N Concordance 1 on, increased epidermal melanocytes and melanin in the epidermis, and scattered 2 thermal damage (vacuolization) of basal melanin granules, pigmented basal melano 3 susceptibility to heat and cold between melanin-deficient cells grown with and w 4 e melanocytes are incapable of boosting melanin production (and who tan poorly) 5 autooxidation and formation of dopamine-melanin. Furthermore, the presence of Bc 6 venge toxic metabolites produced during melanin synthesis.
