Imfundo yezeMpilo

Ilanga liphumile. Ixesha lifudumele. Kwaye sowuzakubetha elunxwemeni… okanye ipaki… okanye iindlela zokunyuka intaba zosuku lokuzonwabisa. Ngaphambi kokuba uhambe, ubambe ibhotile ye i-sunscreen ukufaka ebhegini yakho-kodwa khawuleza uqaphele ukuba umhla wokuphelelwa ugqithile. Okanye akukho mhla wokuphelelwa udweliswe konke konke. Ngaba i-sunscreen ikhuselekile ukuba ingasetyenziswa? Ngaba iya kukukhusela kwi ukutshiswa lilanga okungathandekiyo ? Okanye ungcono xa uyiphosa kwaye uthenga ibhotile entsha?

Ngaba i-sunscreen iyaphelelwa?

Iscreen selanga siyaphelelwa nyani, kwaye isenokungasebenzi ngokugqithileyo ngalo mhla, ngokwe UJoshua Drafman, MD , Umlawuli kuphando lwezithambiso kunye nonyango kwiklinikhi yesikhumba kwiSibhedlele iMount Sinai kwisiXeko saseNew York

Inqanaba lokhuselo elibhalwe kwibhotile linokuqinisekiswa kuphela ukuya kumhla wokuphelelwa kuluhlu, utshilo. Emva kwelo nqaku, i-sunscreen iya kuthi inike inqanaba elithile lokhuseleko; Nangona kunjalo, ayinyanzelekanga kangako njengoko ibinikile ekuqaleni.

Njengemveliso ethengiswayo, i-sunscreen ilawulwa yi-Food and Drug Administration (FDA) kwaye kulindeleke ukuba umhla wokuphelelwa kwayo uphawulwe kwileyibhile-okanye ubungqina bokuba ubomi bayo beshelfini bube yiminyaka emithathu edlulileyo kumhla wokwenziwa kwayo. Oko kuthetha ukuba, nangasiphi na isizathu, ibhotile yakho elangeni ayinawo umhla wokuphelelwa, kufuneka ilungile ukuya kuthi ga kwiminyaka emithathu emva komhla wayo wokuthenga. Ngaphandle koko, ngekhe ivimbe ezo mitha ze-ultraviolet (UV) ngokunjalo.

Nokuba i-sunscreen yakho ayiphelelwa lixesha, uyakufuna ukuqinisekisa ukuba akukho lutshintsho lubonakalayo kulwakhiwo ukusukela ngexesha lokugqibela ulisebenzise.

Ukuba ayijongi, ayive, okanye ivumba ngendlela eyayenza ngayo xa wawuyithenga okokuqala, kuya kufuneka uyiphose, utshilo uGqirha Zeichner. Andithandi mntu ukuba athathe umngcipheko xa kufikwa kukhuseleko lwelanga.

Ngaba kulungile ukusebenzisa i-sunscreen ephelelwe lixesha?

Umngcipheko omkhulu wokusebenzisa i-sunscreen ephelelwe lixesha kukuba izithako ziya kuphulukana nokusebenza kwazo kwaye unethuba eliphezulu lokutsha. Kodwa zinokubakho ezinye iziphumo kulusu lwakho, utshilo uMarisa Garshick, MD, ugqirha wesikhumba oqinisekisiweyo eNew York Unyango lweDermatology kunye neZiko loPhuculo lweeCosmetic .

Izithsaba-langa eziphelelwe lixesha zinokuziva okanye zibukeke zahlukile kwifom yoqobo kunye nemichiza yelanga ekhusela ioyidingi kunye nokuthintela ulusu ngokwasemzimbeni kuthoba isidima, utshilo. Ukuba ukungaguquguquki kwahlukile, isenokungavakali ngendlela efanayo nesikhumba kwaye lenze ulusu lube novakalelo ngakumbi okanye lucaphuke. Kwangokunjalo, ukuba kukho naziphi na izinto ezisigcinayo eziphelileyo kwaye imveliso iphelelwa lixesha, inokunyusa amathuba eebhaktiriya ezisebhotileni, ezinokuthi zikhokelele kusulelo.

Oko kwathiwa, ukuba usepinkini kwaye ukungaguquguquki kusabonakala kulungile, ukusebenzisa i-sunscreen ephelelwe lixesha akunakuba lolona khetho lubi.

Ndixelela izigulana zam ukuba i-sunscreen ephelelwe lixesha ngokuqinisekileyo ibhetele kunokuba ingekho i-sunscreen kwaphela, utshilo uGqirha Zeichner. Nangona kunjalo, ndiyazithanda izigulana zam ukuba zithenge i-sunscreen entsha rhoqo lonyaka. Ukuba usebenzisa i-sunscreen ngokufanelekileyo, ibhotile oyithengayo ngoSuku lweSikhumbuzo ngokuqinisekileyo ayinakuhlala kude kube lusuku loMsebenzi.

Ukuba i-sunscreen yakho iphelelwe lixesha, kuya kufuneka uyilahle kude. Ngokungafaniyo amayeza kagqirha , akukho ndlela iphakanyisiweyo yokwenene yokulahla ii-sunscreens. Inkqubo yokuqokelela amayeza kwingingqi inokuyithatha, kodwa uninzi aluyamkeli imveliso yokhathalelo lomntu (ethi ithathelwe elangeni). Ukuba ufuna ukuphinda usebenzise ibhotile, thambisa iscreen selanga esingasetyenziswanga kwinkunkuma kunokuba yehle idreyini ukuthintela imichiza engeyomfuneko ekungeneni kunikezelo lwamanzi.

