According to statistics, 80% to 90% of adolescents in China have been troubled by acne, especially in hot summer days when acne develops more often. Acne, commonly known as acne and pimples, is a common chronic inflammatory disease of the sebaceous glands of hair follicles. It is the most common skin disease in dermatology and is also a serious cosmetic problem for patients. Although acne is relatively common, there are certain misconceptions about acne that many people have. According to dermatologists, acne patients are often in a hurry to get treatment and there are five major misconceptions. He reminded that the treatment of acne needs to clarify the cause and treat the symptoms, do not hearsay, use some so-called fast-treatment creams, a little carelessness, may aggravate the condition to affect the complete treatment. Myth 1: Sun exposure can cure acne Correct: Sun exposure is restricted to acne-prone areas. People find that their skin peels off after sun exposure and acne looks better in the short term, does this mean that sun exposure can cure acne? Experts suggest that the appearance of improvement is more due to the fact that sun exposure can redden the skin and cover up acne-induced erythema. The clinical opinion is that sun exposure may irritate the skin, especially long-term sun exposure, and will only aggravate acne. Therefore, acne-prone areas should be limited to sun exposure. Myth #2: Stress causes acne Correct: Only certain psychiatric drugs will Experts analyze that the reason why stress is rumored to cause acne is because excessive mental stress will affect the body’s endocrine system, “This is just a theory”. Stress itself does not cause acne, but rather certain psychiatric medications do. Instead of worrying about stress causing acne, you should spend more time researching how to treat acne. Myth #3: Masturbation causes acne Correct: Androgens are the real culprit. Masturbation causes acne,” a misconception that originated in the 17th century to discourage young people from masturbating, has little scientific basis in fact. Experts say that the onset of acne is related to androgen levels. What is the relationship between acne, androgens, and sexual behavior? First, high androgens may increase the drive for sexual behavior; second, high levels of androgens can cause acne; third, increased sexual behavior and acne occur as a result of high androgen levels, rather than sexual behavior itself aggravating acne. Myth 4: Washing more often can clear acne Correct: You can only wash twice a day Experts point out that, contrary to commercial propaganda, dirt does not cause facial discoloration and pores are not clogged by surface dirt, so washing more often cannot clear acne. The occurrence of acne is closely related to factors such as excessive sebum production, blockage of hair follicle sebaceous ducts, bacterial infection and inflammatory reactions. Generally speaking, it is the blockage of the hair follicle wall deep in the skin that is the cause of acne. Therefore, excessive washing of the face will not only fail to prevent acne from occurring, but will instead lead to blockage of the hair follicle opening; scrubbing with a towel can also lead to pore inflammation. To prevent and care for acne, the best way to wash your face is to wash it gently with both hands and only twice a day.
