商品簡介
Melanin governs the color of human skin, hair, and eyes. Disruption of its synthesis, transport, or melanocyte survival leads to disorders ranging from melasma and post-inflammatory hyperpigmentation to vitiligo and albinism. Causes include ultraviolet damage, hormonal changes, drugs, metabolic deficits, genetic mutations, and autoimmune attacks. Beyond cosmetic concern, dyschromia correlates with photo-oncogenic risk, impaired barrier function, and substantial psychosocial morbidity. The chapters will explore pathophysiology, advanced, cutting-edge diagnostics, and evidence-based therapeutic interventions, equipping clinicians with targeted, patient-centered strategies and new research topics. This book foreshadows a paradigm shift from pigment camouflage to molecular restoration.
