Iphaneli Yokwelapha Ngokukhanya Kwe-LED Isebenza Kanjani Ezinkingeni Ezihlukene Zesikhumba?

Siyakwamukela ekubukeni okucacile nokukhanyayo kokuthi amaphaneli okwelapha ngokukhanya kwe-LED asebenzisana kanjani nezinkinga zesikhumba zazo zonke izinhlobo. Uma wake wazibuza ukuthi kungani kusetshenziswa izibani ezinemibala ehlukene kumadivayisi okunakekela isikhumba, kwenzekani ngempela ngaphansi kwesikhumba lapho iphaneli ivuliwe, noma ukuthi unganquma kanjani ukuthi idivayisi yasekhaya noma ukwelashwa kochwepheshe kulungile yini kuwe, lesi sihloko sizokuqondisa ngesayensi namaqiniso angokoqobo ngendlela elula ukuyilandela futhi ewusizo. Hlala ubukele ukuze uthole ukuthi ubude be-wavelength ethile bubhekana kanjani nezinduna, ukuguga, ukuvuvukala, ukuguquka kwebala, nokuningi - nokuthi yini ongayilindela ngokusetshenziswa njalo.

Abantu abaningi bathola umqondo wokwelapha izinkinga zesikhumba ngokukhanya okumangalisayo noma ngisho nangesikhathi esizayo. Kodwa ukwelashwa kwe-LED kuhlanganisa amashumi eminyaka ocwaningo lwe-photobiology nobuchwepheshe obufinyelelekayo babathengi. Kungakhathaliseki ukuthi ucabanga ngephaneli encane ongayisebenzisa ekhaya noma ubheka izinketho zasemtholampilo, ukufunda ukuthi amaza okukhanya ahlukene asebenza kanjani nokuthi ahumushela kanjani ezinzuzweni zesikhumba ezilinganisekayo kungakusiza wenze izinqumo eziqinisekile kanye nokulindela okungokoqobo.

Ukuqonda isayensi: indlela ukukhanya kwe-LED okuxhumana ngayo namaseli esikhumba

Ukwelashwa kokukhanya kwe-LED kusebenza ngesimiso se-photobiomodulation, okusho ukusebenzisa ubude besikhathi bokukhanya obuthile ukushintsha ukuziphatha kweseli. Ngokungafani nama-laser athembele emandleni aphezulu ukuqeda noma ukusika izicubu, amaphaneli e-LED aletha ukukhanya okuphansi ezindaweni ezibanzi futhi asebenza ngokuvuselela izinqubo zebhayoloji ezingeni leseli. Lapho ama-photon avela ku-LED yobude besikhathi obuthile engena esikhumbeni, amuncwa ama-chromophores - ama-molecule angaphakathi kwamaseli asebenza njenge-antenna encane yokukhanya. Enye yama-chromophores abaluleke kakhulu kumaseli esikhumba yi-cytochrome c oxidase, i-enzyme ku-mitochondria ehilelekile ekuphefumuleni kwamaseli. Ukumuncwa kokukhanya okubomvu nokuseduze kwe-infrared kungandisa umsebenzi we-cytochrome c oxidase, okwandisa ukukhiqizwa kwe-ATP, imali yamandla eyinhloko yeseli. I-ATP eyengeziwe isiza amaseli ukwenza umsebenzi wokulungisa nokuvuselela ngempumelelo, okukhuthaza ama-fibroblast ukukhiqiza i-collagen ne-elastin, ukuthuthukisa ukuguquka kwamaseli, nokusekela ukulungiswa kwezicubu.

Ngale kokukhiqizwa kwe-ATP, i-photobiomodulation ithonya izinhlobo ze-oxygen ezisabelayo (i-ROS) kanye nezindlela ze-nitric oxide (NO). Ngamanani alawulwayo, i-ROS isebenza njengama-molecule okubonisa angakhulisa izindlela zokuzivikela kanye nezinhlelo zokulungisa. Ukuvezwa kokukhanya kungakhuphula amazinga e-ROS okwesikhashana, okubangela izinguquko zokubonakaliswa kwezakhi zofuzo ezikhuthaza ukuqina kwamaseli. Ngesikhathi esifanayo, ukukhishwa kwe-nitric oxide kungathuthukisa i-microcirculation ngokukhulisa imithambo yegazi emincane, kusekele ukulethwa kwezakhamzimba kanye nokususwa kwemfucuza esikhumbeni. Le miphumela yemithambo yegazi iyingxenye yokuthi kungani amaza athile anganciphisa ukubomvu futhi asheshise ukuphulukiswa.

