1. Skin belongs to oily skin, sebaceous glands are too developed and sebum secretion is too exuberant. If the pores are blocked or the oil discharge is not smooth due to other reasons, sebaceous glands will continue to secrete, and sebum will accumulate and protrude in the pores and become something similar to acne.

2. The imbalance of hormone secretion in the body makes the skin grow acne-like. The imbalance of hormone secretion will indirectly cause excessive sebum secretion, which will further aggravate the condition of acne. Usually pay attention to breast hygiene, often clean, change bras and underwear frequently, and don't squeeze them to avoid infection.
