Ngamafuphi, ukwelashwa kokukhanya okubomvu kusebenza ngokuvuselela izinqubo zamandla eseli, ukuthuthukisa ukujikeleza kwegazi, nokukhuthaza ukukhiqizwa kwe-collagen—izindlela ezisekela isikhumba esinempilo kanye nokunciphisa imigqa emincane ngokuhamba kwesikhathi. Ubufakazi bezokwelapha kanye nokuhlangenwe nakho kweziguli ngokuvamile kusekela ukusetshenziswa kwayo njengesithasiselo esiphephile, esingahlaseli emikhubeni yokunakekelwa kwesikhumba esunguliwe, yize imiphumela incike kakhulu ekwelashweni okuhambisanayo, okulinganiswe kahle.

Njenganoma iyiphi indlela yokwelapha, ukuqonda imikhawulo, ukubeka ukuphepha phambili, kanye nokugcina amathemba angokoqobo kubalulekile ekwanelisekeni kwesikhathi eside. Ukuhlanganisa ukwelashwa kokukhanya okubomvu nokunakekelwa kwesikhumba okunempilo, ukuvikelwa kwelanga, kanye nesiqondiso sochwepheshe kukhulisa izinzuzo futhi kukubeka njengethuluzi eliwusizo esulweni eliphelele lempilo yesikhumba.
