Recognizing melasma Melasma can be epidermal, dermal or mixed However, Wood’s light does no reliably define the depth of pigment Reflectance confocal microscopy is a more definitve method of doing so. Clinical Assesment of melasma is done through MASI (Melasma Area Severity Index) Melasma (Chloasma) (Pregnancy Mask): Differential Diagnosis: Post-inflammatory hyperpigmentation (PIH) Drug-induced (minocycline…) Frictional…
