Most acne is caused by two reasons. One is that the skin belongs to oily skin, sebaceous glands are too developed, and sebum secretion is too strong. If the pores are blocked or the oil discharge is not smooth due to other reasons, the sebaceous glands will continue to secrete, and sebum will accumulate and protrude in the pores and become acne.

Another reason is the imbalance of hormone secretion in the body, which makes the skin acne. This reason is more common in adolescence. The imbalance of hormone secretion will indirectly lead to excessive sebum secretion, thus further aggravating the situation of acne.

The acne can be treated by laser, which can penetrate into the deep skin where Propionibacterium acnes is located, and the photothermal energy is aimed at Propionibacterium acnes, which takes effect quickly, stimulates the proliferation of endogenous lymph, and quickly kills Propionibacterium acnes in the skin, so that normal skin tissues are not damaged and no scars are left.
