Medical tattooing for Vitiligo
These stains can often psychologically be disturbing. They can, but not always, be camouflaged or covered by permanent make up or medical tattooing.
Vitiligo in the face, a skin disorder, has no pigment cells in the skin produce pigment (melanin) anymore. This appears in (small) white spots on the skin surface. It will probably be a minor derailment of the immune system so the body creates antibodies against its own pigment cells.
The result is non-aesthetic discolored spots on the skin of vitiligo.
