Ochwepheshe bokunakekelwa kwesikhumba bayavuma ukuthi ukwelashwa ngokukhanya okubomvu kuyazuzisa. Ngisho noma le nqubo inikezwa ezindaweni zokushiswa kwesikhumba, ayisondele nhlobo ekutheni ukushiswa kwesikhumba kuyini. Umehluko oyinhloko phakathi kokushiswa kwesikhumba nokwelashwa ngokukhanya okubomvu uhlobo lokukhanya abalusebenzisayo. Nakuba imisebe ye-ultraviolet (UV) enzima isetshenziswa enkambisweni yokushiswa kwesikhumba, ukukhanya okubomvu okuthambile kuyadingeka ekwelashweni ngokukhanya okubomvu. Ngenxa yalokho, odokotela besikhumba bayeluleka kakhulu ngokumelene nokushiswa kwesikhumba.
Izindleko zemibhede yokwelapha ngokukhanya okubomvu kanye nokwelashwa kuncike kakhulu kulokho okwelaphayo, indawo okuyo, nokuthi ufuna ukwelashwa kuchwepheshe wezempilo noma uziphathe usebenzisa idivayisi yokwelapha ngokukhanya okubomvu. Ngokuvamile, lindela u-$25 kuya ku-$200 ngokwelashwa ngakunye; kodwa ukwelashwa ngokukhanya okubomvu ekhaya kungaba ngcono kakhulu ngokuhamba kwesikhathi.
