identify what affects the thickness of the skin
About 90% of the skin's thickness is from the dermal layer of the skin, and much of the variation in skin thickness there is due to variations in collagen and elastin levels.ollagen and elastin break down with age. A gradual decrease in subcutaneous fat in the hypodermal layer of the skin also occurs with age, further decreasing skin thickness. Variations in thickness of these layers have the most dramatic effect on skin appearance.
