Ngaba i-laser ikhuselekile kwiitoni zesikhumba ezimnyama?

Umatshini wethu wokususa iinwele we-laser wamva nje onamandla aphezulu.Ikhuselekile kwiintlobo zolusu olumnyama kuba ibonelela ngamaza amaza amabini: enye yi-755 nm wavelength kunye ne-1064 nm wavelength.I-1064 nm wavelength, ekwabizwa ngokuba yi-Nd:YAG wavelength, ayifuntshwanga kakhulu yimelanin njengobunye ubude bamaza.Ngenxa yoku, ubude be-wavelength bunokuphatha ngokukhuselekileyo ZONKE iintlobo zesikhumba kuba ibeka amandla ayo nzulu kwidermis ngaphandle kokuxhomekeka kwi-melanin ukwenza njalo.Kwaye ekubeni Nd:YAG idlula i-epidermis, obu bubude buyindlela ekhuselekileyo yolusu olumnyama.

Ngokusekwe kwithiyori ekhethiweyo yokufunxa ukukhanya, sivumela i-laser ye-diode eyenziwe ngumatshini wokususa iinwele we-laser ukuba idlule kumphezulu wolusu kwaye ingene kwiifollicle zeenwele ngokuhlengahlengisa ubude, amandla, kunye nobubanzi be-pulse ukuqonda injongo yokususa iinwele.Kwi-follicle yeenwele kunye ne-hair shaft, kukho i-melanin eninzi esasazeka phakathi kwe-follicle matrix kunye nokufudukela kwisakhiwo se-hair shaft.Nje ukuba i-melanin ithathe amandla e-laser, iya kubonisa ukunyuka okubukhali kobushushu kwaye ikhokelele ekutshabalaliseni izicubu ze-follicle ezijikelezileyo.Ngale ndlela, iinwele ezingafunekiyo ziya kususwa ngokupheleleyo.
