Ngo-1998, i-FDA yavuma ukusetyenziswa kwegama kwabanye abavelisi bee-laser zokususa iinwele kunye nezixhobo zokukhanya ze-pulsed.Ukususwa kweenwele zePermament akuthethi ukupheliswa kwazo zonke iinwele kwiindawo zonyango.Ukunciphisa ixesha elide, elizinzileyo kwinani leenwele ezikhula kwakhona emva kolawulo lonyango.
Xa usazi i-anatomy yeenwele kunye nenqanaba lokukhula ngoko Yintoni unyango lwe-laser kwaye lusebenza njani?
IiLaser ezenzelwe ukunciphisa iinwele ngokusisigxina zikhupha amaza okukhanya okufunxwa yimelanin kwifolicle yeenwele (dermal papilla, matrix cells, melanocytes).Ukuba ulusu olujikelezileyo lulula kunombala weenwele, amandla amaninzi e-laser aya kugxininisa kwi-shaft yeenwele (i-photothermalysis ekhethiweyo), ukuyitshabalalisa ngokufanelekileyo ngaphandle kokuchaphazela ulusu.Nje ukuba i-follicle yeenwele itshatyalaliswe, iinwele ziya kuwa ngokuthe ngcembe, emva koko ukukhula kweenwele okuseleyo kuya kuguqukela kwinqanaba le-anagen, kodwa zijike zibe zincinci kakhulu kwaye zithambe ngenxa yokungabikho kwezondlo ezaneleyo zokuxhasa ukukhula kweenwele.
Yeyiphi iteknoloji efanelekileyo kakhulu yokususa iinwele?
I-epilation yekhemikhali yemveli, ukukhupha i-mechanical epilation okanye ukucheba i-epilation nge-tweezer zonke zicheba iinwele kwi-epidermis zenza ulusu lubukeke lugudile kodwa aluchaphazeli kwi-folic yeenwele, yiyo loo nto iinwele zikhula ngokukhawuleza, kwaye zomelele ngakumbi kunangaphambili ngenxa yokuvuselela okubangela ngakumbi. iinwele zibe kumgangatho we-anagen.Ngaphezu koko, ezi ndlela zemveli zinokubangela ubuhlungu bolusu, ukopha, ukuba nengqondo yolusu kunye nezinye iingxaki.Usenokubuza ukuba i-IPL kunye ne-laser zithatha umgaqo wonyango ofanayo, kutheni ukhethe i-laser?
Yintoni umahluko phakathi kweLaser kunye ne-IPL?
I-IPL imele 'i-intense pulsed light' kwaye inomahluko athile anegama elifana ne-SIPL, VPL, SPL, OPT, SHR ezibubuchwephesha obufanayo.Oomatshini be-IPL abayizo ii-lasers ngenxa yokuba oomatshini bayo be-wavelength.IPL enye bavelisa i-wavelength ebanzi enokuthi ifikelele ubunzulu obuhlukeneyo bezicubu zesikhumba, ifunxwe kwiithagethi ezahlukeneyo ikakhulu zibandakanya i-melanin, i-hemoglobin, i-water. ukufikelela kwiziphumo ezininzi ezinjengokususwa kweenwele kunye nokuvuselelwa kolusu, ukususwa kwemithambo yemithambo, ukunyangwa kwamaqhakuva.Kodwa unyango ngokuntyiloza ukuya kwimvakalelo ebuhlungu ngenxa yamandla alo aqinileyo okukhanya okubanzi okubanzi, umngcipheko wokutsha kwesikhumba nawo uya kuba phezulu kunesemiconductor diode lasers.
Umatshini jikelele we-IPL usebenzisa isibane se-xenon ngaphakathi kwiqhekeza leqhekeza elikhupha ukukhanya, kukho isafire okanye ikristale yequartz ngaphambili kwesikhumba sokudlulisa amandla okukhanya kwaye wenze ukupholisa ukukhusela ulusu.
(ukukhanya ngakunye kuya kuba yimveliso enye kubandakanya iipulse ezininzi), isibane se-xenon (umgangatho waseJamani malunga ne-500000 pulses) ubomi buyakuba ngaphantsi ngokuphindwe kaninzi kune-laser bar ye-diode.
(i-marco-channel okanye i-micro-channel jikelele ukusuka kwi-2 ukuya kwi-20 yezigidi) uhlobo. Ngaloo ndlela ii-lasers zokususa iinwele (oko kukuthi i-Alexandrite, i-Diode, kunye ne-ND: iintlobo ze-Yag) zivame ukuba nobomi obude kunye nemvakalelo ekhululekile yonyango lweenwele ezingafunekiyo. Ezi lasers ezikhethekileyo sebenzisa kwiziko lobuchwephesha lokususa iinwele.
