How do hormone changes in girls influence acne development?

Hormone changes in girls, particularly during puberty, trigger an increase in androgens, which are male hormones present in both sexes. These hormones stimulate the sebaceous glands in the skin to produce more sebum, an oily substance that can clog pores. When combined with excess dead skin cells and bacteria, this can lead to the development of acne. Additionally, hormonal fluctuations during menstrual cycles can exacerbate acne severity in some girls.
