KK: /dɪˌpɪɡ.mənˈteɪ.ʃən/
The process of losing or removing the natural color from the skin, hair, or other tissues.
The patient experienced depigmentation on their arms after the treatment.
Depigmentation → It is formed from "de-" (meaning removal or reversal) and "pigmentum" (from Latin, meaning pigment or coloring). The word "depigmentation" refers to the removal or loss of pigment, resulting in lighter skin or hair color.
Think of 'removal' ('de-') of 'color' ('pigmentum') — that's why depigmentation means losing color.
