FAQ about uv light

What are the different types of UV rays?

There are three types of UV rays: UVA, which are responsible for skin ageing, UVB, which cause sunburn, and UVC, which are blocked by the Earth's atmosphere.

How to protect oneself from UV rays?

To protect oneself from UV rays, it is advised to wear broad-spectrum sunscreen, protective clothing, a hat, and sunglasses, and to avoid the sunniest hours of the day.

Do clouds block UV light?

No, up to 80% of UV rays can penetrate through clouds, which is why it's crucial to protect oneself even on cloudy days.

Are children more vulnerable to UV rays?

Indeed, children's skin is more sensitive to UV rays which makes them more susceptible to sunburn and long-term damage.

Do windows block UV rays?

House or car windows block the majority of UVB rays, but allow a significant amount of UVA rays to pass through, hence the importance of wearing sun protection, even indoors.

Does UV light exclusively cause skin cancer?

UV rays are primarily responsible for skin cancers, but they can also damage the eyes and increase the risk of cataracts.

Does tanning protect against UV rays?

Tanning is primarily a skin defence reaction against the damage caused by UV rays. It does not protect against the long-term effects of ultraviolet radiation.

Is the sun beneficial for acne?

While the sun may temporarily improve acne, prolonged exposure often exacerbates inflammation and promotes the appearance of scars.

What are the risks of prolonged exposure to the sun?

Extended and/or repeated exposure to the sun can lead to sunburn, premature skin ageing, pigmentation spots, and an increased risk of skin cancers.

Can sun exposure trigger allergies?

Yes, some individuals develop reactions such as summer light eruption or phototoxic rashes following sun exposure.
