Ever notice discolored patches on your skin? It could be dyschromia.
Dyschromia is a condition characterized by changes in the color of the skin, hair, or nails. Skin color is determined by the number and activity of melanocytes — the cells responsible for producing pigment. When this process is disrupted, it can result in areas of lighter or darker skin.
- Hypopigmentation refers to lighter patches.
- Hyperpigmentation refers to darker patches.
Common examples includemelasma, which causes dark patches, andvitiligo, which leads to lighter, depigmented areas.Physical symptoms usually do not accompany dyschromia, though some individuals may experience mild itching in the affected areas.
