Before & After GalleryDepigmentation
Depigmentation refers to loss of skin color due to a reduction or absence of melanin, the pigment produced by melanocytes. Melanin is responsible for skin, hair, and eye color, and it also plays an important role in protecting the skin from ultraviolet (UV) damage. When melanin production is disrupted or melanocytes are damaged or destroyed, lighter areas of skin may appear.
It is important to distinguish depigmentation from hypopigmentation. Hypopigmentation describes partial lightening of the skin, where some melanin remains. Depigmentation, by contrast, implies complete or near-complete loss of pigment in the affected area, resulting in very light or white patches.
One common cause of pigment loss is post-inflammatory depigmentation, which can occur after skin injury or inflammation such as eczema, burns, aggressive cosmetic procedures, or infection. In these cases, melanocytes are temporarily or permanently impaired. Post-inflammatory depigmentation may improve over time, but recovery can be slow and is not always complete.
Vitiligo is a distinct medical condition characterized by depigmentation due to autoimmune destruction of melanocytes. It often presents as sharply defined white patches and may progress over time. Vitiligo is not contagious and can affect all skin types, though it is often more noticeable in darker skin tones.
Accurate diagnosis is essential, as management and prognosis vary depending on the underlying cause of pigment loss.
Individual results may vary.
