the production of sebum , which aids in moisturizing skin and fortifying the skin barrier .
Estrogen insufficiency results in a reduction in epidermal and dermal thickness . Thin skin becomes more vulnerable to free radical damage , oxidative stress , and other stressors . Additionally , lower estrogen levels lead to decreased collagen production . Consequently , skin will thin and wrinkle . Females face a natural decline in estrogen in their mid-to-late 30s . Sleep impairment worsens the shortage .
Skin can be affected if testosterone is either too high or too low . A correct balance is essential for both men and women . Older males face decreasing levels as age increases – this situation is exacerbated by poor-quality sleep . When testosterone decreases , skin loses elasticity , dermal thickness , and density .
The hormone progesterone supports skin elasticity and circulation . Levels naturally begin to decline in women in their mid-to-late 30s . Progesterone levels also decline with sleep deprivation , and “ glowing skin ” all but disappears .
