People with oily skin have a high secretion function of sebaceous glands and are prone to some corresponding skin diseases, such as acne vulgaris, seborrheic dermatitis, and seborrheic alopecia. The main reason for this condition is the increased secretion of androgens, but there are also some other factors, such as diet and nutrition, emotions, seasons, etc. General treatment measures are to maintain a regular life, get enough sleep, eat more vegetables, limit fat and sugar diet, avoid alcohol and spicy stimulating food, and avoid excessive mental tension; targeted treatment can go to the dermatology department for systematic treatment, but whether it is oral medication or topical medication or seborrhea. Oral medications or topical medications or cosmetics are not able to completely restrict sebum secretion, and often require several weeks of continuous use before the effect can appear. Personal care measures: apply warm water to wash your face, warm water is good for sebum removal, choose alkaline soap, etc.; you can see a Chinese doctor, the effect is still good.
