Explanation:
Detailed explanation-1: -Levels of elastin, collagen, and hyaluronic acid gradually decrease in aging, sun-protected skin, thereby contributing to a loss of structural integrity and elasticity.
Detailed explanation-2: -In skin ageing, there is a reduction in the number of fibroblasts that synthesize collagen and vessels that supply the skin which leads to an increase in laxity and hence forms wrinkles [4] (Fig. 1). The sun-exposed skin gradually leads to sagging of skin.
