Qaphela kakhulu uma udinga ukusebenzisa:

Ngenkathi ilanga lingadala futhi i-hyperpigmentation ngokwalo, ukuvezwa kwelanga okungeziwe kungaphazamisa amabala. Njalo hlola izithako zemikhiqizo emisha ukubona ukuthi azikho yini izithako ezingadala ukuzwela kwelanga.

Lapho kufanele futhi ungasebenzisi imikhiqizo yakho

Sikubambile. Okokuqala akukhathalekile ukuthi usebenzisa ini, vikela isikhumba sakho nge-sunscreen yansuku zonke, ebanzi.

1. Ngabe kufanele ugweme izithako ze-photosensitizing lapho libalele?

Okuphuma ku-Vitamin A (retinol, tretinoin, isotretinoin) kanye (ne-glycolic acid, i-lactic acid, i-mandelic acid) yenza ukwandisa ukuzwela kwakho kwelanga. Namathela ekusebenziseni ebusuku futhi ulandele njalo nge-sunscreen yansuku zonke.

Kungani kubaluleke kangaka ukuvimbela imisebe yelanga

Sikuncomile Kanjani ukuzivikela, kepha ingxenye yempi yokuqapha inqubo yakho ukuqonda ngani.

Ukulimala kwelanga akukhona nje kuphela ngezimpawu ezibonakalayo, izindawo, kanye nezimpawu zokuguga - uLorstcher uxwayisa ngokuthi imisebe i-carcinogenic. “[Bacindezela] nemisebenzi ethile yamasosha omzimba, idlala indima enkulu ekuthuthukiseni umdlavuza wesikhumba.”

Yebo, womabili ama-UVA ne-UVB angumdlavuza weqembu, futhi asebenza zombili izinhlangothi ukwenza kwenzeke. Ngenkathi i-UVB ishisa isikhumba sakho, i-UVA ingena isinyonyobele esikhunjeni sakho ngaphandle kwezimpawu zokuxwayiswa ngokushesha.

Umonakalo wesikhumba odalwe yimisebe ye-UVA:

• ukujula
• imibimbi
• ukulahleka kwesikhumba ukuqina
• isikhumba esincanyana nesiguquguqukayo
• ama-capillaries aphukile
• izindawo zesibindi noma zeminyaka
• isikhumba esomile, esirhabaxa nesikhumba
• umdlavuza wesikhumba

Futhi, kukhona umonakalo ezingeni lamangqamuzana: Kungenzeka ukuthi uzwile ngama-radicals wamahhala (nokubaluleka kwama-antioxidants) kepha abantu abaningi abazi ukuthi imisebe ye-UVA idala la ma-radicals wamahhala alimazayo. Lokho kusho ukuthi isikhumba esishukiwe siphambene nesikhumba esinempilo - yisikhumba esilimele. Kuwuphawu lokuthi umzimba wakho uzama ukuvikela ekulimaleni okuqhubekayo kwe-DNA.

"Ukuchayeka isikhathi eside kwe-UVA kulimaza imicu ye-collagen [esikhunjeni]," kuchaza uLortscher. “Akuzona izinsuku ezinde kuphela ebhishi ezibangela ukuguga okubonakalayo. Ukuchayeka kwe-UVA kwenzeka njalo lapho uya emotweni, usebenza ngaphandle ngezinsuku ezinamafu, noma uhlala ngisho ngasewindini. ”

Ngakho-ke manje unayo - ungaguqula ukulimala kwelanga okubonakalayo ngayo yonke imikhiqizo esekelwa yisayensi etholakalayo, kepha njengoba uLortscher esho: “[Uma] ungavikeli [elangeni], ngakho-ke asikho isidingo sokubheka imikhiqizo phatha izindawo ezineminyaka yobudala nezinye izinhlobo zokweqisa ngokweqile, njengoba ulwa impi enganqobiyo! ”
