Pakati pa matekinoloje ambiri ochotsa tsitsi, ndi755nm Alexandrite Laserwakhala akutamandidwa ngati "golide muyezo" m'munda akatswiri. Komabe, kwa ogula omwe akufuna njira zochotsera tsitsi, funso lofunikira likadalipo: Kodi ndi lothandizadi? Kodi ndi nthabwala chabe zamalonda, kapena umisiri wotsimikiziridwa mwasayansi ndi wodalirika? Nkhaniyi ifotokoza zaukadaulo wapamwamba wa laser kuti akupatseni yankho mwadongosolo ku funsoli.
Chifukwa chiyani ma 755nm Alexandrite lasers amatha kuchotsa tsitsi ndendende?
Kusankhiratu kutalika kwa mafunde: Ma laser a 755nm amagwera pafupi ndi-mawonekedwe a infrared. Kutalika kwa mafunde awa ndi amodzi mwa "nsonga zabwino kwambiri zoyamwa" za melanin. Melanin pakhungu (kaya ndi mawanga, madontho adzuwa mu epidermis, kapena melanin m'mitsempha yatsitsi) amayamwa kutalika kwa mafundewa ndikuchita bwino kwambiri, pomwe minofu yozungulira imayamwa pang'ono. Izi zikutanthauza kuti pamene 755nm laser pulse imagwira pakhungu, mphamvuyo "mwadyera" imatengedwa ndi melanin chandamale ndikusandulika kutentha, nthawi yomweyo imatulutsa kutentha kwambiri. Izi zimawononga bwino ma granules a pigment kapena ma follicle atsitsi, ndikuchepetsa kuwonongeka kwa khungu lozungulira.
Poyerekeza ndi mafunde amfupi a lasers (monga 532nm laser), 755nm lasers amalowa mkati mwa khungu, kufika ku dermis, motero amalondolera bwino ma follicles atsitsi, ma pigment granules, ndi zolinga zina.
Poyerekeza ndi kutalika kwa mafunde a laser (monga1064nm Nd: YAG lasers), kuchuluka kwa hemoglobini kumakhala kochepa, kumachepetsa chiopsezo cha magazi a subcutaneous ndi purpura panthawi ya chithandizo, motero kumapangitsa chitetezo.
Mosiyana ndi njira zachikhalidwe zomwe zimangochotsa tsitsi kwakanthawi (monga kumeta ndi kumeta), ma lasers amayang'ana mwachindunji kapangidwe kake kakulidwe ka tsitsi, kuwonongeratu ntchito yake ndikuchepetsa tsitsi kosatha.
Poyerekeza ndi electrolysis, chithandizo cha laser chimakwirira dera lalikulu pa liwiro la kuwala, kupangitsa kuti ikhale yogwira mtima kwambiri, ndipo luso laogwira ntchito ndilofanana.
Bungwe la US Food and Drug Administration (FDA) ndi mabungwe angapo akuluakulu olamulira zida zamankhwala padziko lonse lapansi avomereza "kuchepetsa tsitsi kosatha." Izi zikutanthauza kuti chitetezo ndi mphamvu zake zimakwaniritsa mfundo zokhwima zachipatala-zachipatala.
755nm Alexandrite Laser vs 808nm Diode Laser
Kusinthasintha kwa Tsitsi ndi Khungu:
Ma lasers a 755nm amapereka zotsatira zabwino kwambiri zochotsera tsitsi pakhungu lopepuka la tsitsi lakuda{1}}nm imakhala yosinthasintha, imaphimba bwino komanso imaphimba khungu kuchokera kukuwala kupita kukatikati-yakuda, ndipo imasintha ndi makulidwe a tsitsi.
Chithandizo Chachangu:
Laser ya 755nm ili ndi chiwopsezo chachikulu kwambiri cha mayamwidwe a melanin pakati pa ma laser onse ochotsa tsitsi. Izi zikutanthauza kuti ali ndi "chokopa" champhamvu kwambiri komanso kutembenuka kwamphamvu kwa melanin mu follicle ya tsitsi.
Kwa tsitsi lakuda, lakuda, mphamvu zomwe zimatengedwa ndi follicle ya tsitsi zimakhazikika kwambiri, ndipo kuwonongeka kwa tsitsi komwe kumayambitsidwa ndi 755nm laser kumakhala kokwanira, komwe kumawoneka kuti kumabweretsa zotsatira zazikulu pamankhwala aliwonse, zomwe zimafuna magawo ochepa.
