Melasma: Inhibit Over-Production of Neurotrophins

Neurotrophins are protein growth factors that encourage the growth and function of nerve cells. They have been found to be involved in melanin synthesis in melasma. Melanocytes are part of the body’s nervous system. The exact role of neurotrophins is unknown; however, using topical ingredients that inhibit the overproduction of neurotrophins, such as retinoids, may help to prevent future melasma patches from forming.
