Mmene Mungasankhire Zofiira za Dzuwa

Mukudziwa kale kuti kutentha kwa dzuwa ndi koyenera nthawi zonse, osati kungoletsa kutentha kwa dzuwa. Kugwiritsa ntchito khungu kosatha nthawi zonse kumathandiza kuchepetsa kusakala msanga , mdima wandiweyani, kamvekedwe kake khungu, ngakhale khansara ya khungu .

Muli ndi zisankho zambiri tsopano kusiyana ndi kale lonse, makamaka mu chilengedwe cha dzuwa. Koma zosankha zonsezi zingakhale zodabwitsa kwambiri.

Tikukuswetsani kuno, kukuthandizani kusankha bwino kwa dzuwa ndi banja lanu.

(Monga mbali, malonda abwino ndi sayansi ali ndi mawu osiyana kwambiri. Mwachidziwitso, komanso malinga ndi sayansi, zonse zimapangidwa ndi mankhwala: sunscreen, madzi, mitengo, iwe, ndi ine. Pamene tikuyankhula mankhwala okongola, mawu akuti mankhwala amagwiritsiridwa ntchito kutanthauza chinthu chilichonse chopangidwa ndi munthu kapena chosachibadwa. Choncho, pa zolinga zathu tsopano tigwiritsa ntchito mankhwala komanso nthawi yeniyeni yogwiritsira ntchito mofanana.)

N'chifukwa Chiyani Tiyenera Kusankha Zofiira?

Aliyense amene amasankha kupita ndi mawonekedwe a dzuwa amawonekera pazifukwa zawo, koma apa pali ena otchuka kwambiri:

• Kuchepetsa kuchepa kwa mankhwala opangidwa. Anthu ambiri amasankha zowonongeka za dzuwa chifukwa akuyang'ana kuchepetsa kuchuluka kwa mankhwala omwe amawonekera tsiku ndi tsiku. Anthu ena samadalira mankhwala osakaniza mankhwala ndipo safuna kuziyika pakhungu lawo. Posachedwa, zina mwa zosakaniza zomwe zimapezeka mu dzuwa zakuthambo zafufuzidwa. Oxybenzone yasonyezedwa kuti imasokoneza mahomoni, makamaka mu makoswe a labu. Zosakaniza zina zomwe zimagwiritsidwa ntchito popanga mankhwala otchedwa sunscreens zakhala zikugwirizana ndi kusokonezeka kwa homoni kusokonezeka ndi khansa. Apanso, izi zogwiritsidwa ntchito sizinawonetseke kuti ziri zotetezeka. Palibe umboni wosatsimikizirika kuti chilichonse chopanga zogwiritsidwa ntchito pa sunscreen chimavulaza-kwa anthu osachepera.

• Kuchepetsa zotsatira zolakwika pa chilengedwe. Pali umboni wakuti zowonongeka ndi dzuwa zimayipitsa chilengedwe. Kupita ku malo osasunthika a m'mphepete mwa nyanja? Zina zimafuna kuti mugwiritse ntchito zowonongeka zowonongeka , kuti mupewe kuvulaza zinthu zowonongeka.
• Mpweya woteteza dzuwa umasokoneza khungu lanu. Ngati muli ndi khungu lenileni , eczema , psoriasis , kapena kupsa mtima kochokera ku dzuwa , ndiye kuti chilengedwe chingakhale chofunikira kwambiri kwa inu. Zosakaniza zowonongeka pamatope a dzuwa (zambiri pa zomwe zili pang'onopang'ono) sizingayambitse kupweteka khungu kusiyana ndi mankhwala opangira dzuwa. Choncho, anthu omwe ali ndi khungu losavuta akhoza kutetezedwa dzuwa popanda kukhumudwitsa khungu lawo.

Kodi N'chiyani Chimachititsa Kuti Dzuwa Likhale Losangalala?

Mwachidule, ndizo zowonjezera zogwiritsa ntchito muwotchi wa dzuwa zomwe zimatsimikizira ngati masewera a dzuwa ndi achilengedwe kapena ayi. Ku US, titaniyamu ya dioxide ndi zinayi oxide ndizokhazikitsidwa zowonongeka ndi dzuwa zomwe zimavomerezedwa ndi FDA.

