Understanding UV Damage: Why Year-Round Sun Protection Matters
Sun protection isn’t just for summer. Ultraviolet (UV) radiation affects your skin every single day — rain or shine. Learn how daily habits and the right SPF can prevent premature aging, hyperpigmentation, and long-term DNA damage.
The Science Behind UV Radiation
The sun emits two major types of ultraviolet rays that impact the skin differently: UVA, which penetrates deeply and accelerates aging, and UVB, which causes sunburn and direct DNA damage.
These rays reach your skin year-round — even during winter, on cloudy days, and through windows. This means your skin is constantly exposed to radiation that speeds aging, triggers hyperpigmentation, and increases the risk of skin cancer.
How UV Exposure Affects Your Skin
Collagen Breakdown
UVA rays degrade collagen and elastin fibers, causing wrinkles and sagging over time.
DNA Damage
UVB rays damage DNA at the cellular level, increasing the long-term risk of skin cancers.
Pigmentation Changes
Excess UV exposure triggers melanin production, creating dark spots and uneven tone.
Everyday Habits for Better UV Protection
- Use broad-spectrum SPF 30+ even indoors or in winter.
- Reapply every 2 hours, especially after sweating or sun exposure.
- Wear wide-brimmed hats, sunglasses, and long sleeves.
- Seek shade between 10 a.m. and 4 p.m.
- Use antioxidants to help repair UV-induced oxidative stress.

UV Damage & Sun Protection: Frequently Asked Questions
Do I need protection even on cloudy days?
Yes. Up to 80% of UV rays pass through clouds, meaning your skin still receives damaging radiation.
Do windows block UV radiation?
Glass blocks UVB, but UVA passes through, causing long-term aging and skin damage indoors and in cars.
Is SPF needed in the winter?
Absolutely. UV rays reflect off snow and ice, increasing exposure even on cold days.
What SPF should I use?
Dermatologists recommend SPF 30+ daily for broad-spectrum protection against UVA and UVB.
How often should I reapply SPF?
Every 2 hours, or after sweating, swimming, or towel-drying.
Can darker skin tones be harmed by UV?
Yes. Melanin gives some protection but does not prevent sunburn, hyperpigmentation, or skin cancer.
What’s the difference between UVA and UVB?
UVA ages the skin; UVB burns the skin. Both contribute to long-term damage.
Do I need sunscreen indoors?
Yes, if you're near windows or screens, as UVA can penetrate glass and contribute to skin aging.
Can UV exposure cause hyperpigmentation?
Yes. UV rays stimulate melanin production, creating dark spots and uneven skin tone.
Where can I get dermatologist-recommended SPF?
