Acne, also known as acne, is closely related to factors such as excessive sebum secretion, blockage of sebaceous glands in hair follicles, bacterial infection and inflammatory reaction. After entering adolescence, the level of androgen, especially testosterone, rises rapidly, which promotes the development of sebaceous glands and produces a lot of sebum.
At the same time, the abnormal keratinization of sebaceous gland ducts in hair follicles causes duct blockage, sebum excretion disorder and keratin plug, that is, micro-acne. Many microorganisms, especially Propionibacterium acnes, proliferate in hair follicles. Lipase produced by Propionibacterium acne decomposes sebum to produce free fatty acids, and at the same time chemotaxis inflammatory cells and mediators, eventually inducing and aggravating inflammatory reactions.
The endocrine level of acne itself is unbalanced, and coffee has a great influence on the endocrine system. Caffeine is a xanthine alkaloid compound and a stimulant of central nervous system, which can temporarily dispel drowsiness and restore energy. It is used to treat neurasthenia and coma and resuscitation in clinic. Coffee, tea, soft drinks and energy drinks containing caffeine are very popular, so caffeine is also the most widely used psychotropic drug in the world.
The high calorie of coffee accelerates the growth of acne and irritates the skin. In addition, most people who drink coffee live irregularly and often stay up late, leading to endocrine disorders, making sebaceous glands secrete too much oil, leading to pore blockage. Coupled with the influence of unreasonable diet and mental stress, acne is prone to occur.

Foods that also stimulate acne.
1, irritating food
The sudden acne on the face and body is largely caused by the human body absorbing too much irritating food. In life, irritating foods are everywhere, such as onions, ginger, garlic, peppers and so on. These are easy to stimulate the imbalance in the human body. Therefore, beauty lovers who are prone to acne should try not to eat.
2. Tobacco, alcohol and food
Tobacco and alcohol not only contain many harmful factors, long-term smoking and drinking can also easily lead to the decline of detoxification ability of human internal organs, leading to the long-term accumulation of toxins in the body, which can easily lead to skin diseases such as acne and spots.
3. High-fat food
Many people like high-fat foods such as fried dough sticks, fried buns and French fries. These high-fat foods contain extremely high calories, especially for beauty lovers who are prone to acne. This kind of food is a no-no, and it is easy to burden the human body. Because of the high oil content, it is difficult to digest and easy to form acne.
4. Foods with high sugar content
Foods with high sugar content such as ice cream, dessert and candy are many MMGG's favorites, but these foods with high sugar content are very angry, and eating too much will cause the growth of acne.
5. Fine food
Now the industry is more and more developed, and all kinds of foods are more and more refined. Many people don't like to eat coarse fiber food, but choose to use finely processed food. Although these fine foods taste good, their cleaning function and digestive ability are weak. It is recommended to eat more coarse grains to promote gastrointestinal peristalsis and detoxify!
Clinical manifestations of acne: Skin lesions are more common in the face and upper chest and back. The non-inflammatory disease of acne becomes open and closed acne. The typical lesions of closed acne (also known as baldness) are skin papules with the size of about 1 mm, and there is no obvious hair follicle opening. Open acne (also known as blackhead acne) is characterized by dome-shaped papules and obvious enlargement of hair follicle openings.
The further development of acne will evolve into various inflammatory lesions, showing inflammatory papules, pustules, nodules, cysts and so on. Inflammatory papules are red with a diameter of1~ 5 mm; Pustules are uniform in size and filled with white pus; Nodules larger than 5 mm in diameter have induration and feel pain when touched; The cyst is deeper and full of pus and blood mixture.
These lesions can also fuse to form large inflammatory plaques and sinuses. After the inflammatory lesions subside, pigmentation, persistent erythema, depression or hypertrophy scars are usually left.
