① ʻO ka helu haʻahaʻa, ʻoi aku ka palekana o kēia mea hana.
ʻO ke ʻano o ka sunscreen kemikala ka absorption a me ka hoʻololi ʻana. Hiki i nā pūhui organik i loko o nā pale lā ke hoʻopaʻa i ka ikehu o ka radiation ultraviolet a hoʻololi iā ia i ka ikehu wela a i ʻole nā ʻano kukui ʻino ʻole. Pono kēia ʻano hana i ka hopena kemika me ka ʻili, no laila hiki i kekahi mau mea pale lā ke hoʻoulu i ka hoʻonāukiuki a i ʻole ka hopena maʻi i ka ʻili. Eia nō naʻe, ʻoi aku ka maikaʻi o ka paʻa a me ka permeability o nā sunscreens kemikala, e hana ana i kahi kiʻi ʻoniʻoni pale a paʻa i ka ʻili, e hāʻawi ana i nā hopena pale ʻoi aku ka maikaʻi o ka lā.
Hāʻawi kā mākou hui i nā mea hoʻoheheʻe UV no ka dermatology / nā huahana mālama ʻili / nā mea hoʻonaninani, e hoʻokō me ka hapa nui o nā mea hoʻonaninani a me nā lāʻau lapaʻau. E loaʻa iā ʻoe kahi pane i loko o 48 mau hola ma hope o ka nīnau.
