Treatment mainly lies in keeping skin clean, limiting fat diet and using drugs.
First, limit fatty foods and sweets, such as fat, cream cakes, chocolates, etc. Eat more fruits and vegetables.
Wash your face with warm water and a small amount of sulfur soap or boric acid soap every night. Remove greasy face and clean skin.
Third, it takes patience to treat with drugs according to the doctor's advice.
Fourth, it is worth noting that we should eat foods rich in vitamins, especially foods rich in vitamin A, such as pork liver, carrots and egg yolk. Correct abnormal sebum keratinization of hair follicle and prevent hair follicle blockage.
Oily skin is produced by exuberant secretion of sebaceous glands, and the characteristics of sebaceous glands in skin are determined by genetic factors. Clinically, according to the amount of fat on the skin surface, skin can be roughly divided into oily skin, dry skin, neutral skin and mixed skin.
For oily skin, sebaceous glands have a strong secretory function, and the face is greasy, which is not easy to clean and shiny, which affects the appearance; At the same time, it is also prone to facial skin diseases, such as acne. Seborrheic dermatitis and so on.
Controlling the excessive secretion of sebaceous glands and relieving the symptoms of oily skin are the key to maintaining skin health.
The normal development and maintenance of sebaceous glands is necessary for the dynamic balance of skin. When sebaceous glands atrophy and the lipid components of sebum are destroyed, it will bring certain skin dysfunction.
The factors affecting the secretory function of sebaceous glands include: sex and age, endocrine factors, skin humidity, diet and nutrition.
1. Gender and age
The secretory function of sebaceous glands is very strong at birth, and it drops to a very low level after 6 months, and it is still very low in childhood.
Since puberty, the secretion of sebaceous glands in men and women has gradually increased, reaching the peak at the age of 16 ~ 20, and maintaining this level in the future.
After the age of 40 for women and 50 for men, the secretion of sebaceous glands began to decrease.
2. Endocrine factors
Sebaceous gland is the target organ of androgen, and its hyperfunction is mainly related to the imbalance of sex hormone secretion.
Testosterone increases the volume and secretion of sebaceous glands. Especially, the activity of 5α- reductase, the catalyst of sebum synthesis in human body, is too high, which leads to the increase of dihydrotestosterone secretion, which leads to the increase of sebaceous gland secretion.
3. Skin humidity
The humidity on the skin surface will affect the secretion and diffusion of sebum. When the skin surface humidity is high, the emulsification and diffusion of sebum will become slow. When the skin is in a dry environment for a long time, sebaceous glands will be overactive and produce abnormal oil.
4. Dietary factors
Dietary factors will affect the secretion of sebaceous glands. Eating greasy food, spicy food and high-sugar and high-calorie food will increase the secretion of sebaceous glands.