Mafunde a 808nm ndiatali pang'ono, olowera mozama kuposa laser 755nm. Mayamwidwe ake a melanin ndiotsika pang'ono kuposa 755nm, koma akadali abwino kwambiri, ndipo amayamwa hemoglobin yocheperako.
Kodi ndingasankhe bwanji njira yochotsera tsitsi la laser yomwe imagwirizana ndi zosowa zanga?
Sankhani 755nm alexandrite laser:
- Khungu la mtundu I-III: Umu ndi momwe zilili bwino755nm laserimapereka zotsatira zabwino kwambiri, zopatsa odwala zotsatira zachangu komanso zomveka bwino.
- Kufuna magawo ochepa a chithandizo momwe angathere: Pamikhalidwe yabwino, kuchepetsa tsitsi kokhutiritsa kumatha kutheka ndi magawo ochepa.
- Kuyika patsogolo kuchita bwino: Kukula kwake kwakukulu kwa malo ndi njira yotsetsereka imapulumutsa nthawi yayikulu.
Sankhani 808nm diode laser:
- Khungu la mtundu III-IV: Laza ya 808nm ndiyothandiza kwambiri pakhungu ili ndipo imapereka chitetezo chapamwamba.
- Tsitsi lakuda: Ndilabwino kwambiri-kumanenepa, tsitsi lakuda.
- Khungu lomva kapena kumva kupweteka kwambiri: Kulowa kwake mozama komanso kutulutsa mphamvu kokhazikika, kuphatikiza ndi kuziziritsa kwapamwamba, kumapangitsa kuti munthu azitha kulandira chithandizo mofatsa.
- Mitundu yatsitsi yovuta: Monga njira "yoyenera" kwambiri, laser 808nm imapereka kulolerana kwakukulu pakhungu ndi mawonekedwe atsitsi.
Ndani ali woyenera kwambiri chithandizo cha 755nm Alexandrite Laser?
Makhalidwe abwino opangira chithandizo chochotsa tsitsi la laser ndi "khungu lopepuka, tsitsi lakuda". Chifukwa melanin ndiye chandamale cha kuyamwa mphamvu, tsitsi likakhala lakuda komanso lalitali, limatenga mphamvu zambiri, komanso zotsatira zake zimakhala zabwino. Mosiyana ndi zimenezi, tsitsi loyera, imvi, blonde, kapena lofiira lilibe melanin ndipo limatenga mphamvu zochepa kwambiri, zomwe zimapangitsa kuti zisagwire ntchito.
Panthawi imodzimodziyo, khungu la khungu silingakhale lakuda kwambiri (Fitzpatrick mtundu wa IV ndi pamwambapa zimafuna kusamala kwambiri), monga melanin mu epidermis idzapikisana ndi tsitsi kuti itenge mphamvu, kuonjezera chiopsezo cha kutentha kwa epidermal, hyperpigmentation, kapena kutayika tsitsi. Ngakhale zida zamakono zili ndi machitidwe ozizira kuti ateteze epidermis, zofooka za khungu zimakhalabe zofunika kuziganizira.
Ndi magawo angati amankhwala omwe amafunikira kuti mukwaniritse zotsatira zomwe mukufuna?
Kuchiza kumakhala kothandiza kwambiri tsitsi likamakula, lokhala ndi ma follicles osalimba komanso melanin yambiri. Komabe, tsitsi laumunthu limadutsa mosiyanasiyana (anagen, catagen, ndi telogen phases), ndipo chithandizo chimodzi chimatha kuphimba gawo la tsitsi mu gawo la kukula. Choncho, mankhwala angapo (nthawi zambiri amakhala motalikirana kwa miyezi 1-2) ndikofunikira kuti "agwire" magawo onse atsitsi. Ili ndi gawo lofunikira mwasayansi kuti mupeze zotsatira zochulukira komanso zokhalitsa, osati zomwe opanga amawonjezera mwadala kuchuluka kwamankhwala.
Ma Genetics ndi endocrine amakhudza kwambiri mawonekedwe a tsitsi. Kwa tsitsi lolimbikitsidwa ndi androgens, chithandizo cha laser chimatha kuchotsa bwino tsitsi lomwe lilipo. Komabe, ngati kuchuluka kwa timadzi ta m'kati sikukhala kodziwika bwino, kungayambitse kuyambika kwa timitsempha tatsitsi tatsopano tating'onoting'ono, zomwe zimafuna chithandizo chamankhwala chotsatira. Choncho, chithandizo cha laser chimodzi sichikwanira kuchepetsa tsitsi losafunikira.
