Izifundo zamva nje ziye zaqwalaselwa kunxibelelwano phakathi kokuvezwa kwi-Ultraviolet (i-UV) kunye nophuhliso lweengqukuva ze-pitation kwilusu. Abaphandi bakudala bazi ukuba imitha ye-UV evela kwiLanga inokubangela i-sunburns kwaye yandise umngcipheko womhlaza wolusu. Nangona kunjalo, iqumrhu elikhulayo lomzimba licebisa ukuba ezi rayi zinokwenza ukubangela ukuveliswa kwe-melanin, i-pigment enika ulusu lwayo, olukhokelela ekubonakalisweni kwamabala amnyama okanye amachaphaza esikhumba.
Enye into ephazamisekileyo yophawu oluqhelekileyo olukholelwayo ukuba lunxulunyaniswa nokuvezwa kwe-UV ngu-Melasma, okwabizwa ngokuba yi-chlosma. Le meko ibonakaliswa kukuphuhliswa kweziqwengana ezimdaka okanye ezingwevu ebusweni, ngokufuthi kwipateni yendlela yokulinganisa, kwaye idla ngokubonwa kubafazi. Ngelixa eyona nto ibalulekileyo ye-melasma ayaziwa, abaphandi bakholelwa ukuba iihomoni, imitha yemfuza, kunye ne-radiation ye-UV yonke igalelo.
Olunye uhlobo lokuphazamiseka kwe-pitation olunxulunyaniswa nokuvezwa kwe-UV kukuveza i-PromolPigimetion (PIH). Oku kwenzeka xa ulusu lubangelwa, njengakwimeko ye-acne okanye i-Eczema, kunye ne-melanocyte kwinkalo echaphazelekayo ivelisa i-melanin engaphezulu. Ngenxa yoko, ii-tychendo eziphumeleleyo okanye amabala anokuhlala esikhumbeni emva kokuvuvukala.
Ubudlelwane phakathi kwe-UV ye-UV kunye nengqokelela ye-pitation igxininisa ukubaluleka kokukhusela ulusu kwizinto eziyingozi zelanga. Oku kunokwenziwa ngokunxiba iimpahla ezikhuselayo, ezinje ngehempe yezambatho ezinde kunye neminqwazi, kwaye kusetyenziswe i-scycreen nge-spf ubuncinci ilanga, ngakumbi ngexesha le-UV Index iphezulu.
Kwabo sele benengxaki yokuphazamiseka, kukho unyango olukhoyo olunokukunceda ukunciphisa ukubonakala kwamabala amamnyama okanye iziqwengana. Oku kubandakanya iikhrim eziphezulu eziqukethe izithako ezinje nge-hydroquinone okanye i-retinoids, iipilisi zekhemikhali, kunye nonyango lwase-laser. Nangona kunjalo, kubalulekile ukuba usebenze nengcali ye-dermatologist ukufumanisa eyona khosi ilungileyo yonyango, njengoko ezinye iindlela zinokungalungelanga iintlobo ezithile zolusu okanye zinokubangela iziphumo ebezingalindelekanga.
Ngelixa ubudlelwane phakathi kwe-UV kunye nezaphulelo ze-pitation zinokubakho, kubalulekile ukukhumbula ukuba ayizizo zonke iintlobo ze-pigment ziyingozi okanye zibonisa umcimbi omkhulu wezempilo. Umzekelo, i-freckles, ezinamaqela e-melanin ebonakala eluswini, ayinabungozi kwaye ayifuni kunyango.
Ukuqukumbela, uqhagamshelo phakathi kwe-UV ye-UV kwayeukuphazamiseka kwe-pigmentigxininisa ukubaluleka kokukhusela ulusu ukusuka kwilanga eliyingozi lelanga. Ngokuthatha amanyathelo alula ngokukhuselekileyo njengokunxiba iimpahla ezikhuselayo kunye nokusebenzisa i-suncfuen, abantu banokunceda ukunciphisa umngcipheko wabo wokuphuhlisa ukuphazamiseka kwe-pitation kunye neminye imibandela yesikhumba esinxulumene nelanga. Ukuba kuvela izinto ezixhalabisayo, kubalulekile ukuba unxibelelane ne-dermatologist ukufumanisa eyona ndlela ilungileyo yonyango.
