ArbutinYikhompawundi eyenzeka ngokwendalo efumaneka kwimithombo eyahlukeneyo yezityalo efana nebhereberry, icranberries, kunye namaqunube.Ifumene ingqwalaselo ebalulekileyo kwishishini le-skincare kunye ne-cosmetic ngenxa yokuba lunokuba mhlophe ulusu kunye neempawu ezikhanyayo.Umatshini osemva kweziphumo ezimhlophe ze-arbutin ujikeleze amandla ayo okuthintela umsebenzi we-enzyme ebizwa ngokuba yi-tyrosinase, edlala indima ebalulekileyo ekuvelisweni kwe-melanin-ibala elibangela ulusu, iinwele kunye nombala wamehlo.
Umbala wolusu umiselwa ngumthamo kunye nokuhanjiswa kwe-melanin eveliswa yi-melanocytes, iiseli ezikhethekileyo kwi-epidermal layer.I-Tyrosinase yi-enzyme ephambili kwi-melanin synthesis pathway, eyenza ukuguqulwa kwe-amino acid tyrosine ibe yi-melanin precursors, ekugqibeleni ikhokelela ekwenziweni kwe-melanin pigments.I-Arbutin yenza isiphumo sayo sobumhlophe ngokuyintloko ngothintelo lokhuphiswano lomsebenzi we-tyrosinase.
I-Arbutin iqulethe ibhondi ye-glycoside, elunxibelelwano lweekhemikhali phakathi kwe-molecule ye-glucose kunye ne-hydroquinone molecule.IHydroquinone yikhompawundi eyaziwayo eneempawu ezikhanyisa ulusu, kodwa inokuba rhabaxa eluswini kwaye inyanyaniswa neziphumo ebezingalindelekanga.I-Arbutin, kwelinye icala, isebenza njengenye indlela ethambileyo kwi-hydroquinone ngelixa ibonelela ngothintelo olusebenzayo lwemveliso ye-melanin.
Xa i-arbutin isetyenziswa eluswini, iyafunxwa kwaye ifakwe kwi-hydroquinone ngeenkqubo ze-enzymatic.Le hydroquinone ngoko ngokukhuphisanayo inqanda isenzo se-tyrosinase ngokuhlala kwindawo yayo esebenzayo.Ngenxa yoko, iimolekyuli ze-tyrosine azikwazi ukuguqulwa ngokufanelekileyo zibe yi-melanin precursors, ekhokelela ekunciphiseni imveliso ye-melanin.Oku ekugqibeleni kukhokelela ekuncipheni ngokuthe ngcembe kumbala wolusu, okukhokelela ekubeni ulusu lube khaphukhaphu nangakumbi.
Kubalulekile ukuqaphela okoukwenziwa mhlophe kwe-arbutiniziphumo azikho kwangoko.Ukuguqulwa kolusu kuthatha malunga nenyanga, ngoko ke ukusetyenziswa okungaguquguqukiyo kunye nexesha elide kweemveliso ezine-arbutin kuyimfuneko ukujonga utshintsho olubonakalayo kwi-pigmentation yesikhumba.Ukongeza, indlela yokusebenza ye-arbutin isebenza ngakumbi ekujonganeni nemiba enxulumene ne-hyperpigmentation, efana namachaphaza eminyaka, amabala elanga, kunye ne-melasma, kunokuguqula umbala wolusu wendalo.
Iprofayile yokhuseleko ye-Arbutin inyamezeleke ngcono kunezinye iiarhente ezikhanyisa ulusu, nto leyo eyenza ibe lukhetho oludumileyo kubantu abafuna ukulungisa ithoni yesikhumba engalinganiyo.Nangona kunjalo, ukusabela komntu ngamnye kunokwahluka, kwaye kuyacetyiswa ukuba wenze uvavanyo lwe-patch ngaphambi kokufaka iimveliso ezintsha ze-skincare kwindlela yakho.
Ukuqukumbela, indlela yokwenza mhlophe ulusu lwe-arbutin ixhomekeke kumandla ayo okuthintela umsebenzi we-tyrosinase, ekhokelela ekunciphiseni imveliso ye-melanin.Uthintelo lwayo lokukhuphisana kwe-tyrosinase, olukhokelela ekucuthekeni kwe-melanin synthesis, kuyenza ibe sisithako esinomtsalane kwiimveliso ze-skincare ezijolise kwi-hyperpigmentation kunye nethoni yesikhumba engalinganiyo.Njengaso nasiphi na isithako sokhathalelo lwesikhumba, kuyacetyiswa ukuba udibane nogqirha wesikhumba phambi kokuba ungenise iimveliso ezintsha kwindlela yakho yesiqhelo, ngakumbi ukuba unenkxalabo ethile yolusu okanye iimeko.