Ama-wavelength ahlukene angena ekujuleni okuhlukahlukene. Ukukhanya okuluhlaza okwesibhakabhaka, kuma-wavelength aphansi azungeze u-415 nm, kumuncwa kakhulu ku-epidermis engaphezulu futhi kuhlose izakhiwo ezingaphezulu njengamagciwane kanye nezindlala ze-sebaceous ezisebenzayo kakhulu. Ukukhanya okubomvu (cishe u-630-660 nm) kanye ne-near-infrared (cishe u-800-850 nm) kungena ngokujulile ku-dermis, kufinyelele kuma-fibroblast, emithanjeni yegazi, kanye namaseli omzimba ajulile. Ngenxa yokuthi amaphaneli e-LED ngokuvamile asebenzisa inhlanganisela yala ma-wavelength, angakhiqiza imiphumela ehlukene: isenzo sokulwa namagciwane ebusweni esivela ekukhanyeni okuluhlaza okwesibhakabhaka kuhlanganiswe nokulungiswa okujulile kanye nesenzo sokulwa nokuvuvukala esivela kubomvu kanye ne-near-infrared. Okubalulekile, i-photobiomodulation ayishisi uma isetshenziswa ngaphakathi kwebanga lokwelapha; ayishisi izicubu ezifana nama-sauna e-infrared noma ama-laser ablative, okufaka isandla ekuphepheni kwayo.

Nakuba imiphumela yamakhemikhali ithembisa, impendulo incike kumthamo kanye nesikhathi. Ukukhanya okuncane kakhulu kungase kungabi namphumela; okuningi kakhulu kungabangela ukuvinjelwa kwe-photoinhibition, lapho izinqubo ezizuzisayo zincipha noma zincipha. Umqondo wempendulo yomthamo we-biphasic usho ukuthi ukwelashwa okuphumelelayo kudinga ibhalansi efanele yobude be-wavelength, ukukhanya (amandla ngendawo ngayinye), kanye nesikhathi sokuchayeka. Ngaphezu kwalokho, izici ngazinye ezifana nombala wesikhumba, ukujiya, kanye nezimo ezingaphansi kuzothinta indlela ukukhanya okumuncwa ngayo kanye nemiphumela ongayilindela. Lokhu kuxhumana okuhlanganisiwe phakathi kwe-physics, i-chemistry, kanye ne-biology yikho okwenza ukwelashwa kwe-LED kube okuguquguqukayo kodwa futhi kudinga indlela enolwazi yemiphumela emihle kakhulu.

Ukukhanya okubomvu nokucishe kube yi-infrared: ukubuyisela emuva izimpawu zokuguga nokuvuselela ukulungiswa

Ama-wavelength abomvu naseduze kwe-infrared avame ukudunyiswa njengomgogodla wezinqubo ze-LED zokulwa nokuguga ngenxa yamandla awo okuvuselela izingxenye ezinikeza amandla esikhumba kanye nokuguquguquka. Lawa ma-wavelength angena ngokujulile kunokukhanya okuluhlaza okwesibhakabhaka, afinyelele ku-dermis lapho kuhlala khona ama-fibroblast - amangqamuzana abhekene nokukhiqiza i-collagen ne-elastin -. Lapho lawa maseli ethola isignali yokukhanya efanele, andisa ukukhiqizwa kwamaprotheni esakhiwo, athuthukise ukujiya kwesikhumba futhi anciphise ukubonakala kwemigqa emincane nemibimbi. Ukwanda kwe-ATP kanye nokusebenza kwezindlela zezakhi zofuzo ezihlobene nokulungiswa kusiza amangqamuzana ukuthi akhiqize i-matrix eyengeziwe yangaphandle futhi athuthukise imetabolism yesifunda, engahumushela esikhumbeni esiqinile nesiqinile ngokuhamba kwesikhathi.

