elasma is a chronic acquired hypermelanosis of the skin,
characterized by irregular brown macules symmetrically
distributedon sun-exposedareas of thebody, particularlyon the
face. It is a common cause of demand for dermatological care
that affects mainly women and more pigmented phenotypes
(Fitzpatrick skin types III-V). There are some known triggering
factors such as sun exposure, pregnancy, sexual hormones,
inflammatory processes of the skin, use of cosmetics, steroids,
and photosensitizing drugs. The main scope of therapy of
melasma is protection from sunlight and depigmentation.
Pigment reduction is achieved by using chemicals that interfere
with various steps of the melanogenesis pathways via: (i) the
retardation of proliferation of melanocytes; (ii) the inhibition
of melanosome formation and melanin synthesis; and (iii)
the enhancement of melanosome degradation. First-line
therapy usually consists of topical compounds that affect the
melanin synthesis pathway, broad-spectrum photoprotection,
and camouflage. Chemical peels are often added in second-
line therapy. Laser and light therapies represent potentially
promising options for patients who are refractory to other
modalities, but also carry a significant risk of worsening the
disease.
