Acne vulgaris is a chronic inflammation of the hair follicles and sebaceous glands. 80% of patients are between the ages of 14 and 25, so it is also known as “pimples”. Acne symptoms can be mild or severe, and while light acne can be considered a feature of adolescent skin, heavy acne tends to make the patient’s spirit more depressed, seriously affecting daily life and social activities. So how to treat acne? 1, sebaceous glands overproduction Sebaceous glands keep producing sebum, which reaches the epidermis through the discharge ducts and hair follicles. Since testosterone in men has the effect of promoting sebum synthesis and secretion, sebaceous glands will proliferate and hypertrophy rapidly during the period of development of male secondary sexual characteristics, especially in the face, back, chest and other parts of the body. The increase of luteinizing hormone in the period after the monthly ovulation will also stimulate the sebaceous hypertrophy and hyperplasia, which will lead to an increase in sebum secretion, and the excess sebum can not be discharged in time, and stagnate in the hair follicles, which will lead to the occurrence of pimples. In men after puberty, women before the menstrual cycle, the phenomenon of increased acne. 2.Hair follicle epithelial hyperkeratosis The exfoliation of the hypertrophied stratum corneum within the hair follicle will also block the hair follicle, resulting in the opening of the hair follicle and sebaceous glands become narrower, and normal sebum discharge is blocked, and sebum stagnation in the hair follicle, which will lead to the emergence of pimples. Performance in the skin is not clean, the stratum corneum is too thick to block the pores and induce acne, or the stratum corneum in the physical stimulation, such as ultraviolet radiation, its keratinization speed will increase, become hypertrophic, so, strong sunbathing will also appear after the phenomenon of increased acne. 3, the influence of bacteria Once the sebum stagnation in the hair follicles due to the reasons mentioned above, the skin in the follicles often in the Yin, such as acne bacillus, staphylococcus and so on will reproduce. The lipolytic enzyme of the bacteria will break down triglycerides, the main component of sebum, into free fatty acids. These low-grade fatty acids stimulate the epithelium of the hair follicle and damage the wall of the follicle, causing an inflammatory reaction in the connective tissue around the follicle, and even pus. In addition to the above causes, acne is also related to external malignant stimuli such as fatigue and mental overstress, as well as genetic factors and food influences. Considering the above reasons for the formation of acne, it is especially necessary to take the following skin care methods for the prevention and treatment of acne. Prevention and treatment of acne 1, often keep the skin clean, to promote the dissolution of keratin peeling, to avoid blocking pores. 2, general oily skin and light acne: summer can be used with good sebum inhibition of skin care products, weakening the skin often in the bacterial reproduction and decomposition capacity. 3, more serious acne, should be used regularly containing anti-inflammatory antiseptic and sebum inhibitor containing skin care products for skin care. 4, avoid excessive fatigue or often in a state of tension. When the human body is too tired or in a state of chronic mental tension, it is easy to make the balance of the endocrine system is affected, psychological and physiological changes will occur, as well as lead to the emergence of problematic skin. So in addition to maintaining adequate sleep in daily life, but also to maintain a happy mood. 5, pay attention to diet regulation. Do not or try to eat high fat, too sweet, or stimulating food, such as chocolate, sugar, fat meat, coconut, coffee and so on. After a variety of skin care methods and self-regulation, I believe that acne will soon disappear from your face until cured!
