Closed facial acne, also known as whiteheads and acne, can usually be eliminated by improving lifestyle habits, applying medications and using medical aesthetics, and sometimes a combination of methods is needed. However, the elimination effect usually depends on the severity of the acne, so you should choose the appropriate treatment according to your situation or under the guidance of your doctor. First of all, if the number of closed pimples is small, it is more common in life and usually does not require special treatment. It can usually disappear on its own by improving lifestyle habits, such as eating a light diet, reducing or avoiding high-fat, high-sugar and spicy stimulating foods, regular rest and rest, appropriate exercise, and avoiding late nights. Secondly, if the number of acne is large or if it affects the aesthetic appearance, topical application of retinoic acid drugs such as retinoic acid ointment and fruit acids can be applied under the guidance of a doctor. Topical adapalene gel may also be used if the closed acne is small and occurs in scattered areas. When the patient’s skin is sensitive, a moisturizer for allergy and oil control can be used and topical medication can be applied after the skin condition has improved. Finally, peeling treatment with salicylic acid and fruit acids can be used in hospitals or regular medical institutions to improve the skin condition and reduce the appearance of acne. For acne that has already appeared, acne can be cleared in a regular medical institution, mainly by negative pressure attraction, which is a damaging operation and should not be cleared too much each time to prevent damage to the skin barrier.
