Hormones that affect the skin
During most people’s menstrual cycles, the skin experiences different times of dryness and oiliness. The skin can become the most problematic during your period and a couple of days prior to it. This is when you can expect period-related pimples and acne. All this results from the buildup of sebum underneath the surface, causing the appearance of oily skin.
If you’ve ever wondered what hormone causes oily skin, the answer actually involves the effects of multiple hormones. Imbalances in certain hormones — like progesterone, estrogen, and testosterone — affect your body’s natural oiliness and the appearance of dry skin.
Estrogen reaches a high point and a low point during the menstrual cycle. It causes changes in the skin by influencing its texture and thickness, as well as structural integrity and fluid balance. Changes in hormonal levels can cause acne, and progesterone plays a big role in this process. Progesterone causes breakouts by closing skin pores and inducing sebum buildup underneath the surface of the skin.
