Tikukulangizani kuti chitetezo cha padzuwa ndi njira imodzi yabwino kwambiri yopewera kukalamba msanga kwa khungu lanu ndipo chiyenera kukhala chitetezo chanu choyamba tisanapeze zinthu zolimba kwambiri zosamalira khungu. Koma makasitomala amati savala zoteteza ku dzuwa chifukwa ali ndi nkhawa zokhudzana ndi chitetezo cha zosakaniza zomwe zili muzinthu zoteteza ku dzuwa.
Ngati simukudziwa, pitirizani kuwerenga kuti mudziwe kusiyana pakati pa mafuta a suncream a mankhwala ndi a thupi (mineral) komanso chifukwa chake timaganiza kuti mafuta a suncream a mchere ndi abwino kwambiri kugwiritsa ntchito pakhungu lanu.
Koma choyamba, ndikofunikira kufotokoza bwino mawu akuti mankhwala chifukwa nthawi zina pamakhala lingaliro lolakwika lakuti mankhwala onse ndi owopsa. Komabe, ife, ndi chilichonse chozungulira ife timapangidwa ndi mankhwala, ngakhale madzi ndi mankhwala mwachitsanzo, kotero palibe chomwe chingatchulidwe kuti chilibe mankhwala. Pamene pali mantha okhudza zosakaniza zosamalira khungu, izi nthawi zambiri zimakhudzana ndi chinthu chopangidwa ndi mankhwala owopsa. Pankhaniyi, tingagwiritse ntchito mawu akuti, 'opanda poizoni' powonetsa zinthu zomwe nthawi zambiri zimavomerezedwa kuti ndizotetezeka kugwiritsa ntchito.
Kodi mafuta oteteza ku dzuwa omwe amapangidwa ndi mankhwala ndi chiyani?
Mafuta oteteza ku dzuwa amagwira ntchito polowa m'khungu ndipo pamene kuwala kwa UV kukakhudzana ndi suncream, pamakhala kusintha komwe kumachotsa kuwala kwa UV pakhungu lanu musanawonongeke. Amatchedwa mankhwala, chifukwa chakuti pali kusintha kwa mankhwala komwe kumachitika kuti apereke chitetezo ku dzuwa.
Zosakaniza zomwe zimagwiritsidwa ntchito kwambiri ndi oxybenzone, avobenzone, ndi octinoxate ndipo ngakhale mayina awo ndi ovuta kuwatchula, zosakanizazi zimagwira ntchito ngati siponji kuti zinyamule kuwala koopsa kwa ultraviolet.
Kodi mafuta oteteza ku dzuwa okhala ndi mchere ndi chiyani?
Mafuta oteteza ku dzuwa okhala ndi mchere ndi ofanana ndipo amakhala pamwamba pa khungu ndipo amagwira ntchito ngati chotchinga chenicheni ku kuwala kwa dzuwa. Mafuta oteteza ku dzuwa okhala ndi zosakaniza ziwiri zazikulu zachilengedwe - zinc oxide ndi titanium dioxide - ndipo nthawi zambiri amakhala ndi zosakaniza zochepa kuposa mafuta odzola omwe amapangidwa ndi mankhwala.
Kodi mungadziwe bwanji ngati mafuta oteteza ku dzuwa ndi amchere kapena a mankhwala?
Mukhoza kudziwa mtundu wa mafuta oteteza khungu omwe muli nawo potembenuza botolo kapena botolo ndikuyang'ana mndandanda wa INCI (zosakaniza) kumbuyo kwa phukusi kuti muwone ngati pali zosakaniza zomwe zimagwira ntchito.
N’chifukwa chiyani muyenera kusankha mafuta oteteza ku dzuwa?
Monga tanenera pamwambapa, anthu ena ali ndi nkhawa yokhudza zosakaniza zoopsa zomwe zimapezeka mu mafuta a suncream a mankhwala ndipo amakonda kugwiritsa ntchito ma SPF a mineral chifukwa amakhala pamwamba pa khungu m'malo molowa m'thupi. Kupatulapo zosakaniza, mitundu ya khungu yofooka, kapena omwe ali ndi vuto la mafuta odzola padzuwa kapena omwe ali ndi ziphuphu angakondenso zosakaniza zofewa zomwe zimapezeka mu mafuta a suncream a mineral ndi mndandanda wa zosakaniza zazifupi.
Kenako pali kuthekera kogwiritsa ntchito. Ngati mukufuna kutuluka nthawi iliyonse, mungakonde kugwiritsa ntchito mafuta odzola a mineral chifukwa, mosiyana ndi mafuta odzola a sunscreen, omwe ayenera kulowa m'thupi lonse asanayambe kugwira ntchito (amatenga mphindi 15), mafuta odzola a mineral amagwira ntchito akangogwiritsidwa ntchito.
Ubwino wa mafuta odzola dzuwa ochokera ku mchere
Yosalowa madzi ikagwiritsidwa ntchito pakhungu - ndi mafuta a dzuwa a mankhwala kapena amchere muyenera kupakanso mukatuluka mu dziwe kapena m'nyanja.
Chitetezo cha UVA ndi UVB - zinc oxide, chomwe chimagwiritsidwa ntchito mu mineral suncream, chimatha kujambulidwa mosavuta kotero chimapereka chitetezo chabwino cha UVA ndi UVB chifukwa sichidzataya mphamvu yake yoteteza ikakhudzidwa ndi kuwala kwa UV. Izi ndizofunikira popewa kukalamba msanga komanso mavuto azaumoyo wa khungu. Titanium dioxide imapereka chitetezo chochepa cha UVA kotero mudzawona zinc oxide nthawi zambiri pamndandanda wazosakaniza za mineral suncream.
Zotetezeka komanso zosawononga chilengedwe - zosakaniza zofunika kwambiri mu mafuta ambiri a dzuwa omwe amapangidwa ndi mankhwala amatha kuvulaza zamoyo zam'madzi ndi miyala yamchere pomwe zosakaniza zazikulu za mineral suncream nthawi zambiri zimaganiziridwa kuti ndizosamalira chilengedwe ndipo sizingayambitse kuyera kwa makorali kapena kuwononga zamoyo zam'madzi.
Zinc oxide imagwirizana ndi maubwino angapo azaumoyo - Imatha kuchepetsa kuyabwa (ndibwino ngati mwapsa pang'ono ndi dzuwa), sidzateteza ma pores chifukwa siimayambitsa matenda a comedogenic ndipo mphamvu zake zotsutsana ndi mabakiteriya komanso zotupa zimatha kusunga kulimba kwa khungu, mawonekedwe a makwinya komanso kuthandiza kulimbana ndi ziphuphu.
Tikukhulupirira kuti blog iyi yakuthandizani kumvetsetsa kusiyana pakati pa zinthu zosiyanasiyana zoteteza ku dzuwa zomwe zilipo.
