Dermal atrophy, decrease in subdermal adipose tissue, loss of elastic fibers and laxity of skin Decrease on langerhans cells, decrease in melanocyte function Decrease in rete pegs and dermal papillae resulting in flattened dermal-epidermal jx allowing easier separation with trauma Decrease in fibrocytes resulting in decrease collagen content and synthesis. Decrease in elastic fibers in papillary dermis resulting in skin laxity. Atrophy of upper and lower lips

Three layers Epidermis Dermis papillary: loose collagen, blood vessels, fibrocytes reticular: compact collagen, fewer fibrocytes Dermis is a mixture of collagen made by fibrocytes, reticulin, elastic fibers embedded in matrix of glycoproteins and glycosaminoglycans aka “ground substance” Superficial fascia
