Differential Effects of Photoaging vs Intrinsic Aging on the Vascularization of Human Skin

Abstract

In Korean skin, chronic photodamage results in a gradual decrease in the number and size of dermal vessels over several decades of sun exposure, most likely due to degenerative changes of the dermal extracellular matrix. Because the present investigation was restricted to ethnic Korean volunteers, future studies are needed to evaluate whether similar changes can be observed in whites.
