The basis of acne is oily skin, where the sebaceous glands produce too much and the follicular sebaceous ducts become blocked and secondary infections occur. There is a classic saying: No oil, no acne. The principle of acne treatment is anti-inflammation and unblocking of pores. Commonly used medications, including oral Tylenol and topical retinoids, work by inhibiting oil secretion and unblocking pores, and have good therapeutic effects. But at the same time, it also inevitably brings side effects: dry skin peeling, many patients can not tolerate, or even have to give up the medication. In addition, some topical drugs, such as benzoyl peroxide, zinc sulfate lotion and so on, have a good anti-inflammatory effect, but the skin irritation reaction is obvious, appearing red spots, stinging and other symptoms, also many patients can not tolerate. Therefore, many patients cannot adhere to the treatment, resulting in treatment failure. I have been engaged in clinical experience for many years, the solution to this problem is moisturizing skin care, improving the condition of the skin and enhancing tolerance to drugs, so that patients can cooperate with doctors to adhere to treatment, while also achieving the effect of improving skin quality.
