Suntanned skin is not necessarily healthy.

Core Tip: In recent years, wheat-colored skin, which symbolizes health, is more popular than fair skin. Many people do not hesitate to use makeup or sun exposure to create wheat-colored skin. But now some Japanese experts point out that "tanned skin is not necessarily healthy". Ms Suzuki, a Japanese dermatologist, pointed out that people have many misunderstandings about sunbathing. Incorrect sunbathing will only sunburn the skin and lead to various diseases. She pointed out that sunlight does have bactericidal effect, because ultraviolet rays can destroy cells. However, ultraviolet rays can also kill fungi that protect the skin surface, thus destroying the protective layer of the human body, leading to decreased immunity and susceptibility to diseases such as colds.
