Superficial Dermis
The uppermost layer of the dermis, immediately below the epidermis, which is the target plane for intradermal injection techniques in aesthetic medicine.
Full Definition
The superficial dermis (also termed the papillary dermis) lies directly beneath the epidermis and is characterised by fine collagen fibrils, abundant capillary loops, and sensory nerve endings. In aesthetic practice, this plane is targeted by superficial microneedling, intradermal mesotherapy microinjections, and some superficial chemical peel actions. Editors should not conflate 'superficial dermis' with 'epidermis' (the most superficial skin layer) or 'deep dermis' (the reticular layer), as the distinctions have clinical significance. Correct usage requires the adjective 'superficial' to precede 'dermis,' not 'dermal.'
Usage
Usage note: Synonymous with 'papillary dermis' in histological usage. Confirm which term the author or journal prefers and apply consistently.
