Izikhathi zivame ukuhlala phakathi kwemizuzu engama-20 kuya kwengama-30, kanye nokuvama okuphindwe kabili kuya kathathu ngesonto ukuze kutholakale imiphumela emihle. Odokotela kufanele bakhe izinqubo ezizimele ezifaka impendulo yesiguli futhi ziqaphe inqubekela phambili eduze. Ukubhalwa kwezimpendulo zokwelashwa nakho kusiza ekulungiseni izinqubo ngokuhamba kwesikhathi.

#### Ucwaningo Olusafufusa

Ucwaningo oluqhubekayo luyaqhubeka nokuhlola amandla aphelele kanye nokuguquguquka kwe-PDT ngemishini ye-LED enemibala eminingi. Esinye isici esithakazelisayo kakhulu imiphumela yokusebenzisana yokuhlanganisa ubude obuhlukene bamaza. Izifundo ezintsha ziphakamisa ukuthi ukusebenzisa indlela enemibala eminingi kungathuthukisa imiphumela yokwelapha yezimo zesikhumba ezahlukahlukene, okuholela ekuthuthukiseni impilo yesikhumba iyonke. Isibonelo, izivivinyo zemitholampilo seziqalile ukuphenya ukusetshenziswa okuhlangene kwezindlela zokwelapha ze-LED ezibomvu neziluhlaza okwesibhakabhaka ukuthuthukisa ukwelashwa kwezinduna, okuholela ezinzuzweni ezimbili zokunciphisa ukuba khona kwamagciwane ngenkathi kuthuthukiswa ukuphulukiswa.

Enye indlela yokuphenya igxile ekusetshenzisweni kwe-PDT ekwelapheni amanxeba kanye nokuvuselelwa kwezicubu. Izifundo zokuqala zibonisa ukuthi amaza athile angakhuthaza ukukhiqizwa kwe-collagen futhi asheshise inqubo yokuphulukisa, anikeze amathuba athembisayo okwelapha amanxeba angapheli kanye nokululama ngemva kokuhlinzwa.
