We’ve all been told: “Wear sunscreen daily” But do you truly need it on a cloudy day? When you’re inside? During winter? It may seem like common sense overload, but there’s a solid reason dermatologists keep harping on it repeatedly.
First, What Does Sunscreen Do?
Sunscreen shields your skin from ultraviolet (UV) radiation — UVA and UVB rays.
- UVA rays: They age your skin. They get deep into the skin and create wrinkles, dark spots, and loss of elasticity.
- UVB rays: They burn your skin. They cause sunburn and can actually damage your DNA directly.
Both contribute to skin cancer.
Why You Need Sunscreen Every Day
1. UV Rays are Always Present
Even when it’s cold, cloudy, or you’re indoors by the window — UVA rays are still bombarding your skin. They penetrate through clouds and glass. You might not realize it, but the damage is being done in secret.
As much as 80% of UV rays pass through clouds!
2. Indoor Light Can Harm Your Skin As Well
If you spend all day in front of monitors or under fluorescent lights, you’re also emitting blue light and some UV radiation — which can, over the years, contribute to skin aging and discoloration.
3. Everyday Use Protects Against Long-Term Damage
Each day, using sunscreen can:
- Decrease your chances of skin cancer
- Slow premature aging
- Keep dark spots and uneven tone at bay
- Shield sensitive or treated skin (particularly following peels or treatments for acne)
It’s like anti-aging in a bottle — no luxury serum can top the efficacy of SPF.
4. It’s Not Just About the Beach
Some folks only reach for sunscreen when they’re “getting out in the sun.” But you’re still getting exposed if you’re out running errands, strolling to your vehicle, or even sitting by a sunny window.
How to Apply Sunscreen Correctly
- Select broad-spectrum SPF 30 or higher
- Apply daily, even when staying indoors
- Use a nickel-sized amount for your face, and remember your neck, ears, and hands
- Reapply every 2 hours if outdoors, sweating, or in the water
What About Makeup that Contains SPF?
It’s a pleasant bonus, but generally not sufficient. Most folks don’t use enough foundation or BB cream to achieve the stated level of protection. It’s best to use plain sunscreen first and layer makeup over it.
Last Thoughts: Is Daily Sunscreen Really Necessary?
Yes. Definitely. No doubt about it.
If you want to be concerned about your skin’s health, appearance, and future sunscreen should be a part of your daily routine, along with brushing your teeth.
You won’t see the difference immediately, but your future self (and your complexion) will thank you greatly.
