Summary of characteristics of normal skin using OCT

LOCATION	FEATURE	QUALITIES IN NORMAL SKIN
Epidermis	Surface shape	Bumpy, textured
	Thickness	Typically 80–110 µm depending on location, age, and other factors
	DEJ shape	Undulating (flattened in elderly)
	Stratum corneum	Appears as white line (except palms/soles)
	Brightness	Darker than dermis
Vasculature	Vessels	Uniform in size and shape, horizontal, do not meet the DEJ, Plexus depth 250µm
Dermis	Texture	Even textured
	Brightness	Uniform, lighter than epidermis
	Adnexal structures	Hair follicles and glands present

DEJ: dermal-epidermal junction; OCT: optical coherence tomography