Nakuba kungeyona ikhambi elijwayelekile, ukwelashwa nge-LED kunikeza inketho emnene, esekelwe kwesayensi yokunciphisa ukuvuvukala nokusekela ukuzinza kwesikhumba isikhathi eside.

Ukushintshashintsha kombala kanye nethoni engalingani: indlela ukukhanya okuthinta ngayo i-melanin kanye nezindlela zokushintsha umbala

Ukushintsha umbala wesikhumba — okuhlanganisa ukuguquguquka kombala wesikhumba ngemva kokuvuvukala, i-melasma, kanye namabala elanga — kuletha inselele eyinkimbinkimbi ngoba kuhilela ukukhiqizwa kwe-melanin, ukudluliselwa kwe-melanosome kuma-keratinocyte, kanye nethonya lokuvuvukala lendawo elibangela ukwakheka kombala okweqile. Ukwelashwa kokukhanya kwe-LED akuyona into ebangela ukumhlopheza ngomqondo wendabuko, kodwa kungasiza ngokungaqondile ekuthuthukiseni ithoni yesikhumba ngezindlela eziningana. Okokuqala, imiphumela yokulwa nokuvuvukala yokukhanya okubomvu nokuseduze kwe-infrared inciphisa ingozi yokufakwa kombala okubangelwa ukuvuvukala. Ngemva kokulimala noma isilonda se-acne, ukuvuvukala kwendawo kuvame ukukhuthaza ama-melanocyte ukuthi akhiqize umbala ngokweqile; ngokuthulisa lokho kuvuvukala, ukwelashwa kwe-LED kunganciphisa izindawo ezimnyama zesikhathi esizayo ngemva kokuvuvukala.

Ngaphezu kwalokho, i-photobiomodulation isekela ukushintshashintsha kwesikhumba kanye nokulungiswa, okusiza ukususwa kancane kancane kwama-keratinocyte anombala futhi kusheleleze ithoni yesikhumba. Ngokukhuthaza ukuziphatha okunempilo kwe-keratinocyte kanye nokukhuthaza ukuvuselelwa kwamaseli alawulwayo, ukwelashwa kwe-LED kusiza enkambisweni yemvelo yokushabalala kombala othile ongaphezulu ngokuhamba kwesikhathi. Ukwelashwa kungase futhi kuguqule izindlela zokubonisa ezilawula umsebenzi we-melanocyte, yize lo mphumela uvame ukuba mncane futhi uhamba kancane uma uqhathaniswa nemithi yokususa ibala eqondiwe noma ukwelashwa nge-laser okuhloselwe ngqo i-melanin.

Ngokushintsha kombala okungapheli njenge-melasma, okuthonywa ama-hormone kanye nokuchayeka elangeni, ukwelashwa kwe-LED kukodwa akunakwenzeka ukuthi kuveze ukukhanya okukhulu. Kodwa-ke, kungaba isithasiselo esiwusizo ezintweni ezisetshenziswayo njengezindlela ze-hydroquinone, ama-retinoids, kanye nemikhuba yokuvikela ilanga. Imvelo ye-LED engavuvuki isho ukuthi ingahlanganiswa ngokuphephile nezindlela eziningi zokwelashwa, uma nje uhlelo lonke luqondiswa udokotela ukuze kugwenywe izindlela zokwelapha ezingqubuzanayo noma ukwanda kokuzwela kwe-photosensitivity ezivela kwezinye izithako.