Ngati mcherewo amapanga zowonjezera zowonongeka, ndi "zachirengedwe." Ngati lili ndi zowonjezera zokha monga oxybenzone, octinoxate, kapena avobenzone, sikuti ndiwotchi ya dzuwa koma kuwala kwa dzuwa.

Koma, musalole kuti mawu achilengedwe amakupusitseni kuti muganizire kuti mukupeza 100 peresenti ya mankhwala. Ndiwe (zowonjezeka) osati. Kumbukirani, "zachilengedwe" muwotchi wanu wa dzuwa zimangotanthauza zowonjezera zokhazokha. Zosakaniza zonse zapachilengedwe zowonongeka zimatha kupanga zonse.

Kusiyanitsa Pakati pa Chophimba Chokongoletsera cha Organic ndi Zojambula Zachilengedwe

Yankho lalifupi: organic ndi malonda, makamaka komwe makampani okongola ndi nkhawa, ndipo ziribe kanthu ndi zowonjezera zowonjezera mu sunscreen. Kuti tiyankhe mobwerezabwereza, tiyenera kuyang'ana kumene malo ogulitsa zokongola ndi asayansi akugawanikanso.

Scientifically, organic mankhwala ali ndi kaboni. Titaniyamu ya dioxide ndi zinayi oxide alibe mpweya-iwo ali zopangidwira zipangizo.

Zambiri mwazitsulo zopangidwa ndi sunscreen zili ndi kaboni, motero zimakhala zowonjezera Zambiri zomwe zimagwiritsa ntchito popanga dzuwa zimakhala ndi kaboni, kotero zimakhala ndizofunikira.

The FDA alibe ndondomeko yeniyeni yokhudza chomwe chimakhala mankhwala. Choncho, zikuwoneka kuti sizingagwiritsidwe ntchito, koma zowonongeka za dzuwa zimakhala "zopangidwa," ndipo zowonetsera dzuwa zimatha kulembedwa kuti "organic."

Dziwani kuti mankhwala omwe amawotcha ku dzuwa amatanthauza kuti ali ndi mitundu yosiyanasiyana ya tizilombo (tchire wobiriwira, mwachitsanzo) umene unapangidwa popanda mankhwala ophera tizilombo. Organic sikutanthauza kuti mankhwala anu ndi 100 peresenti, osagwiritsidwa ntchito, kapena amagwiritsa ntchito zowonjezera zowonjezera.

Mavitamini a Zinc ndi Titani Dioxide Ndilo Chokhachi Chodziwika Chokha Chogwiritsidwa Ntchito

Monga tanenera poyamba, zinc oxide ndi titaniyamu yowonjezera ndizo zokhazo zothandizidwa ndi FDA kupereka mpweya wanu wachilengedwe wa SPF . Zinc oxide ndi titaniyamu ya dioxide ndi mchere, mwachibadwa imapezeka padziko lapansi. Akatha kulowa muwindo wanu wa dzuwa, apangidwa ndikukonzedwanso.

Mwinamwake mumadziwa bwino ndi mchere. Makolo, mumadziŵa zinc oxide kuchokera ku zinthu zina: ufa wa mwana ndi zokometsera. Zipangizo zamakono zowonongeka zili ndi matani a zinc oxide; Ndicho chogwiritsira ntchito chomwe chimachiritsa ndikuchiritsa pansi kwambiri.

Titanium dioxide imagwiritsidwanso ntchito pakampani yosamalira khungu. Amagwiritsidwa ntchito mmadzimadzi ndi maziko, sopo, lotions, ndi mankhwala opangira mano. Mungazidabwe kuona kuti mumapezeka zakudya zathu, makamaka monga phokoso ndi kutafuna chingamu, kuti tipeze mtundu wopanga yemwe akufuna.

Zojambula Zamasamba Zosiyanasiyana Zimagwira Ntchito Mosiyanasiyana

Zozizira zamasamba zimagwira ntchito mosiyana ndi mankhwala osungira dzuwa. Zosakaniza zowonjezera dzuwa zimatulutsa kuwala kwa dzuwa. Zinc oxide ndi titaniyamu ya dioxide, kumbali inayo, ndi zowoneka ndi dzuwa. Iwo samatenga kuwala kwa UV, amawaletsa. Zili ngati kukhala ndi "zikopa" pang'ono pa khungu lanu kukutetezani ku dzuwa.

