Why Does Acne Worsen Before Menstrual Cycles
Many women notice their skin breaking out right before their period starts. This happens because of changes in hormones during the menstrual cycle. Hormones like estrogen and progesterone shift levels each month, and these shifts can trigger more acne.[1][2]
In the second half of the menstrual cycle, after ovulation, progesterone rises. This hormone boosts oil production in the skin. The skin has glands called sebaceous glands that make sebum, an oily substance. When sebum increases, it mixes with dead skin cells and can clog pores.[1][3]
Androgens, which are male-like hormones present in women too, also play a big role. These hormones go up before the period and make the sebaceous glands work harder. More oil means more blockages, which lead to pimples, blackheads, and whiteheads.[2][3]
This type of acne often shows up on the jawline, chin, and lower face. It is called hormonal acne because it ties directly to the cycle. Stress can make it worse by adding to hormone changes.[4]
The breakouts usually peak a few days before bleeding starts and ease up after the period begins. Not every woman gets this, but it is common in teens and adults.[1][5]
Keeping skin clean, using gentle products, and managing stress can help. Some women find relief with birth control pills that balance hormones, but talk to a doctor first.[2][3]
