What causes acne on the back of the face?

Acne refers to acne. Acne on the face and back is mainly caused by hormone level changes, excessive sebum secretion, bacterial infection and other reasons.

1, hormone level changes

When the body androgen level increases, it will promote sebaceous glands to secrete more sebum, resulting in excessive oil secretion, easy to block pores, and then cause acne. For example, in adolescence, due to the body development, hormone levels are unstable, acne is prone to occur.

2, sebum secretion

If sebaceous glands are too active, a lot of sebum is produced, and these sebum cannot be discharged in time, it will accumulate in hair follicles, creating conditions for bacterial breeding, thus causing acne. Bad living habits, such as long-term high sugar, high fat diet, may stimulate sebum secretion.

3, bacterial infection

is mainly Propionibacterium acnes, which is easy to reproduce in an oil-rich environment, and its metabolites will induce inflammatory reactions, leading to acne redness and pain.

If acne is serious, patients can go to the dermatology department of the hospital in time for treatment.
