Epidermal Pigmentation

  • Melanocytes – melanin producing cells – stimulated by UV (sunlight)
  • Over-excited Melanocytes produce excess melanin to create solar lentigineson the skin surface
  • The light emitted targets the particles of excess melanin – heating them rapidly
  • Fragment into smaller particles
    – Come to surface
    – Removed by the body’s natural processes (Lymphatic)
