Ukwelashwa kokukhanya okubomvu: kuyini, izinzuzo kanye nezingozi zesikhumba

Uma kukhulunywa ngokuthuthukisa izixazululo zokunakekelwa kwesikhumba, kunabadlali abaningana ababalulekile: odokotela besikhumba, onjiniyela bezokwelapha, ochwepheshe bezobuhle kanye… I-NASA? Yebo, emuva ekuqaleni kwawo-1990, i-ejensi yasemkhathini edumile (ngokungahlosile) yasungula uhlelo lokunakekelwa kwesikhumba oludumile.
Ekuqaleni kwaklanywa ukukhuthaza ukukhula kwezitshalo emkhathini, ososayensi bathola ngokushesha ukuthi ukwelashwa kokukhanya okubomvu (RLT) kungasiza futhi ekwelapheni amanxeba kwabashayeli bezindiza futhi kunciphise ukulahlekelwa kwamathambo; Umhlaba wobuhle usuqaphele.
I-RLT isetshenziswa kakhulu futhi ikhulunywa ngayo manje ngenxa yamandla ayo okuthuthukisa ukubukeka kwesikhumba njengemigqa emincane, imibimbi kanye nezibazi zama-acne.
Nakuba izinga eliphelele lokusebenza kwayo lisaphikiswana, kunocwaningo oluningi kanye nobufakazi obungacacile bokuthi, uma isetshenziswa kahle, i-RLT ingaba yisisombululo sangempela sokunakekelwa kwesikhumba. Ngakho-ke ake siqalise leli qembu lokunakekelwa kwesikhumba futhi sithole okwengeziwe.
Ukwelashwa nge-Light Emitting Diode (LED) kubhekisela emkhuba wokusebenzisa amaza ahlukene okukhanya ukwelapha izingqimba zangaphandle zesikhumba.
Ama-LED afika ngemibala ehlukene, ngalinye linobude be-wavelength obuhlukile. Ukukhanya okubomvu kungenye yezindlela ochwepheshe abazisebenzisa kakhulu ukukhuthaza ukukhiqizwa kwe-collagen, ukunciphisa ukuvuvukala, nokuthuthukisa ukujikeleza kwegazi.
“I-RLT ukusetshenziswa kwamandla okukhanya kobude obuthile besikhathi ezicutshini ukuze kufezwe umphumela wokwelapha,” kuchaza uDkt. Rekha Taylor, udokotela osungula i-Clinical for Health and Aesthetics. “La mandla asetshenziselwa ukukhulisa ukusebenza kwamaseli futhi angalethwa nge-laser ebandayo noma amadivayisi e-LED.”
Nakuba indlela esebenza ngayo ingacaci ngokuphelele, kucatshangwa ukuthi lapho ukukhanya kwe-RTL kushaya ubuso, kudonswa yi-mitochondria, izinto eziphilayo ezibalulekile emaseli ethu esikhumba ezibangela ukuphula izakhamzimba nokuziguqula zibe amandla.
“Cabanga ngakho njengendlela enhle yokuthi izitshalo zimunce ukukhanya kwelanga ukuze kusheshiswe i-photosynthesis futhi kukhuthazwe ukukhula kwezicubu,” kusho uTaylor. “Amangqamuzana abantu angamunca amaza okukhanya ukuze akhuthaze ukukhiqizwa kwe-collagen ne-elastin.”
Njengoba kushiwo ngaphambili, i-RLT isetshenziswa kakhulu ukuthuthukisa ukubukeka kwesikhumba, ikakhulukazi ngokwandisa ukukhiqizwa kwe-collagen, okwehla ngokwemvelo ngokuguga. Nakuba ucwaningo lusaqhubeka, imiphumela ibukeka ithembisa.
Ucwaningo lwaseJalimane lubonise ukuthuthuka ekuvuseleleni isikhumba, ukushelela kanye nobuningi be-collagen ezigulini ze-RLT ngemva kwamasonto ayi-15 ezikhathini ezingama-30; kuyilapho kwenziwa ucwaningo oluncane lwase-US lwe-RRT esikhumbeni esonakele elangeni amasonto ama-5. Ngemva kwezikhathi eziyi-9, imicu ye-collagen yaba mikhulu, okwaholela ekubukekeni okuthambile, okubushelelezi, nokuqinile.
Ngaphezu kwalokho, izifundo zikhombisile ukuthi ukuthatha i-RLT kabili ngesonto izinyanga ezimbili kunciphisa kakhulu ukubonakala kwezibazi zokusha; izifundo zokuqala zikhombisile ukuthi ukwelashwa kusebenza kahle ekwelapheni induna, i-psoriasis kanye ne-vitiligo.
Uma kukhona ongakuqondanga kulesi sihloko, ukuthi i-RLT ayilona ikhambi elisheshayo. I-Tailor itusa ukwelashwa okungu-2 kuya ku-3 ngesonto okungenani amasonto ama-4 ukuze ubone imiphumela.
