When it comes to skin condition, the decline in oestrogen and collagen plays a significant role. Oestrogen stimulates the production of collagen, an essential protein for healthy, firm skin (as well as for muscles, joints, and bones, which also rely on collagen to function properly).
Collagen keeps tissues throughout the body strong and resilient. When oestrogen levels drop, collagen in the skin also decreases. The result? The skin becomes thinner, wrinkles form, and external factors affect the skin more easily. Collagen also helps the skin retain water, so less collagen means less hydrated skin.
Additionally, oestrogen helps regulate the enzymes that break down collagen. When there is less oestrogen in the body, these enzymes can become more active, causing collagen in the skin to break down more quickly.
Moreover, the sebaceous glands (which keep the skin supple and protect it from drying out) produce less oil as you age. While men experience minimal decline, oil production in women gradually decreases after menopause, making the skin drier and prone to itching.