Ukhuseleko kwelanga

Umhlaza wolusu lolona hlobo luqhelekileyo lomhlaza e-U.S, kwaye ukonakala kwelanga kwimitha ye-UV kunokwenzeka kwimizuzu nje eli-15, ngokwe Amaziko oLawulo lweZifo noThintelo . Kungenxa yoko le nto kubaluleke kakhulu ukuziqhelanisa nokhuseleko elangeni unyaka wonke, kubandakanya:

• Ukunciphisa ixesha olichitha elangeni , ngakumbi phakathi kweeyure ze-10 kusasa kunye ne-4 emva kwemini, xa imitha ingamandla.
• Ukumboza kangangoko kunokwenzeka umnqwazi obanzi, izibuko zelanga kunye neehempe ezinemikhono emide okanye ibhlukhwe. Imibala emnyama okanye eqaqambileyo yeyona ilungileyo, ngokwe Isiseko somhlaza wolusu , njengoko befunxa imitha kunokuba bayivumele ingene. Inani leempawu zempahla ngoku zibandakanya ulwazi lwe-Ultraviolet Protection Factor (UPF) -ingakanani imitha ye-UV kwilaphu elibhloka-ekubhaleni kwabo.
• Ukuhlala emthunzini. Iiambrela, iintente kunye nemithi zinokukhusela kakhulu elangeni elishushu.
• Kwaye, ewe, unxibe izithambisi zokhuselo lelanga akunamsebenzi — usenokutsha nasemthunzini.

Ndingayikhetha njani i-sunscreen efanelekileyo?

Iscreen selanga sikhusela isikhumba kwiintlobo ezimbini zemitha: i-UVA kunye ne-UVB. Imitha ye-UVA inxulunyaniswa nokwaluphala kolusu, ngelixa imitha ye-UVB inxulunyaniswa nokutsha kolusu-zombini ezi zinto zinegalelo kumngcipheko womhlaza wolusu.

UVA kunye ne-UVB

Zimbini izikhombisi ekufuneka ujonge kuzo xa uthenga i-sunscreen: Ukuba ileyibhile ithi bubanzi bokubonisa uyazi ukuba ine-UVA kunye ne-UVB. I-SPF (into ekhusela ilanga) ilinganisa inqanaba lokhuseleko lwe-UVB.

I-SPF

Ingcebiso yangoku evela kwiAmerican Academy of Dermatology and Skin Cancer Foundation kukuba ukhethe iscreen elangeni okungenani nge-SPF 30, utshilo uGqirha Zeichner. Ndincoma ngokwam ukuba abaguli bam basebenzise i-sunscreen nge-SPF ephezulu kakhulu. Kwilizwe lokwenyani, asisebenzisi i-sunscreen eninzi njengoko kufanelekile kwaye ngekhe siphinde sisebenzise rhoqo kwiiyure ezimbini. Ngenxa yoko, inqanaba lokhuseleko esilifumanayo lihlanjululwe ngaphandle.

Kukho iimveliso zokhathalelo lolusu ngaphaya kwe-sunscreen ene-SPF, kubandakanya izinto zokuthambisa, i-lip balm, kunye nezithambiso. Nangona kunjalo, ezi mveliso azihlali zikhusela i-UVA, yiyo loo nto kubalulekile ukuba unxibe i-sunscreen.

Amaminerali okanye amachiza

Uyakufuna kwakhona ukuqaphela uhlobo lwe-sunscreen oyithengayo. Zimbini: izimbiwa (ezaziwa ngokuba zezomzimba) kunye neekhemikhali.

Iscreen selanga iqulethe i-zinc oxide okanye i-titanium dioxide kwaye isebenza njengesithintelo emzimbeni ukubonakalisa ilanga (cinga: abagcini-bomi abanomgca omhlophe empumlweni).

Iscreen elangeni , kwelinye icala, lifunxa imitha yelanga njengesiponji kwaye iqulethe enye (okanye ezininzi) kwezi khemikhali zilandelayo: njenge-avobenzone, i-homosalate, i-octisalate, i-oxybenzone, ne-octinoxate. Zombini zinezinto ezilungileyo nezingalunganga, ke ukuba ukhangele eyona sunscreen ilungileyo kuwe, thetha nodokotela wesikhumba.

Nokuba ukhetha ntoni, sebenzisa ubungakanani beglasi yeglasi (malunga neepunipuni ezimbini) kwiindawo ezifihlakeleyo zomzimba nobuso, imizuzu eli-15 ngaphambi kokuba uphume uyinike ixesha lokufunxa. Ukongeza kokufaka isicelo rhoqo emva kweeyure ezimbini, uya kufuna ukunxiba enye idyasi emva kokuqubha okanye ukophula ukubila okunzima, kuba uninzi lweescreen selanga ziya kube zihlambile okanye zathontsiza. Kodwa yoma kuqala-uGqr. UZeichner uthi i-sunscreen ayizukufunxa ngokupheleleyo xa isetyenziswa kulusu olumanzi.

Xa kuziwa ekugcineni i-sunscreen yakho, qiniseka ukuba ikubushushu begumbi, ukuthintela ubushushu obugqithisileyo. Ungayishiyi ihleli elangeni okanye emotweni eshushu, kuba oko kunokuba nefuthe kumandla ayo. Emva koko, ngayo yonke into engqondweni, nwabele usuku lwakho elangeni (okanye kungcono kodwa, umthunzi)!