Izindaba ezinhle ukuthi asikho isizathu sokwesaba noma sokwesaba ukuthola i-RLT. Ukukhanya okubomvu kukhishwa yithuluzi elifana nesibani noma imaski, futhi kuwela kancane ebusweni bakho - awuzizwa lutho nhlobo. “Ukwelashwa akubuhlungu, umuzwa ofudumele nje,” kusho uTaylor.
Nakuba izindleko ziyahlukahluka kuye ngomtholampilo, iseshini yemizuzu engama-30 izokubiza cishe u-$80. Landela izincomo izikhathi ezingu-2-3 ngesonto futhi uzothola ibhili elikhulu ngokushesha. Futhi, ngeshwa, lokhu akunakufunwa yinkampani yomshuwalense.
UTaylor uthi i-RLT iyindlela ehlukile engenabo ubuthi, engangenisi izidakamizwa kanye nokwelashwa okunamandla okufakwe endaweni yokwelashwa. Ngaphezu kwalokho, ayinayo imisebe ye-ultraviolet eyingozi, futhi izivivinyo zemitholampilo azizange ziveze noma yimiphi imiphumela emibi.
Kuze kube manje, kuhle kakhulu. Kodwa-ke, sincoma ukuthi uvakashele uchwepheshe wezokwelapha we-RLT oqeqeshiwe noqeqeshiwe, njengoba ukwelashwa okungafanele kusho ukuthi isikhumba sakho singase singatholi imvamisa efanele ukuze sisebenze kahle futhi, ezimweni ezingavamile, kungabangela ukusha. Bazoqinisekisa nokuthi amehlo akho avikelwe kahle.
Ungonga imali ethile futhi uthenge iyunithi yasekhaya ye-RLT. Nakuba ngokuvamile ziphephile ukuzisebenzisa, amaza azo aphansi asho ukuthi anamandla amancane. “Ngihlala ngincoma ukubona uchwepheshe ongakweluleka ngohlelo lokwelashwa oluphelele kanye ne-RLT,” kusho uTaylor.

Nakuba izinkinga zesikhumba ziyiyona nto eyinhloko ebangela i-RLT, amanye amalungu omphakathi wesayensi ajabule ngokuthi kungenzeka yini ukwelapha ezinye izifo. Kutholakale izifundo eziningana ezithembisayo:
I-inthanethi igcwele izimangalo ngalokho ukwelashwa kwe-RTL okungakufeza. Kodwa-ke, abukho ubufakazi obuqinile besayensi obusekela ukusetshenziswa kwayo uma kukhulunywa ngezinkinga ezilandelayo:
Uma uthanda ukuzama izindlela ezintsha zokunakekelwa kwesikhumba, unemali yokukhokha, futhi unesikhathi sokubhalisela ukwelashwa kwamasonto onke, asikho isizathu sokungazami i-RLT. Ungazithembi ngoba isikhumba somuntu wonke sihlukile futhi imiphumela izohluka.
Futhi, ukunciphisa isikhathi sakho elangeni eliqondile nokusebenzisa umuthi wokuvikela ilanga kuseyindlela ephumelela kakhulu yokunciphisa izimpawu zokuguga, ngakho-ke ungenzi iphutha lokucabanga ukuthi ungenza i-RLT bese uzama ukulungisa umonakalo.
I-Retinol ingenye yezithako ezinhle kakhulu emikhiqizweni yokunakekelwa kwesikhumba. Isebenza kahle ekunciphiseni yonke into kusukela emibimbi kanye nemigqa emincane kuya kokungalingani…
Ungaludala kanjani uhlelo lokunakekelwa kwesikhumba lomuntu ngamunye? Vele, ukwazi uhlobo lwesikhumba sakho nokuthi yiziphi izithako ezifanele kakhulu kuso. Sixoxisane nabaphezulu…
Isikhumba esiphelelwe amanzi emzimbeni asinawo amanzi futhi singaba buhlungu futhi sibe buthuntu. Cishe ungabuyisela isikhumba esiqinile ngokwenza izinguquko ezilula endleleni yakho yansuku zonke.
Izinwele ezimpunga eziseminyakeni yakho yo-20 noma yo-30? Uma usudayile izinwele zakho, nansi indlela yokuqedela ushintsho olumpunga nokuthi ungazilungisa kanjani
Uma ukunakekelwa kwesikhumba sakho kungasebenzi njengoba ilebula ithembisa, kungase kube yisikhathi sokuhlola ukuthi ngabe wenza noma yiliphi lala maphutha ngengozi.
Amabala okuguga ngokuvamile awayona ingozi futhi awadingi ukunakekelwa kwezokwelapha. Kodwa kunezindlela zasekhaya nezasehhovisi zokwelapha amabala okuguga ezikhanyisa futhi zikhanyise…
Izinyawo ze-Crow zingaba yinto ecasulayo. Nakuba abantu abaningi befunda ukuphila nemibimbi, abanye bazama ukuyilungisa. Yilokho kuphela.
Abantu abaningi abaseminyakeni yabo yama-20 nama-30 basebenzisa i-Botox ukuvimbela ukuguga nokugcina isikhumba sabo sisha futhi sisesisha.
