How can I protect my skin from UV light?
Sunlight is vital for our health—it helps our bodies produce vitamin D and boosts our mood. However, too much exposure to ultraviolet (UV) light from the sun or artificial sources (like tanning beds) can seriously damage your skin. From premature aging to an increased risk of skin cancer, UV rays should not be underestimated.In this blog, we’ll walk you through simple and effective ways to protect your skin from UV damage and keep it healthy all year round.
Ultraviolet radiation is a form of energy that the sun produces. UV rays are invisible radiation from the sun. The UV energy that the sun produces reaches the Earth and provides vitamin D for your body to help you survive. You can also find UV radiation in human-made sources like tanning beds.
There are three types:
leads to skin cancer. Penetrates deep into the skin and contributes to aging and wrinkles.UVB: UVB can damage the outermost layers of your skin. It can cause sunspots, tanning, sunburns, and blistering, which can lead to skin cancer.
1.UVC: Mostly absorbed by the ozone layer and doesn’t reach the Earth.UV radiation accelerates the ageing process of the skin. It breaks down the collagen and elastin fibers that maintain the skin’s elasticity and strength, leading to premature wrinkles, age spots, leathery skin, and other signs of ageing, a process known as photoaging.

How can I protect my skin from UV light?
1. Apply Sunscreen Every Day
Sunscreen isn’t just for beach days—it’s a daily necessity.
Don’t forget ears, neck, hands, and feet—these are often missed!
Use a broad-spectrum sunscreen with at least SPF 30.
Apply it 15–30 minutes before going outside.
Reapply every 2 hours, especially if you’re sweating or swimming.
2. Wear Sun-Protective Clothing
When spending time outdoors, clothing is one of the simplest ways to protect your skin from harmful UV rays. However, not all fabrics offer the same level of protection. If you can see light through a material, UV rays can also pass through. Long-sleeved shirts, long pants, or long skirts cover more skin and are therefore more protective. Dark colors generally block more UV radiation than light colors, and tightly woven fabrics are better at shielding than loosely woven ones. Dry fabrics also provide greater protection than wet fabrics.
For enhanced safety, consider clothing with a UV Protection Factor (UPF) rating. UPF garments are designed to block UV rays effectively, even when wet. They are often made from tightly woven fabrics and may have special coatings to absorb harmful radiation. A higher UPF number means greater protection—values typically range from 15 to 50+, with 50+ offering excellent defense.
Additionally, certain laundry detergents can boost the UV protection of clothes you already own by adding microscopic crystals to the fibers. While these may help, the exact level of added protection is unclear.
Combining sun-protective clothing with sunscreen and shade is the best strategy to keep your skin safe from UV damage.
Covering your skin is one of the most effective ways to block UV rays.
- Choose long sleeves, pants, and wide-brimmed hats.
- Look for clothes with UPF (Ultraviolet Protection Factor) labels.
- Tightly woven fabrics offer better protection than loose, thin ones.
3. Use UV-Blocking Sunglasses
UV-blocking sunglasses protect both your eyes and the delicate skin around them, reducing the risk of eye diseases, including possible eye cancer. Choose sunglasses that block 99%–100% of UVA and UVB rays — check the label for phrases like “UV absorption up to 400 nm” or “Meets ANSI UV Requirements.”
- Darkness of the lens doesn’t mean better protection — UV defense comes from a special coating, not lens color.
- Large or wraparound styles offer better coverage from different angles.
- Give children real UV-protective sunglasses, not toys.
- Some eyeglasses and contact lenses have UV protection — confirm before assuming. Contact lenses alone aren’t enough since they don’t cover the whole eye area.
4. Seek Shade Whenever Possible
Avoid direct sun exposure, especially during peak hours (10 AM to 4 PM).
- Sit under umbrellas, trees, or canopies when outdoors.
- Even in the shade, continue to wear sunscreen—UV rays can reflect off surfaces like water, sand, and concrete.
5. Check the UV Index Daily
Before you go outside, check the UV Index for your area.
- A UV Index of 3 or higher means you need sun protection.
- Many weather apps and websites show this information.
6. Avoid Tanning Beds
Tanning beds are not a “safe” way to tan. They emit high levels of UVA rays, increasing your risk of:
- Skin cancer (especially melanoma)
- Premature aging (wrinkles, leathery skin)
- Eye damage
7. Watch Out for UV-Sensitizing Products
Some medications and skincare products make your skin more sensitive to sunlight.
- Common examples include antibiotics, acne treatments, and certain herbs like St. John’s Wort.
- Read product labels and consult your doctor if you’re unsure.
Protect children from the sun
Children often spend more time outdoors than adults and are more prone to sunburn. Regardless of skin color or tone, they need extra care in the sun. Focused on play, they may not notice how long they’ve been exposed or understand the risks of UV damage.
Parents and caregivers can protect children by following key steps: seek shade, dress them in protective clothing, apply and reapply sunscreen, and use a wide-brimmed hat and UV-blocking sunglasses. Aim to protect them as fully as reasonably possible.
Babies younger than 6 months should be kept out of direct sunlight. Use hats, stroller covers, umbrellas, and lightweight protective clothing. Many experts recommend avoiding sunscreen for infants this age—check with your baby’s doctor about whether sunscreen is appropriate, and which type or brand is safest if needed.
Early sun protection helps prevent sunburn now and reduces the risk of skin damage and skin cancer later in life
