Muna 1998, FDA yakabvumidza kushandiswa kweshoko iri kune vamwe vagadziri vema lasers ekubvisa bvudzi nemidziyo ye pulsed light. Kubvisa bvudzi zvachose hazvirevi kubviswa kwebvudzi rese munzvimbo dzekurapa. Kudzikira kwenguva refu uye kwakagadzikana kwehuwandu hwebvudzi hunokurazve mushure mekurapwa.
Kana uchiziva hunhu hwebvudzi uye danho rekukura, saka chii chinonzi laser therapy uye inoshanda sei?
MaLaser akagadzirirwa kuderedza bvudzi zvachose anoburitsa chiedza chinotorwa ne melanin mu folicle yebvudzi (dermal papilla, matrix cells, melanocytes). Kana ganda rakatenderedza rakajeka kupfuura ruvara rwebvudzi, simba re laser rinozopinda mu hair shaft (selective photothermalysis), richiriparadza pasina kukanganisa ganda. Kana follicle yebvudzi yaparadzwa, bvudzi rinodonha zvishoma nezvishoma, ipapo basa rekukura kwebvudzi rinozoshanduka kuita anagen stage, asi rinozoshanduka kuita rakatetepa uye rakapfava nekuda kwekushaya zvinovaka muviri zvakakwana zvinotsigira kukura kwebvudzi.
Ndeipi tekinoroji yakakodzera kubvisa bvudzi?
Kuchekwa kwebvudzi nemakemikari, kuchekwa kweganda nemechanical epilation kana kugerwa netweezer, zvese zvinochekwa bvudzi paganda zvinoita kuti ganda ritaridzike zvakanaka asi hazvikanganisi folicle yebvudzi, ndosaka bvudzi richikura nekukurumidza, rakasimba kupfuura kare nekuda kwekukurudzira bvudzi kuti ripinde muchikamu che anagen. Uyezve, nzira idzi dzechinyakare dzinogona kukonzera kukuvara kweganda, kubuda ropa, kunzwa kweganda nezvimwe zvinetso. Ungabvunza kuti IPL ne laser zvinotora nzira imwe chete yekurapa, sei uchifanira kusarudza laser?
Chii chakasiyana pakati peLaser neIPL?
IPL inomiririra 'intense pulsed light' uye ine mamwe marudzi akasiyana akadai seSIPL, VPL, SPL, OPT, SHR ayo ese ari tekinoroji imwe chete. Michina yeIPL haisi lasers nekuti haina wavelength imwe chete. Michina yeIPL inogadzira bandwidth yakakura yewavelength inogona kusvika kudzika kwakasiyana kwenyama yeganda, inotorwa nezvinangwa zvakasiyana zvinosanganisira melanin, hemoglobin, mvura. Saka inogona kupisa nyama dzese dzakapoteredza kusvika pamhedzisiro yakawanda senge kubvisa bvudzi & kugadzirisa ganda, kubvisa mitsipa yeropa, kurapwa kwemapundu. Asi kurapwa nekunzwa kurwadziwa nekuda kwesimba rayo guru rechiedza chebroad spectrum, njodzi yekutsva kweganda ichave yakakwira kupfuura semiconductor diode lasers.
Muchina weIPL unoshandisa rambi re xenon riri mukati memubato unoburitsa chiedza, pane kristalo resafire kana quartz pamberi peganda, rinotamisa simba rechiedza uye rinoita kuti ganda ritonhore.
(mwenje wega wega uchava nechinhu chimwe chete chinoburitsa mapurose akawanda), rambi rexenon (hunhu hweGerman hunosvika mapurose 500000) hupenyu huchava hwakaderera kakawanda pane laser bar ye diode laser.
(ma "marco-channel" kana "micro-channel general" kubva pamamiriyoni maviri kusvika makumi maviri). Saka ma "laser" ekubvisa bvudzi (semuenzaniso Alexandrite, Diode, uye ND:Yag) anowanzova nehupenyu hwakareba uye kunzwa kwakasununguka pakurapa bvudzi risingadiwe. Ma "laser" aya anoshandiswa zvakanyanya munzvimbo yekubvisa bvudzi yehunyanzvi.
