Nokuba kukho imingcipheko, isikhumba esimhlophe mhlophe sithandwa ngakumbi kunangaphambili

Ukwenza mhlophe okanye ukwenza mhlophe sisihloko esinempikiswano enkulu. Inika iindlela ezinomtsalane zokuphucula umbala wakho.
Zininzi iindlela zokwenza ulusu lube lula. Oku kubandakanya iikhrim ezizodwa zolusu kunye nonyango lwe-laser. Ngenxa yexabiso layo eliphantsi kunye nokhuseleko oluphezulu, abantu abaninzi bakhetha iikhrimu zolusu.
Ukuba ucinga ngemveliso emhlophe, kukho izinto ezithile ekufuneka uyazi kuqala. Eli nqaku lichaza ezona zinto zibalulekileyo, ngakumbi izithako.莫诺苯宗
Ukukhanyisa ulusu ngokusisiseko kubhekisa kusetyenziso lonyango olukhethekileyo okanye izinto ukuphucula okanye ukukhanyisa ithoni yolusu. Abantu basebenzisa amagama awahlukeneyo ukuyichaza, kubandakanya ukwenza mhlophe, ukukhanyisa okanye ukwenza mhlophe ulusu.
Ukuvezwa kolusu lomntu kwizinto ezininzi kunokubangela ukuba lube buthuntu. Ukwaluphala, ukungcola, uthuli, ubumdaka, imitha yelanga kunye neekhemikhali (kubandakanya nezo zikwimveliso yokhathalelo lolusu) zinokonakalisa ulusu.
Ukungondleki, ukukhetha impilo ngendlela engafanelekanga kunye noxinzelelo kunokuba nefuthe elibi kwinkangeleko yolusu.
Ezi zinto zahlukileyo zinokubangela iingxaki ezahlukeneyo, kubandakanya izangqa ezimnyama, amabala eminyaka, amabala amabala kunye namabala.
Abantu baxhomekeke kwiimveliso ezimhlophe kunye nonyango ukusombulula ezi ngxaki. Bazisebenzisa ukuphucula okanye ukubuyisela ithoni yolusu.
Ngeemveliso ezikhanyisa ulusu, ungadibanisa iindawo zesikhumba ezi-hyperpigmented kunye nombala wolusu olujikelezileyo. Ezi ndawo zibandakanya iimpawu zokuzalwa, i-moles, i-chloasma kunye neetoni.
Ukukhanya kwesikhumba yinto eyenzeka kwihlabathi liphela, nangona kukho umdla omkhulu ekukhanyeni kolusu eAfrika, Middle East nase India. Ngo-2013, kuqikelelwa ukuba ngo-2018, imveliso yentengiso yolusu olumhlophe iya kufikelela phantse kwiibhiliyoni ezingama-20 zeedola zaseMelika.
