Answer 1

Skin wrinkles and sagging are caused by a combination of factors, including UV radiation, aging, and hormonal changes.

Step-by-step explanation:

Skin wrinkles and sagging are caused by a combination of factors, including UV radiation, aging, and hormonal changes. UV radiation can damage collagen fibers in the skin, leading to an acceleration of the aging process and the formation of wrinkles. Aging itself leads to a thinning and sagging of the skin due to reduced cell division, metabolic activity, and collagen production. Hormonal changes, such as a decrease in estrogen during menopause, can also contribute to skin aging and sagging.
