Tinted Sunscreen

Tinted sunscreens are formulated with mineral filters like zinc oxide and tinted pigments to block UV and Visible Light. Medical-grade options like Elta MD and SkinBetter Science offer tinted, tone adaptive shades that provide thorough daily protection.

Adding tinted sunscreen to your routine can make a noticeable difference. For professional-grade options, purchase at any Midwest Dermatology office location or visit our online store at midwestderm.com.
