When temperatures drop and skies turn gray, sunscreen often slips off our daily to-do list. But here’s the truth: winter sun is still sun.
Ultraviolet (UV) radiation doesn’t take a seasonal break, and melanin-rich skin is not immune to its effects.
There are two primary types of UV rays to consider: UVA and UVB. UVB rays, which are strongest in summer, are responsible for sunburn. UVA rays, however, remain consistent year-round.
They penetrate deeper into the skin, accelerating collagen breakdown, contributing to premature aging, and worsening hyperpigmentation. For Black skin, which is more prone to post-inflammatory hyperpigmentation (PIH), that’s a critical concern.
Melanin does provide some natural protection, estimated at about SPF 13, but it’s not enough to prevent long-term damage. Winter UVA exposure can silently intensify dark spots, uneven tone, and fine lines. Add reflective surfaces like glass windows or even light-colored concrete, and you have indirect exposure that accumulates over time.
Cold air also weakens the skin barrier. Lower humidity levels strip moisture, leading to dryness and micro-cracks in the skin. When the barrier is compromised, skin becomes more vulnerable to environmental stressors, including UV radiation. The result? Increased sensitivity, dullness, and inflammation that can trigger discoloration.
So how do you protect melanin-rich skin during colder months?
First, commit to a broad-spectrum sunscreen with at least SPF 30 every single day, even when it’s cloudy. Broad-spectrum formulas protect against both UVA and UVB rays. For deeper skin tones, opt for sheer, non-chalky formulas that won’t leave a white cast. Gel-based or invisible sunscreens blend seamlessly and layer well under makeup.
Second, layer strategically. Hydration is key in winter, so apply sunscreen after a rich moisturizer to reinforce the skin barrier. Look for ingredients like ceramides, glycerin, and hyaluronic acid to lock in moisture and support resilience.
Third, don’t forget overlooked areas. Ears, neck, and hands are frequently exposed yet rarely protected. If you’re indoors near large windows or driving regularly, daily SPF still applies, UVA rays penetrate glass.
Finally, support your skin with antioxidants like vitamin C in the morning. They help neutralize free radicals generated by UV exposure and enhance your sunscreen’s protective power.
Cold weather may feel less intense, but the sun remains active. Protecting melanin-rich skin in winter isn’t optional, it’s essential for preserving glow, preventing hyperpigmentation, and maintaining long-term skin health.