Uma kuqhathaniswa i-LED namadivayisi afana nokukhanya okunamandla okushaywa (i-IPL) noma ama-laser, lokhu kokugcina kunikeza amandla agxilile aphula noma ashise i-melanin lapho kusetshenziswa amaza nama-fluences afanele. Lokhu kwelashwa kunganikeza ukwehla okusheshayo nokubonakalayo kombala kodwa kunengozi ephezulu yokuvuvukala ngemuva kwenqubo kanye nokwanda kombala okungenzeka kube khona, ikakhulukazi ezinhlotsheni zesikhumba ezimnyama. Ukwelashwa kwe-LED, njengoba kunamandla aphansi futhi kungaqedi, kunengozi encane futhi kungaba inketho ethambile yokugcinwa, ukuvimbela umbala omusha, kanye nokuthuthukisa ukufana kwesikhumba sonke uma kuhlanganiswa nokuvikelwa kwelanga nokunakekelwa kwangaphandle. Isineke nokusetshenziswa njalo kubalulekile; izinguquko ekufakweni kombala nge-LED zihamba kancane kancane, ngokuvamile zidinga izinyanga eziningana ukuze zibonakale.

Izinto okufanele uzicabangele: ukukhetha iphaneli, izinhlelo zokwelapha, ukuphepha, kanye nokuhlanganisa izindlela zokwelapha

Uma ukhetha iphaneli ye-LED futhi uhlela inqubo yokwelapha, izici eziningana ezisebenzayo zithinta ukusebenza kahle kanye nokuphepha. Ubude be-wavelength yikona okufanele kucatshangelwe kuqala: funa amadivayisi achaza ngokucacile ubude be-wavelength obuphezulu ababukhiphayo. Amaphaneli ahlanganisa ama-LED aluhlaza okwesibhakabhaka, abomvu, kanye nama-LED aseduze ne-infrared anikeza ukuguquguquka kokubhekana nezinkinga eziningi, kodwa kubalulekile ukuthi idivayisi inikeze ukukhanya okubalulekile emtholampilo. Ukukhanya — okuvame ukubikwa njenge-mW/cm² — kunquma ukuthi kungakanani amandla afinyelela esikhumbeni ngesikhathi ngasinye. Amadivayisi anokukhanya okuphansi kakhulu angadinga izikhathi ezinde futhi anganikeza imithamo yokwelapha enganele, kuyilapho amadivayisi anamandla kakhulu asetshenziswa ngendlela engafanele angaholela ekuvinjelweni kwe-photoinhibition noma izimpendulo ezingalindelekile. Abakhiqizi abathembekile bazonikeza isiqondiso ngamabanga anconyiwe kanye nobude besikhathi seseshini ukuze kufezwe ukulethwa kwamandla okuphumelelayo.

Ukuvama kweseshini kanye nobude besikhathi kuncike esimweni. Izinqubo eziningi ziqala ngeseshini ezivame kakhulu (isibonelo, izikhathi eziningana ngesonto) ukwakha amandla eseli, kulandelwe ishejuli yokulungisa. Ukuze kulwiswane nokuguga kanye nokulungiswa, imihlangano ejwayelekile yamasonto onke noma yamasonto amabili ngemuva kwesigaba sokuqala esinzima ingagcina intuthuko. Ngezinduna kanye nokuvuvukala, imihlangano yokuqala evame kakhulu ingafinyeza iziqephu ezisebenzayo. Gcina ukulindela okungokoqobo: izinzuzo eziningi zihamba kancane kancane futhi ziyahlangana, ngakho-ke ukuhambisana kubalulekile.

Izinto okufanele uzicabangele ngokuphepha zihlanganisa ukungavumelani nokusebenzisana. Abantu abasebenzisa imithi ethinta ukukhanya - ama-antibiotic athile, ama-retinoids, noma izithasiselo zamakhambi - kufanele baxhumane nodokotela wezempilo ngaphambi kokusebenzisa ukwelashwa kwe-LED ngoba isikhumba sabo singase sisabele ngokungalindelekile ekukhanyeni. Ukuvikelwa kwamehlo kuyalulekwa, ikakhulukazi ngokukhanya okuluhlaza okwesibhakabhaka, ukugwema ukukhanya okukhanyayo kanye nokungakhululeki okungenzeka kwe-retina. Ukwelashwa kwe-LED ngokuvamile kuphephile ngesikhathi sokukhulelwa, kodwa ukuhlola nodokotela wezempilo kuhlale kuyisinyathelo esihlakaniphile. Abasebenzisi abanezifo ezisebenzayo, amanxeba avulekile adinga ukunakekelwa kwezokwelapha, noma umlando wezinkinga ezithinta ukukhanya kufanele bathole imvume yezokwelapha.

