MELAZMA KASALLIGIDA ULTRABINAFSHA NURLARINING ROLI VA PROFILAKTIK GIGIYENA CHORALARINING SAMARADORLIGI
Abstrak
Melazma — terining yuzaki va dermal qatlamlarida giperpigmentatsiya bilan namoyon bo‘ladigan surunkali pigment buzilishi bo‘lib, ko‘pincha yuzning markaziy qismlarida paydo bo‘ladi. Kasallik asosan reproduktiv yoshdagi ayollarda uchraydi va ko‘plab omillar, jumladan ultrabinafsha (UV) nurlari, gormonal o‘zgarishlar hamda genetik moyillik uning rivojlanishida muhim rol o‘ynaydi (1,11,10). UV nurlarining ta’siri melazma rivojlanishining asosiy tashqi omili hisoblanadi, chunki ular melanogenez jarayonini rag‘batlantiradi. Shuningdek, terining pigmentatsiyasi mavsumga qarab o‘zgarib, yoz oylarida kuchayishi kuzatiladi
