Over a woman's lifetime, _________.

• A. Hormonal changes will change her skin in various ways throughout her life
• B. Environmental factors can affect skin
• C. Diet influences skin more than hormones
• D. Sleep affects skin less than hydration

Answer: (A)

Hormones act as master regulators of skin physiology, shaping how the skin behaves across different life stages. Changes in estrogen, progesterone, and androgens modulate oil production, collagen synthesis, hydration, and barrier function. For example, puberty brings increased androgens that boost sebum and can lead to acne; pregnancy alters oiliness, pigmentation, and elasticity; menopause lowers estrogen, often causing dry, thinner skin with less collagen. Across a woman’s life these hormonal shifts occur repeatedly and influence a wide range of skin traits, producing diverse changes over time.

Environmental factors, diet, sleep, and hydration certainly affect the skin, but they do not produce the same patterns of change driven by the endocrine fluctuations that occur through puberty, pregnancy, and menopause. That broader, ongoing influence of hormonal changes makes the statement the best fit.
