Nowadays, many people have sun spots on their faces, because sun spots are easily seen under the sun. But did you know that if cosmetics are not used properly, they will also cause spots. The spots on the face make us very distressed. Let's listen to the professor's detailed explanation of why sun spots appear on our faces.

Why do we get sun spots on our faces?

As we all know, when the skin is exposed to ultraviolet rays, it will produce a brown pigment called melanin. The original function of melanin is to protect the skin from ultraviolet damage, but when its protective mission is completed, it will become dirt and fall off. When the body's metabolism is not good, some pigments will remain on the surface of the skin and form dark spots.

Inferior cosmetics are rich in metal components, such as lead, mercury and other heavy metals. Most of these chemical components absorb light, which causes skin cells to physiologically release melanin. Melanin can actually effectively absorb ultraviolet rays and reduce the impact of ultraviolet rays on the human body. But in the end, melanin stays on the surface of the skin, forming sun spots, which has a certain impact on people's appearance.

Some people are accustomed to putting skin care products in the back seat of the car when they go out. The high temperature and sunlight will cause the skin care products to deteriorate. If deteriorated products are used, it will also cause sun spots on the skin.

In addition, excessive use of exfoliating products and products rich in salicylic acid, or chemical peeling for whitening, will cause the skin's epidermal stratum corneum to fall off, making it unable to resist the invasion of ultraviolet rays normally, resulting in sun spots and rashes. Therefore, in daily life, we should reduce the use of exfoliating products containing salicylic acid, and we should not do chemical peeling for whitening.

In order to protect your skin from sun damage, you should pay special attention to preventing sunburn in the summer, do a good job of sun protection, apply sunscreen when going out, and it is best to carry a parasol, sun hat, etc. At the same time, you should eat more foods rich in vitamin C to reduce the probability of melanin production.
