Acne, commonly known as “pimples,” is a very common skin disease with an incidence rate of 45.6%. The peak incidence of acne is between 16 and 19 years old for men and 14 to 16 years old for women, and can last until 30 to 40 years old. The cause is closely related to the level of androgens in the body, sebaceous glands and microorganisms in the hair follicles. In mild cases, it affects the aesthetics, and in severe cases, it leads to the destruction of facial skin and leaves irreversible scarring. Acne is a skin disease that is prone to recurrence and treatment requires patience and confidence. The goal of acne treatment is to reduce symptoms on the one hand and to avoid recurrence on the other. First of all, the concept of systemic treatment should be established: it is an inflammatory disease caused by the action of multiple factors, so systemic treatment is necessary to achieve good results. For the cause of the disease, we should reasonably choose oral medication, reasonably choose topical medication for the treatment of lesions, cooperate with acne squeezing, inversion, laser and photodynamic treatment, choose appropriate medical skin care products, and adhere to a sufficient course of treatment. 1.Oral medication: including the use of anti-androgenic drugs to inhibit sebum secretion and anti-acne propionibacterium; 2.Topical medication: including the use of retinoic acid cream, acne cryptone gel, benzoyl peroxide gel and antibiotic ointment; 3.Physical therapy: for inflammatory papules, acne and pustular pimples can be squeezed and then treated with a special herbal mask or red and blue light; for sebaceous glands that secrete excessively and For sebaceous glands and propionibacterium acnes that reproduce too quickly, aminoglutaric acid-photodynamic therapy can be used; for the depressed worm-like scar left after acne, pulsed intense light therapy (IPL) or fractional (pixel) laser treatment can be used. 4, the choice of medical skin care products: medical skin care products can play a supplementary therapeutic role, helping to control oil secretion, anti-inflammatory, soothing, regulating the balance of sebum and moisture, helping the skin to rebuild and repair the sebaceous film. The common medical skincare brands on the market today are Winona, Skin Spring, Avène and so on. However, the choice of skin care products needs to be made under the guidance of a professional doctor. 5. Adhere to a sufficient course of treatment: Acne treatment often requires maintenance and consolidation, and usually the treatment takes 3 to 6 months. You should not be in a hurry, but have patience and confidence. 6, Other aspects: Avoid sun exposure, radiation (less exposure to computers and TV), avoid eating foods that are too sweet, too oily and too spicy, and avoid stimulation by tobacco and alcohol; use cosmetics reasonably.
