Will sunburn on the face cause acne? Does ultraviolet light sterilization help to remove acne?

The most common skin disease in the hot summer is sunburn. Especially for those ladies who love beauty, sunburn is something they cannot accept. Sunburned skin is red and swollen, which is very uncomfortable. Some people also report that they are prone to acne when exposed to the sun. What’s going on? Will sunburn on the face cause acne?

Will sunburn on the face cause acne?

Sunburn on the face may cause acne. When the skin is exposed to the sun, it secretes a lot of oil, and ultraviolet rays can cause the stratum corneum to thicken. If it is not cleaned in time, the oil will clog the pores, causing acne. Especially for those who already have acne, it may even get worse. Excessive exposure of the skin to ultraviolet rays can cause post-inflammatory pigmentation in the inflamed areas, making the acne and acne marks on the face darker.

It is best to avoid the sun if you have acne

People who already have acne should avoid prolonged exposure to the sun. After all, if you are exposed to the sun for a long time, your skin will sweat and produce oil. If it is not cleaned in time, the oil will clog the pores, causing the acne to worsen or delay the recovery time of the acne.

Does UV light sterilization help with acne?

Ultraviolet light achieves the so-called disinfection effect by killing bacteria and other microorganisms, and unfortunately, ultraviolet light cannot kill Propionibacterium acnes which causes acne. On the contrary, UV light can thicken the stratum corneum, aggravate the blockage of hair follicles and breed Propionibacterium acnes. In addition, UV light can increase the secretion of sebaceous glands and stimulate the expansion of facial capillaries.

Ultraviolet light will directly affect the basal metabolism of cells, high temperature will reduce the specificity of cells, reduce metabolic efficiency, insufficient oxygen content in skin cells, and the accumulation of a large amount of metabolic waste. The health level of the skin will drop sharply, and not only the water and oil will be unbalanced, but also the low immunity will make the skin invaded by many bacteria. Not only will acne on the face increase over time, it will also aggravate the problem and cause great damage to the skin. Moreover, excessive ultraviolet light can cause inflammation and chronic damage to the skin (such as sunburn, sunburn, aging, etc.), and the face is inflamed. Excessive exposure to ultraviolet light can cause post-inflammatory pigmentation in the inflamed areas, making the pimples and acne marks on the face darker. Therefore, sun exposure is of no benefit to acne-prone skin. It will only aggravate acne on the face, and it is not effective in removing acne!

If you have acne-prone skin and want to use the disinfection and sterilization effect of ultraviolet light, it is better to clean the bathroom towels, sheets, pillowcases and other utensils regularly to eliminate the germs, bacteria and insects that grow on them, which will be more helpful for removing acne. At the same time, drink plenty of water, be sure to do a good job of cleaning, and moisturize in time. Moisturizing and hydrating are also necessary.
