”Acne”, “acne” and “pimples” are all common names for acne, a chronic skin disease that is more common in young men and women. Acne occurs mainly due to the increase in androgens during development, which leads to an increase in sebaceous gland activity and stimulates increased secretion of sebaceous glands. At the same time, the walls of the sebaceous gland follicles become keratinized and block the pores causing poor sebum discharge, thus causing inflammation of the hair follicle sebaceous glands, mainly related to Propionibacterium acnes infection. If acne is not treated in a timely manner, it seriously affects the aesthetics of the appearance. Moreover, the impact on the appearance is not only limited to the onset of the disease, but may also cause lifelong regret due to the scars left behind, which can have a great impact on the physical and mental health of the patient. In addition to the active treatment of acne patients, it is also very important to master the correct care methods to prevent recurrence of the disease. 1, acne patients’ skin generally belongs to oily skin, take the morning and before bedtime alternately use neutral alkaline soap and facial wash only suitable for oily skin, and gently massage with the fingers of both hands in the direction of the skin line for 3-5 minutes to enhance the decontamination power of soap and facial wash, and then wash with warm water to thoroughly remove the dust and grease on the skin that day. If there is more facial dust and grease, you should rinse with warm water in time. The general number of times to wash your face 2-3 times a day is appropriate. Do not use cold water to wash your face, to prevent pores from clogging and acne aggravation. 2, avoid using oily or powder cosmetics, use water quality care products as appropriate, especially avoid heavy makeup. Before going to bed, you should thoroughly remove the cosmetics of the day, and avoid applying nutritional creams before going to bed, so that the skin at night is relaxed, unobstructed and fully breathes. 3, avoid using your hands to touch the acne or use your hair and foundation cream to cover the rash, especially to overcome the bad habit of squeezing and pressing the acne with your hands, because the bacteria on your hands and the spoils on your hair can easily infect your skin and aggravate the acne, while squeezing and pressing can cause permanent depression scars, leaving a lifelong regret. 4, pay attention to not often be direct sunlight, because this will make the sweat and sebaceous glands secretion active, blocking pores, accelerating the inflammation of acne. Therefore, in the hot summer, both men and women should be well protected from the sun. 5, diet should pay attention to “four less a more a taboo”, that is, eat less spicy food (such as chili, onion, garlic, etc.), eat less greasy food (such as animal oil, vegetable oil, etc.), eat less sweets (such as sugar, coffee), eat less “hair” (such as dogs, mutton, etc.) Eat more fresh vegetables and fruits, and refrain from smoking and alcohol. 6, adequate sleep, moderate exercise, work and rest, and a happy spirit are very beneficial to the treatment of acne care. Once you have acne, do not be burdened psychologically, try to maintain a light heart, avoid anxiety and irritation, so as not to cause neuroendocrine disorders, making acne aggravated.
