Melanocytes increase melanin production when they detect stress: ultraviolet radiation, inflammation, hormonal shifts, or repeated irritation. Over time, signaling pathways (including tyrosinase activation and inflammatory mediators) stimulate excess pigment synthesis. When melanin is produced faster than it can be evenly distributed and shed through normal epidermal turnover, it accumulates in c
