Vaginal aging occurs due to a combination of hormonal changes, physical stress, and natural tissue remodeling over time. Declining estrogen levels can lead to thinning, dryness, and reduced elasticity, while pregnancy and childbirth may stretch and weaken vaginal and pelvic floor tissues. Aging related loss of collagen and elastin further contributes to decreased firmness and tone, and repetitive friction or trauma can add to discomfort or laxity. Lifestyle factors and genetics also influence tissue resilience, shaping how and when these changes become noticeable.