Pali zizindikiro zina zogwiritsira ntchito kuwala kwa dzuwa kwa nthawi yaitali kumakupatsani chitetezo chotsutsana ndi photoaging chifukwa, mosiyana ndi zokometsetsa dzuwa, palibe mankhwala omwe amachititsa khungu lanu.

Iwo Ali Opaque Oposa Mavitamini Achilengedwe

Kusiyana kwakukulu kwambiri pakati pa zowonongeka ndi zakuthambo ndi momwe amadziwira pakhungu. Zozizira za dzuwa zimakhala ndi mawonekedwe osiyana komanso osasinthasintha kusiyana ndi zomwe mumakhala nazo pa dzuwa. Anthu ambiri amafotokoza kuti ndizowonjezereka. Zingatenge pang'ono kuchotsa kuti zitha kuzimitsa.

Ngati mumagwiritsa ntchito njira zogwiritsira ntchito zowononga zowonongeka mumatuluka mumphuno mwanu, mungadabwe nthawi yoyamba yomwe mumagwiritsa ntchito kuwala kwa dzuwa. Amachoka pa filimu yosavuta kwambiri pazitsamba zoyera, malingana ndi chizindikiro ndi momwe mukugwiritsira ntchito.

Zinc oxide ndi titaniyamu ya dioxide ndi mchere wodetsedwa kwambiri, womwe, mwachibadwa chawo, samalowa mu khungu. Mmalo mwake, iwo amakhala pamwamba kuti atseke dzuwa. (Talingalirani za omvera akale a sukulu ndi oyera pamtunda mlatho wa mphuno-ndiyo zinc oxide.)

Zamagetsi zomwe zili ndi micincidenti ya zinc oxide kapena titanium dioxide zidzakanikirana bwino moyenera komanso moyenera mu khungu. Ngati sakutha kwathunthu, amabwera bwino kwambiri.

Mchere wa micronzedwe umakhala wofiira komanso wochepa kwambiri, choncho sadziwika bwino pakhungu. Koma izi sizitsutsana.

Ngakhale kuti zinc oxide ndi titaniyamu ya dioxide sizitha kulowa m'thupi lawo, pamene malo okhala aang'ono-size particles (otchedwa nanoparticles ) amatha kulowa m'thupi. Zotsatira zomwe zingakhale nazo pa thanzi lathu, ngati zilipo, sizinaphunzirepo mokwanira monga momwe ziliri pano. Anthu ena amakonda kupewa nanoparticles chifukwa cha izi.

Mafuta Ophimba Sadzakutetezani Kuchokera ku Dzuwa

Panthawi imeneyi, makamaka ngati muli ndi chidwi kwambiri, mungakhale mukuganiza kuti mukupanga masewera a dzuwa paokha. Mwamwayi, palibe njira yeniyeni yochitira izi ndipo onetsetsani kuti mukupeza SPF muyenera kuteteza khungu lanu.

Mosiyana ndi zomwe ma blogi ambiri, mavidiyo a pa intaneti, ndi zina zotero zimatha kunena, palibe mafuta omera, mafuta ofunikira, zitsamba, ndi zina zotero zomwe mungagwiritse ntchito khungu lanu kuti akupatseni dzuwa kuteteza. Inde, zowona kuti zomera zina zimakhala ndi luso lachilengedwe la dzuwa. Mafuta a kokonati ndi red rasipiberi mbewu ya mafuta ali ndi mphamvu zowononga mazira a UV , mwachitsanzo. Koma ndizochepa , kupereka SPF 7 pokhapokha komanso SPF 1 poipa kwambiri.

Komanso, mafutawa sakulepheretsa UV kumalo abwino. Mwachidule, iwo akulola kuwala kwa moto ndi kutentha kupyola kudutsa, osapanga kalikonse kuteteza khungu lanu. Magwero omwe mafukufukuwa adanena awonetsetsa kuti mafutawa ali ndi luso la kuwonetsetsa dzuwa ndipo angagwiritsidwe ntchito ngati maswiti a dzuwa, makamaka momveka bwino, osasanthula deta. Choncho, tambani izi DIY mankhwala kuti muteteze khungu lanu.

