Do We Need SPF in Winter?
It’s tempting to stash away your suncream when the chill of winter sets in. With shorter days, cozy layers and fewer glimpses of sun, SPF might seem less necessary. But even on overcast days, up to 80% of UV rays can penetrate clouds, quietly causing skin damage over time.
Whether you’re indoors by a window or outside in the cold, your skin is still at risk. So, is it really safe to skip?
Why Is SPF a Must, Even When the Sun Isn’t Visible?
The sun doesn’t take a holiday in winter. UVA rays, the main culprit behind premature aging, pigmentation, and long-term skin damage, remain just as potent in December as they are in July. Unlike UVB rays, which are stronger in summer, UVA rays penetrate clouds, glass, and even deeper layers of the skin, as stated by the Skin Cancer Foundation. This means your skin is exposed and vulnerable whether you’re outdoors on a cloudy day, commuting by car, or sitting by a sunny window - causing harm all year round!
For winter sports enthusiasts, the stakes are even higher. Snow and ice don’t just sit passively - they act as mirrors, reflecting up to 80% of UV rays back onto your skin and effectively doubling your exposure. This means that whether you're skiing down slopes, taking a hike through snowy trails, or simply strolling on an icy morning, the sun's rays are reaching you from every angle. Without SPF, your skin remains vulnerable, even in the coldest conditions. In short, SPF isn’t just for sunny days - it’s a daily essential for protecting your skin (1).
Why SPF Is Non-Negotiable for Healthy Skin
Protecting your skin isn’t just about avoiding a summer sunburn. Here's a simple breakdown of the key players:
UVA Rays: Cause aging by breaking down collagen and triggering fine lines, wrinkles, and sunspots.
UVB Rays: The primary cause of sunburn and a major risk factor for skin cancer.
Consistent SPF use offers a host of long-term benefits:
Prevents Premature Aging: Keeps skin smooth and youthful.
Reduces Skin Cancer Risk: Protects against harmful cellular changes.
Promotes Even Skin Tone: Shields from pigmentation issues.
Even if you’re spending most of your day indoors, SPF acts as a daily defense, protecting your skin against the damage you can’t see.
Mineral vs. Chemical Sunscreams
Mineral Suncreams:
How they work - Sit on top of the skin and reflect UV rays
Key Ingredients - Zinc oxide, titanium dioxide
Best for - Sensitive or acne-prone skin.
Chemical Suncreams
How they work - Absorb into the skin and convert UV rays into heat
Key Ingredients - Avobenzone, oxybenzone, octisalate.
Best for: - Lightweight feel and invisible finish.
Where Does SPF Fit in My Routine?
For me, SPF is a non-negotiable final step in my morning skincare routine. After cleansing, moisturising, and applying any serums, I make sure to smooth on a layer of sunscreen (SPF 30 or higher). It’s my daily armor against the sun’s rays, no matter the season. On some days, I’ll follow this with makeup, starting with primer or foundation. But most days, I skip the foundation entirely and let my SPF do the work. A good suncream often gives my skin a natural, dewy glow, and paired with just a touch of mascara, it’s all I need for a fresh, minimal look. It’s proof that protecting your skin doesn’t have to compromise your style - it can enhance it.
