(Funga vafambisi vane mutsetse muchena pasi pemhino.)

Neraki, vagadziri vazhinji vakapokana neizvi nekugadzira mafomula ane nanoparticles, ayo anobatsira iyo chena titanium dioxide inotaridzika yakajeka uye chaizvo inopa zviri nani SPF dziviriro - asi pamutengo wekudzivirira kwakanyanya kweUVA, anodaro Dr. Jacknin. Sezvineiwo, fomula ine chiyero chehombe zinc oxide zvidimbu zvekudzivirira kukuru kweUVA, uye diki titanium dioxide zvidimbu kuitira kuti chigadzirwa chienderere mberi chakajeka.

(Pro tip: Kana uine ganda rinonzwa, tsvaga mabhodhoro akanyorwa kuti vana, Dr. Bodemer shares.) Kana iri yezvisingashandiswi, Dr. Bodemer anokurudzira kutsvaga mabhodhoro akanyorwa kuti "sport" kana "water resistant" pane kuti aite chigadziko chaicho. , sezvo izvi zvichizogara kwenguva refu kuburikidza ziya uye nemvura. Uye nepo vazhinji vedu tichidzidziswa kutsvaga SPF, kunyangwe iyo FDA inodana yakakwira SPF "inotsausa zvakasikwa." Iyo EWG inotaura kuti inoshanda zvakanyanya kushandisa yakaderera SPF sunscreen zvakanaka pane yakakwirira hafu-moyo.

(FYI heano dzimwe sarudzo dzezuva dzakasimuka kune yedu sweat test.)

Uye kunyangwe zvingave zvakanyanya kunetsa kuisa, iwe zvirinani kunamatira kune lotion-iwo nanoparticles ayo anoderedza chalk kazhinji anochengeteka, asi anogona kukonzera kukuvara kwemapapu kana iwe ukaaputira iwo kubva kune fomura fomati, Dr. Jacknin anowedzera. Chimwe chakakosha kunyorera FYI: Nekuti chicherwa chezuva chinodzivirira nekugadzira chipingamupinyi, iwe unoda kuunganidza maminetsi gumi nemashanu kusvika makumi maviri usati wabuda kunze-usati watanga kufamba uye kudikitira-kuona kuti une firimu rakaenzana paganda rako kana uchinge warova zuva. , Dr. Bodemer vanodaro. (Kune mhando yemakemikari, iise pamaminitsi makumi maviri kusvika makumi matatu zuva risati rabuda kuitira kuti ive nenguva yekunyura mukati.)

Iyo EWG inoyera mhando yega yega yezuva kuti ishande uye chengetedzo, saka tarisa dhatabhesi yavo kuti uone painowira fomura yako yaunofarira. Mamwe mashoma emakemikari atinoda anosangana nemitemo yederms uye iyo EWG: Beyond Coastal Active Sunscreen, Badger Tinted Sunscreen, uye Neutrogena Sheer Zinc Dry-Touch Sunscreen.
