Ekuphishekeleni ukugqama kwesikhumba, i-arbutin, njengesithako semvelo esenza sibe mhlophe, ivusa uguquko lwesikhumba oluthule. Le nto esebenzayo ekhishwe emaqabunga ezithelo zebhere isiphenduke inkanyezi ekhanyayo emkhakheni wokunakekelwa kwesikhumba yesimanje ngenxa yezici zayo ezithambile, imiphumela ebalulekile yokwelapha, nokusebenza okubanzi.
1. Ukuqoshwa kwesayensi kweAlpha Arbutin
I-Arbutin iphuma ku-hydroquinone glucoside, etholakala kakhulu ezitshalweni ezifana ne-bear fruit, izihlahla zamapheya, nokolweni. Isakhiwo sayo samangqamuzana sakhiwe ngamaqembu e-glucose kanye ne-hydroquinone, futhi lesi sakhiwo esiyingqayizivele sisenza sikwazi ukuvimbela ngobumnene nangempumelelo ukukhiqizwa kwe-melanin. Emkhakheni wokunakekelwa kwesikhumba, i-alpha arbutin ithandwa kakhulu ngenxa yokuqina nokusebenza kwayo okuphezulu.
Indlela yokwenza mhlophe ye-arbutin ibonakala kakhulu ekuvinjweni komsebenzi we-tyrosinase. I-Tyrosinase iyi-enzyme eyinhloko ekuhlanganiseni kwe-melanin, futhi i-arbutin ivimbela ngokuncintisana ukuguqulwa kwe-dopa ibe yi-dopaquinone, ngaleyo ndlela yehlise ukukhiqizwa kwe-melanin. Uma iqhathaniswa ne-hydroquinone yendabuko, i-arbutin inomphumela omnene futhi ayibangeli ukucasuka noma imiphumela engemihle esikhumbeni.
Ngesikhathi senqubo ye-metabolic esikhumbeni, i-arbutin ingakhulula kancane i-hydroquinone, futhi le ndlela yokukhululwa elawulekayo iqinisekisa ukuqina nokuphepha komphumela wayo wokuba mhlophe. Ucwaningo luye lwabonisa ukuthi ngemva kokusebenzisa imikhiqizo ye-skincare equkethe i-arbutin engu-2% emavikini angu-8, indawo ye-pigmentation yesikhumba ingancishiswa ngo-30% -40%, futhi ngeke kube khona into emnyama.
2. Izinzuzo eziphelele ze-skincare
Umthelela obaluleke kakhulu we-arbutin ukuba mhlophe kwawo okuhle kakhulu kanye nekhono lokukhanyisa amabala. Idatha yomtholampilo ibonisa ukuthi ngemva kwamaviki angu-12 okusetshenziswa okuqhubekayo kwemikhiqizo ye-skincare equkethe i-arbutin, abasebenzisi abangu-89% babike ukuthuthuka okuphawulekayo kwethoni yesikhumba kanye nokwehliswa kwesilinganiso okungama-45% endaweni enemibala. Umphumela wayo wokuba mhlophe uqhathaniswe ne-hydroquinone, kodwa iphephile futhi ifanele ukusetshenziswa isikhathi eside.
Ngokuya ngezakhiwo ze-antioxidant, i-arbutin ikhombisa amandla aqinile wokulahla ama-radical mahhala. Ukuhlola kubonise ukuthi umsebenzi wayo we-antioxidant uphindwe izikhathi ezingu-1.5 kune-vitamin C, enganciphisa ngempumelelo ama-radicals mahhala e-UV futhi ivikele amangqamuzana esikhumba emonakalweni we-oxidative. Phakathi naleso sikhathi, i-arbutin nayo inezindawo zokulwa nokuvuvukala, ezingadambisa ububomvu besikhumba, ukuvuvukala, nokucasuka.
Ngomsebenzi wokuvimbela isikhumba, i-arbutin ingakhuthaza ukwanda kwama-keratinocyte futhi ithuthukise umsebenzi wokuvimbela isikhumba. Ucwaningo selukhombisile ukuthi ngemuva kokusebenzisa imikhiqizo ye-skincare equkethe i-arbutin amasonto ama-4, ukulahleka kwamanzi e-transcutaneous (TEWL) esikhumbeni kwehla ngo-25% futhi okuqukethwe komswakama esikhumbeni kukhuphuka ngo-30%.
3. Isicelo kanye namathemba esikhathi esizayo
Emkhakheni wezimonyo, i-arbutin isetshenziswe kabanzi ku-essence, ukhilimu wobuso, imaski yobuso neminye imikhiqizo yokunakekelwa kwesikhumba. Umthelela wayo wokusebenzisana onezithako ezifana ne-niacinamide novithamini C unikeza amathuba amasha kubakhi bezinto ezintsha. Njengamanje, usayizi wemakethe wemikhiqizo ye-skincare equkethe i-arbutin idlule i-1 billion yamadola aseMelika, ngezinga lokukhula lonyaka elingaphezu kuka-15%.
Emkhakheni wezokwelapha, i-arbutin ibonise amathemba okusebenza abanzi. Ucwaningo luye lwabonisa ukuthi inemisebenzi ehlukahlukene yezinto eziphilayo ezifana ne-antibacterial, anti-inflammatory, kanye ne-anti-tumor properties, futhi inemiphumela ebalulekile yokwelapha ekwelapheni izifo zesikhumba ezifana ne-melasma kanye ne-post inflammatory pigmentation. Izidakamizwa eziningi eziqanjiwe ezisuselwe ku-arbutin zingene esigabeni sesilingo somtholampilo.
Ngokukhula kwesidingo sabathengi sezithako ezimhlophe eziphephile nezisebenzayo, ithemba lemakethe ye-arbutin libanzi kakhulu. Ukuvela kwe-arbutin akulethanga izinguquko ezinhlotsheni kuphela ekwenziweni mhlophe nasekunakekeleni isikhumba, kodwa futhi kunikeze ukukhetha okuhle kubathengi besimanje abaphishekela ukunakekelwa kwesikhumba okuphephile nokusebenzayo. Lesi sithako esimhlophe semvelo nesiqinisekiswe ngokwesayensi sibhala isahluko esisha ekunakekelweni kwesikhumba.