Mndandanda wazowonjezera 4 wa Kusankha Zojambula Zachilengedwe

Tsopano muli ndi chidziwitso chogwira bwino ntchito za maswiti a dzuwa ndi momwe amagwirira ntchito. Kodi mwakonzeka kusankha choyenera chanu? Mndandanda umenewu udzakuthandizani:

1. Yang'anani zogwiritsidwa ntchito. Mukufuna kwambiri zinc oxide, kaya nokha kapena titaniyamu ya dioxide. Zinc oxide amapereka SPF, ndipo imakuteteza ku mazira a UVA ndi UVB. Titanium dioxide imakhala yothandiza kwambiri polimbana ndi UVB kokha, kotero sikudzakutetezani kudutsa lonse ndipo siziyenera kugwiritsidwa ntchito monga choyimira chokha. Koma ikhoza kuthandizira kuti zinc oxide ikwaniritsidwe.
2. Sankhani SPF ya 30 kapena apamwamba. Mudzafuna kuti SPF yanu ikhale ndi 30. Izi zimatsimikizira kuti mumapeza chitetezo chokwanira kwa nthawi yokwanira. SPF ikhoza kupita ku 50+, koma mutangopitirira pa SPF 30 kuwonjezeka kwa dzuwa kumakhala kukuwonjezereka.
3. Onaninso zowonjezera zina ngati mukufuna zonse-zachirengedwe. Palibe malire a zomwe zimapanga zodzikongoletsera (monga mankhwala osamalira khungu ndi zodzoladzola) kapena mankhwala osokoneza bongo (monga mankhwala achitsulo ndi sunscreen). Kotero, ngati mukufuna njira yowonjezera ya dzuwa (ndi mankhwala alionse a khungu pa nkhaniyi) muyenera kufufuza pang'ono. Chifukwa chakuti dzuwa limakhala lopangidwa mwakuthupi silimadzipanga yekha kutentha kwa dzuwa. Galimoto - makamaka zowonjezera zonse zowonjezera kutentha kwa dzuwa-zikhoza kukhala zopangidwa ndi zopangira. Izi sizikutanthauza kuti kuwala kwa dzuwa kulibwino kapena koipa kuposa ena. Izo zimangobwera chabe ku mtundu wa mankhwala omwe mukuwusaka ndi zomwe mumakonda.
4. Sankhani ngati mukufuna mankhwala opangidwa ndi micronous kapena non-nanoparticles . Chogulitsa chomwe chimatchedwa micronized , kaya kutsogolo kapena m'magulu opangidwira, chidzakupatsani khungu la dzuwa lomwe limatulutsa bwino kwambiri ndipo limasiya kuwala khungu. Izi zidzakupatsani zotsatira zomalizira zomwe zikuwoneka ndikumverera ngati zowonjezera zowonjezera zomwe mungagwiritsidwe ntchito. Komabe, mankhwala osagwiritsa ntchito microni kapena osakhala nano adzasiya filimu yoyera pamwamba pa khungu limene simungathe kulisakaniza. Koma, ngati mukudandaula za kuthekera kwa thanzi la nanoparticles, izi zikhoza kukhala malonda ovomerezeka kwa inu.

Mawu Ochokera

Pali zambiri zambiri zokhudzana ndi kuteteza dzuwa ndi dzuwa, zonse zachirengedwe komanso zachilengedwe. Kungakhale nkhani yosokoneza, chifukwa chakuti pali zambiri zotsutsana komanso zambiri zomwe mungagwiritse ntchito.

Kumbukirani kuti zabwino kwambiri za dzuwa ndi zomwe mumakonda, ndipo zimakhala bwino pakhungu lanu chifukwa ndizogwiritsidwa ntchito. Ndipo ndigwiritsire ntchito khungu lanu la dzuwa nthawi zonse kuti likhale chitetezo chabwino.

Ngati mukufunikira thandizo posankha mankhwala, funsani dokotala wanu kapena dermatologist pazomwe akupempha.
