I ka makahiki 1998, ua ʻāpono ka FDA i ka hoʻohana ʻana i ka huaʻōlelo no kekahi mau mea hana o nā lasers wehe lauoho a me nā lako kukui pulsed. ʻAʻole manaʻo ka wehe lauoho mau loa i ka hoʻopau ʻana i nā lauoho āpau ma nā wahi mālama. ʻO ka hōʻemi lōʻihi a paʻa i ka nui o nā lauoho e ulu hou ana ma hope o kahi ʻano mālama.
Ke ʻike ʻoe i ke ʻano o ka lauoho a me ke kahua ulu a laila he aha ka laser therapy a pehea e hana ai?
Hoʻopuka nā lasers i hoʻolālā ʻia no ka hōʻemi lauoho mau loa i nā nalu o ke kukui i omo ʻia e ka melanin i loko o ka follicle lauoho (dermal papilla, matrix cells, melanocytes). Inā ʻoi aku ka māmā o ka ʻili a puni ma mua o ke kala o ka lauoho, ʻoi aku ka nui o ka ikehu laser e kau ʻia ma ke koʻokoʻo lauoho (selective photothermalysis), e luku pono ana iā ia me ka ʻole o ka hoʻopilikia ʻana i ka ʻili. Ke luku ʻia ka follicle lauoho, e hāʻule mālie ka lauoho, a laila e huli ka hana ulu lauoho i koe i ke kahua anagen, akā e lilo i lahilahi loa a palupalu ma muli o ka nele o ke kākoʻo meaʻai i ke olakino o ka ulu lauoho.
ʻO wai ka ʻenehana kūpono loa no ka wehe ʻana i ka lauoho?
ʻO ka epilation kemika kuʻuna, ka epilation mechanical a i ʻole ka epilation ʻumi me ka tweezer e ʻoki ana i ka lauoho ma ka epidermis e hoʻolilo i ka ʻili i laumania akā ʻaʻohe hopena i ka follicle lauoho, ʻo ia ke kumu e ulu koke ai ka lauoho, ʻoi aku ka ikaika ma mua o ka wā ma mua ma muli o ka hoʻoulu ʻana i ka lauoho hou aʻe i ke kahua anagen. Eia kekahi, hiki i kēia mau ʻano kuʻuna ke hōʻeha i ka ʻili, ke kahe koko, ka ʻike ʻili a me nā pilikia ʻē aʻe. E nīnau paha ʻoe ua lawe like ka IPL a me ka laser i ke kumumanaʻo lapaʻau like, no ke aha e koho ai i ka laser?
He aha ka ʻokoʻa ma waena o ka laser a me ka IPL?
ʻO IPL ke kū nei no ka 'intense pulsed light' a he mau ʻano like ʻole e like me SIPL, VPL, SPL, OPT, SHR ʻo ia hoʻi nā ʻenehana like. ʻAʻole nā mīkini IPL he lasers no ka mea ʻaʻole ia he nalu hoʻokahi. Hoʻopuka nā mīkini IPL i kahi bandwidth ākea o ka nalu e hiki ai ke hōʻea i nā hohonu like ʻole o ka ʻiʻo ʻili, e omo ʻia e nā pahuhopu like ʻole me ka melanin, hemoglobin, wai. No laila hiki ke hoʻomehana i nā ʻiʻo a puni a hiki i nā hopena multifuctional e like me ka wehe ʻana i ka lauoho a me ka hoʻoulu hou ʻana i ka ʻili, ka wehe ʻana i nā veins vascular, ka mālama ʻana i ka acne. Akā ʻo ka mālama ʻana me ka tingle a i ka ʻeha ma muli o kona ikehu kukui ākea ākea, ʻoi aku ka kiʻekiʻe o ka pilikia o ka puhi ʻana o ka ʻili ma mua o nā lasers semiconductor diode.
Hoʻohana ka mīkini IPL maʻamau i ke kukui xenon i loko o ka ʻāpana lima e hoʻopuka i ke kukui, aia kahi kristal sapphire a quartz paha ma ke alo e hoʻopā i ka ʻili e hoʻoili i ka ikehu kukui a hana i ka hoʻoluʻu e pale i ka ʻili.
(ʻo kēlā me kēia kukui e hoʻokahi puka e komo pū me nā pulses he nui), ʻo ke kukui xenon (ʻano Kelemania ma kahi o 500000 pulses) e emi ana ke ola ma mua o ka laser bar diode laser.
ʻano (marco-channel a i ʻole micro-channel laulā mai 2 a 20 miliona). No laila, ʻoi aku ka lōʻihi o ke ola o nā lasers wehe lauoho (ʻo ia hoʻi ʻo Alexandrite, Diode, a me ND: Yag types) a ʻoi aku ka ʻoluʻolu no ka mālama ʻana i ka lauoho makemake ʻole ʻia. Hoʻohana kūikawā kēia mau lasers i ke kikowaena wehe lauoho ʻoihana.
