During the second phase, women’s testosterone becomes more prominent, causing sebaceous glands to secrete thicker sebum, causing oily skin (and adult acne in some women). It also causes the development of facial hair in some women, particularly on the chin.
As estrogen levels drop, fat is redistributed throughout the body and underneath the skin, resulting in a loss of the supportive fat that holds the body’s shape and maintains the skin’s firmness. Thus, the skin and various body parts begin to sag.
