Dark spots, age spots, sunspots, and hyperpigmentation. These are many names for skin brown spots, and what causes one person’s brown spots may have nothing to do with another person. There’s truth behind the term “sunspots,” since sun exposure is the most common cause of brown spots. UVA and UVB rays (two variants of ultraviolet light from the sun) penetrate the skin and increase the melanin production. This is the skin’s method of preventing further damage since melanin absorbs and scatters UV radiation.

That’s why people with darker skin tend to have less sunburn than those with lighter color skin. However, with sun exposure, darker pigment appears and cluster at the skin’s surface, resulting in the appearance of those sunspots.

The sun isn’t the only source of UV radiation. There’s a less-known third type of ultraviolet light known as UVC. Usually scattered by wind and air. Some scientific studies showed that worn-off phosphor coating on fluorescent bulbs produces high levels of UVC that can cause hyperpigmentation after extended exposure. Therefore, it might be wise to use sunscreen if you’re sitting at your desk all day. 

Applying broad-spectrum sunscreen even during the winter before heading outdoors should be a daily habit. The sun’s rays are in fact amplified when there is snow around, causing double the exposure to UV rays as they are reflected off the snow.

People who live at higher elevation, are at higher exposure to UV radiation. It is estimated that forever 1000 feet of elevation, UV radiation increases by 5%. Therefore, sunscreen is recommended during ski trips.
