May 23, 2024 · UVA rays are the main type of light used in tanning beds. They can go through windows and clouds. Here are some important facts about UVB rays and how they affect your skin. UVB rays have...

Jul 24, 2023 · ‌UVA and UVB Rays are different types of a form of energy called ultraviolet (UV) radiation commonly seen as sunlight. Both UVA and UVB rays can cause harm to the skin.

The rays that are most damaging to our skin are called ultraviolet (UV) rays. There are two basic types of ultraviolet rays that reach the earth’s surface—UVB and UVA. UVB rays are responsible for producing sunburn.

UV radiation can burn and damage our skin without us ever becoming warm. That’s why it is dangerous even on cloudy days. Not all UV radiation from sunlight makes it to Earth. Most of it gets absorbed by our atmosphere. But two kinds of UV rays do break through. They are called UVA and UVB radiation.

Jul 30, 2014 · What is UV Light? Ultraviolet or UV light is radiation energy from the sun, which comes in two forms: UVA and UVB. UVC radiation, while not originating from the sun, is also dangerous and harmful to the skin. UV radiation is a wavelength too …

Apr 5, 2025 · What is UVA (Ultraviolet A) light? UVA (315-400nm) light has the longest UV wavelength (closest to visible light spectrum) and makes up about 95% of the sun’s UV rays that reach Earth’s surface. A lot of the scientific research …

Sep 22, 2023 · But what’s the difference between UVA and UVB rays—and what impact does that have on your skin and health? Energy from the sun gives us warmth and light. The sun also gives off ultraviolet (UV) radiation that you can’t feel or see.

Mar 9, 2016 · Solar emissions include visible light, heat and ultraviolet (UV) radiation. Just as visible light consists of different colours that become apparent in a rainbow, the UV radiation spectrum is divided into three regions called UVA, UVB and UVC.

UVA rays are a “slow burn,” penetrating your skin more deeply than UVB rays. Prolonged exposure causes genetic damage to cells on the innermost part of your top layer of skin (epidermis), where most skin cancers occur. UVA rays penetrate windows and cloud cover.

Jul 26, 2022 · There are two main types of UV light which reach our skin, UVA and UVB. While these UV rays slightly differ, they both have the potential to cause skin damage. UVA rays have a longer wavelength. These rays penetrate deeply into skin and are primarily associated with aging. UVB rays have a shorter wavelength.
