Unyango lokukhanya okubomvu lwahluke kakhulu kwezinye iindlela zonyango ezinemibala nezisebenzisa imisebe yokukhanya ezisetyenziselwa ukunyanga ulusu, ingqondo kunye neengxaki zomzimba. Nangona kunjalo, unyango lokukhanya okubomvu luthathwa njengonyango olukhuselekileyo noluthembekileyo ngakumbi kunamayeza, ukusetyenziswa kwamaqhinga akudala, utyando kunye nezinye iimveliso eziphilisa ulusu kunye neengxaki zengqondo ngokukhawuleza. Iimveliso zobuhle zikwaluncedo ekukhanyiseni nasekubuyiseleni ulusu ekulimaleni, kodwa zonke ezi ndlela zinokuba nemiphumo emibi engapheliyo kunye neengxaki zempilo.
Yiyo loo nto; unyango lokukhanya okubomvu lusetyenziselwa ukunyanga iingxaki ezininzi zolusu lwangaphandle kunye noxinzelelo lwengqondo. Kwelinye icala, kukho izinto ezibalulekileyo kunye nezizathu ezinxulumene nokuba kutheni abantu belufuna olu nyango. Okokuqala, xa ubushushu obubandayo butshabalalisa ulusu, umbala kunye nokuthamba, uninzi lwabantu lukhetha ukusebenzisa iimpawu zobuhle, kodwa eneneni unyango lokukhanya okubomvu lunokuba lubiza kancinci, lukhuselekile, lungcono kwaye luthembeke ngakumbi kunezi mveliso. Okwesibini, olu nyango luneziphumo ebezingalindelekanga, kodwa alubi yingozi kangako njengoko amayeza kunye neekhrimu zinjalo. Okwesithathu, lunyango oluhle kakhulu noluvunyiweyo ngovavanyo oluya kukhanyisa ulusu kwaye ludlale indima ekufumaneni izizathu zokulwa nokwaluphala. Okokugqibela, lunika iziphumo ezingcono ngexesha elifutshane. Unyango lungqinwa ngokwezonyango ukuze kuveliswe kwaye kukhuthazwe ngokukhawuleza i-collagen.
