Cause of disease caused more acne, pathogenesis, but also more complex, mainly with the following factors:
1), androgen excess, leading to increased rate of sebum secretion;
2), regulation of sebum secretion out of control;
3), hair follicles, sebaceous glands and sebaceous gland hyperplasia hyperkeratosis.
Blocked by the mouth of the formation of hair follicle sebaceous glands of acne, can develop into inflammatory papules, pustules, nodules, cysts, pink tumor, cyst, the formation of pigmentation and India, large pores, and even scars and other skin damage.
Whitehead acne: skin cells in hair follicles are blocked sebaceous gland mouth, keratosis, skin and fat filled them with the outside world is not the same, the formation of closed acne, bald look for the slightly protruding.
Blackhead: hair follicles and sebaceous glands within the sebum plug by keratosis, and opening and the outside world, the formation of open acne, the surface appears to be large or small, black spots.
Pimples: Acne is the most fundamental damage. Sebaceous glands in the hair follicle population congestion, the formation of hypoxic environment within the sebaceous hair follicles, anaerobic Propionibacterium acnes multiply, break down sebum, producing chemokines, leukocyte accumulation and inflammation of pimples, so this kind of pimples are inflammatory damage.
