What happens to skin during the aging process?

As skin ages, it undergoes several physiological changes that significantly affect its appearance and texture. One of the key aspects of the aging process is the loss of elasticity and moisture. This occurs because the production of collagen and elastin, proteins responsible for maintaining skin's firmness and elasticity, decreases over time. Additionally, the skin's ability to retain moisture diminishes due to a reduction in natural oils, leading to a drier and less plump appearance.

The loss of elasticity can result in sagging and the formation of wrinkles, as the skin becomes less capable of springing back into place after stretching. The decrease in moisture not only contributes to dryness but can also lead to a rough texture and a dull complexion. Therefore, the correct answer highlights the significant impact of aging on skin, specifically regarding its loss of both elasticity and moisture.
