What are the causes of sunburn? Sunburn caused by sunlight

The main cause of sun spots is excessive exposure to ultraviolet rays from the sun, which is photoaging caused by sunlight. There are also other rays, such as fluorescent rays, which can damage the skin and cause sun spots. Here are some specific causes of sunburn.

What are the causes of sunburn?

Sunburn caused by sun exposure

Generally, after being exposed to the scorching sun, the damaged skin will show visible and clear red spots within a few hours. Depending on your skin type and the damage done to your skin by the sun, the spots may appear in different colors, ranging from light red, red, or even dark red. There may be slight bumps, which are initially oval in shape, but after a few days turn into scattered brown patches. Sunburn doesn't just appear on the face; it can also occur on the exposed skin on the arms, thighs, and back.

Poor quality cosmetics cause sun spots

Cosmetics contain many metal ingredients - some people use skin care products containing many chemical metal ingredients such as lead and mercury or with added fragrances for a long time. These chemical ingredients have light-absorbing effects and can easily cause black spots on the skin. In addition, some people do not know that these products can easily deteriorate at high temperatures, and they often leave their skin care products in the back seat of the car when they go out. After using deteriorated products, their skin will become itchy and will develop spots when exposed to light.

Sunburn caused by excessive chemical peeling

In order to whiten their skin, some people usually do some chemical peeling to remove the skin's epidermal stratum corneum, thinking that the more they do it, the better. In fact, if they do it too frequently, the skin will become more sensitive to light and become drier. Rash will occur immediately after being exposed to the sun, and pigmentation will become more serious than before.

At present, the main cause of sunburn in most patients may not be the single factor of sunlight and ultraviolet rays, but because the long-term use of cosmetics containing many metal ingredients has caused certain damage to the skin, resulting in a decrease in the skin's resistance and a disorder in the skin's metabolic capacity.
