Sebum production

Sebum production is the result of lipid synthesis and secretion by sebaceous gland cells (sebocytes), occurring predominantly in the dermis and strongly regulated by hormones, notably androgens (testosterone, dihydrotestosterone)[1][5][6][7]. Sebum is an oily substance consisting of triglycerides, fatty acids, wax esters, and unique lipids like squalene and sapienic acid, serving to lubricate, moisturize, and protect the skin and hair[2][3][7]. The production process involves stem cell proliferation, sebocyte differentiation, active lipid synthesis, and cell death via holocrine secretion[3][5]. Sebum also supports antimicrobial defense via lipid composition and the production of antimicrobial peptides[4]. Its dysregulation plays a central role in skin disorders such as acne and seborrheic dermatitis, and interventions typically target the underlying cell types, enzymes (such as 5-alpha-reductase), or receptors (such as androgen receptor)—not “sebum production” as a direct molecular target[1][4][5].
