Is it true that Vitiligo causes realistic loss of skin pigmentation?
Yes. Vitiligo is an autoimmune skin condition characterized by the progressive loss or destruction of melanocytes, resulting in characteristic patches of depigmentation.
Verdict: SUPPORTED · 12 sources for, 0 against · Last checked
The analysis
The retrieved papers overwhelmingly confirm that vitiligo involves the destruction or loss of melanocytes, leading to skin depigmentation and white patches. All relevant papers support this mechanism.
Evidence for · 12
Indicates that vitiligo involves IFN-gamma-induced melanocyte destruction and depigmentation.
