Vitiligo

Vitiligo

Vitiligo is a skin disorder that is acquired and idiopathic, meaning its cause is unknown. It is characterized by the selective loss of melanocytes, which results in hypomelanosis or a decrease in melanin production. This leads to patches of skin that have little to no pigment, causing a noticeable contrast with the surrounding skin.From: Surface Imaging for Biomedical Applications [2019], Formulation and characteristic evaluation of tacrolimus cubosomal gel for vitiligo [2022]

Vitiligo is a skin disorder that makes the skin areas paler in contrast to normal skin or completely white due to the lack of pigment melanin. Pigment melanin is a colour pigment found in skin, eyes and hair. It is produced by melanocytes through processes called melanogenesis.

Vitiligo is an acquired idiopathic dermatological disorder characterized by the selective loss of melanocytes, that is, hypomelanosis.[1,2] About 85–95% of the symmetrical lesion’s cases represent non-segmental vitiligo whereas unilateral lesions commonly appear in segmental vitiligo. Younger people more prone to get segmental vitiligo when compared to non-segmental vitiligo.[3] Etiology of vitiligo is unknown, it may be due to lack of immunity power and reduction of melanocyte count in the skin , family history (heredity) or externals factors such as sunburn, stress or exposure to industrial hazards,[4] which results in the smooth, non-scaly, chalky-white macules found in several tissues in the skin, hair follicles, eyes, and inner ear.[5] The prevalence rate of vitiligo is about 0.5–1% of the world population.
