• Inflammation and post-inflammatory hyperpigmentation (PIH): Acne, insect bites, eczema or even aggressive exfoliation can provoke inflammation. The skin may respond by producing excess pigment, which can persist long after the initial issue has healed.

• Hormonal influences: Pregnancy, contraceptives and hormone fluctuations can trigger mel
