-
-
Sebaceous gland
AnatomicalStructureHolocrine secretory glands distributed across most body skin, embedded in the dermis and typically connected to a hair follicle as part of the pilosebaceous unit.
-
Sebocyte
AnatomicalStructureThe lipid-producing cells of the sebaceous gland, responsible for synthesising and secreting the components of sebum.
-
Skin
AnatomicalStructureThe body's largest organ, comprising epidermis, dermis, and subcutaneous tissue. Barrier function, structural integrity, and cellular renewal all decline through distinct but interacting mechanisms.
-
Stratum basale
AnatomicalStructureThe deepest viable epidermal layer, anchored to the dermis via the basement membrane zone, housing the keratinocyte stem cell population that feeds the entire differentiation programme above it.
-
Stratum corneum
AnatomicalStructureThe outermost layer of the epidermis, composed of 15–20 layers of anucleate corneocytes embedded in a structured lipid matrix. Functions as the primary permeability barrier.
-
Stratum granulosum
AnatomicalStructureThe stratum granulosum is the granular layer of the viable epidermis immediately beneath the stratum corneum, where keratinocytes complete terminal differentiation.
-
Stratum spinosum
AnatomicalStructureThe stratum spinosum is the epidermal layer where strong desmosomal junctions form, keratinocytes begin differentiation, and Langerhans cells survey for antigens.
-
Subcutaneous tissue
AnatomicalStructureMetabolically active deepest skin layer whose ageing drives inflammageing through adipocyte senescence. Target of cryolipolysis, cavitation, HIEMT, RF, and injection lipolysis.