Ukuhlanganisa i-LED nezinye izindlela zokwelapha kungakhulisa imiphumela uma kwenziwa ngokucabangela. Isibonelo, ukusebenzisa i-LED ngemuva kokusebenzisa i-microneedling kunganciphisa isikhathi sokungasebenzi futhi kusheshise ukuphulukiswa, kuyilapho ukuhlanganisa ukukhanya okuluhlaza okwesibhakabhaka nokubomvu kulungisa kokubili izici ezincane nezivuvukisayo ze-acne. Gwema ukusebenzisa izinqubo zokukhipha ukungcola okunamandla ngokushesha ngaphambi kokwelashwa kokukhanya ngaphandle kokuthi kuqondiswe udokotela. Ukusebenzisa i-LED ngokuvumelana nama-antioxidants angaphandle, ama-peptide, kanye nama-sunscreen kudala uhlelo oluphelele: i-photobiomodulation isekela ukulungiswa nokuqina, kuyilapho ama-topical ebhekana nezidingo kanye nokuvikelwa kwezinga eliphezulu.

Okokugcina, hlukanisa phakathi kwamadivayisi asetshenziswa ekhaya nezinhlelo zobungcweti. Amayunithi angaphakathi ehhovisi ngokuvamile makhulu, aletha ukukhanya okuphezulu, futhi aqhutshwa ngabasebenzi abaqeqeshwe abangakwazi ukwenza izinqubo ngokuvumelana nezidingo zomuntu ngamunye. Amadivayisi asekhaya anikeza ukulula kanye nekhono lokugcina uhlelo olujwayelekile kodwa avame ukungabi namandla anele; kubasebenzisi abaningi, ukusetshenziswa kwekhaya njalo kuveza izinzuzo ezinengqondo, kanti ngezinkinga ezijulile noma ezinzima kakhulu, indlela ehlanganisiwe - izikhathi zobungcweti ezihlanganiswe nokulungiswa kwekhaya - ivame ukuveza imiphumela emihle kakhulu.

Ngamafuphi, amaphaneli okwelapha ngokukhanya kwe-LED asebenza nge-photobiomodulation, evuselela ngokukhetha izindlela zamaseli ukunciphisa ukuvuvukala, ukulwa namagciwane, ukukhuthaza ukulungiswa, kanye nokuthonya ngobuqili ukukhiqizwa kombala namafutha. Ukukhetha ubude bamaza, umthamo, kanye nokuvumelana konke kuthinta imiphumela, futhi ukuguquguquka kwalolu hlobo lokwelapha kulwenza lube usizo kuzo zonke izinkinga zesikhumba. Ukuphepha ngokuvamile kuyathandeka, kodwa ukwenza indlela ivumelane nezidingo zomuntu ngamunye kanye nochwepheshe bokubonisana nezimo eziyinkimbinkimbi kuqinisekisa imiphumela engcono nehlala njalo.

Ukuze sifingqe, lesi sihloko sihlole isisekelo sebhayoloji sokwelashwa kwe-LED, ukuthi amaza okukhanya ahlukene abhekana kanjani nezinkinga ezithile zesikhumba, kanye nezinyathelo ezisebenzayo zokukhetha nokusebenzisa iphaneli ngempumelelo. Ukuqonda isayensi ngemuva kombala ngamunye wokukhanya kanye nokwelashwa okuhlanganisiwe kanye nemikhuba yokunakekelwa kwesikhumba enengqondo kuzokusiza ukufeza imiphumela ephephile nebikezelekayo. Kungakhathaliseki ukuthi uphishekela izikhathi zasehhovisi, utshala imali kuphaneli yasekhaya, noma uhlanganisa kokubili, indlela ecatshangelwe kahle nehambisanayo iyindlela ethembeke kakhulu eya esikhumbeni esicacile nesibukeka sinempilo.
