Detailed answer

Hormone replacement therapy (HRT), specifically estrogen-based therapy, can increase oil production in the skin, leading to clogged pores. This is because estrogen promotes the growth of sebaceous glands, which are responsible for producing oil. The increased oil production can mix with dead skin cells and other impurities, leading to the formation of clogged pores. Additionally, HRT can also increase testosterone levels, which can further contribute to clogged pores and acne breakouts. It is important to note that not everyone who undergoes HRT will experience worsened clogged pores, as individual responses may vary. Proper skincare routines, such as regular cleansing and exfoliation, can help manage and prevent clogged pores during hormone replacement therapy.
