I te whitu o, haere te iwa o te whakautu inflammatory te ra, hei utu puta tan. radiation poipoi poto tere whakapataritari erythema, mahue he ähua ngawari.

chromogenic Mōrahi pāngia e te hihi UV roa-poipoi. I roto i te melanoblast kei roto i te kahu basal o nga kiriwaho, i tyrosine, me ngā hua pirau i hanga melanin Adrenaline dihydroxyphenylalanine. Tona (melanin) rāpoi nui ārai tomo hohonu ki te kiri whatiwhatinga o ngā rāpoi ngota pūmua huna e UV radiation. I tua atu, i te rāpoi ngota melanin mimiti hihi pōkākā , me te tūāwhiorangi kitea. Ko te kupu, tiakina te kiri kei i pukā me tahu. I roto i ngā wāhanga o te mana o hihi katinga nui haere te waitinana, ka pai ake te rere toto te cover houtanga, nui haere ariā o muka collagen. A, no te erythema kaha e rerengia ana roa'tu, e puta ana te ume nei me chronically tukanga inflammatory.

Kei te whānui whakamahia hihi katinga puaretanga i cosmetology. Na, i roto i te solarium he maeneene, me te ataahua tan. whakamahi te reira i hihi roa-poipoi, i te poto-a reo-radiation i roto i salons tanning he whiriwhiringa.

Me kï reira e te rongo nui ki te ra e taea arahi ki hoholo taimi halá, he hekenga i roto i te elasticity o te kiri. I tua atu, kia te whakahohe reira i te hanganga o te Radicals free e whai wāhi ana ki te mate pukupuku.

Hei whakatau i te raina i waenganui i "kino" me "painga" whakamahi te taupū ra UV. Tenei tawhā tohu te taumata o te radiation i runga i te whenua.
