● Kutheni le nto umzimba womntu uvelisa uMoyanin?
Ukuvezwa kwelanga yeyona nto iphambili kwimveliso ye-mpundo. I-Ultraviolet imitha kwilanga elanyangeni i-Deoxyribonucleic Acid, okanye iDNA, kwiiseli. I-DNA eyonakalisiweyo inokukhokelela kumonakalo kunye nokukhutshelwa kolwazi lwendalo, kwaye nokuba ibangele utshintsho lwe-genign, okanye ilahleko ye-gener i-tumor i-turussor yemfuyo, ekhokelela ekusenokwenzekani kwamathumba.
Nangona kunjalo, ukuvezwa kwelanga akunjalo "kubi", kwaye yonke le "tyala" kwi-melanin. Ngapha koko, kumaxesha anzima, i-melanin iya kukhutshwa, ifumane amandla omzimba we-ultraviolet, ukuthintela i-DNA ukuba ingonakalisi, ngaloo ndlela kunciphisa umonakalo obangelwe ngumzimba we-ultraviolet emzimbeni. Nangona uMelanin ekhusela umzimba womntu ovela kumonakalo we-ultraviot, unokwenza umkhuhlane wethu kwaye uphuhlise amabala. Ke ngoko, ukuvimba imveliso ye-melanin yindlela ebalulekileyo yolusu emhlophe kwishishini lobuhle.
● YintoniI-arbutin?
I-Arbutin, ekwabizwa ngokuba yiArbutin, inefomula yekhemikhali ye-C12H16O7O7. Sisithako esikhutshwe kumagqabi e-Erinaceae Tall Pobry. Ingathintela umsebenzi weTyrosinasase emzimbeni kwaye kuthintele imveliso ye-melanin, ngaloo ndlela kuncitshiswa kolusu, ukususa amabala kunye ne-frets. Ikwaneziphumo ze-bactericidal kunye ne-anti-insulmatory kwaye isetyenziswa ikakhulu kwiziko leziko.
I-arbutinInokwahlulwa kuphela ngohlobo lwe-α-β-chwethe ngokwakhiwe. Umahluko omkhulu phakathi kwezi zinto zimbini kwiipropathi zomzimba kukujikeleza okukhethileyo: I-α-Arbutin imalunga ne-180 degrees, ngelixa i-β-i-arbutin imalunga ne -60. Zombini zinefuthe lokuvula i-tyrosinase ukufezekisa imhlophe. Eyona nto isetyenziswa kakhulu ngu-β-uhlobo oluphantsi. Nangona kunjalo, ngokutsho koPhando, ukongeza uhlobo lwe-α elilingana ne-1/9 yoxinzelelo lwe-β-chwethelela unxibelelwano lwe-tyrosinase kwaye luphumelele imhlophe. Uninzi lweemveliso zonyango ezine-α-arbutin inefuthe eliphindwe kali-14 ngaphezulu kwe-arbutin yemveli.
● Zithini izibonelelo zeI-arbutin?
I-Arbutin ikhutshiwe ikakhulu kumagqabi e-Bhebberry. Ingafumaneka kwezinye iziqhamo kunye nezinye izityalo. Inefuthe lokuqaqambisa ulusu. Inokungena ngokukhawuleza ulusu ngaphandle kokuchaphazela iiseli zolusu. Idibanisa ne-tyrosine, ebangela ukuveliswa kwe-melanin, kwaye inokuthi ivimbe ngokufanelekileyo umsebenzi weTyrosinase kunye nokuveliswa kwe-melanin, ukukhawulezisa i-melanin. Ukongeza, i-arbutin inokukhusela ulusu ukusuka kwi-radicals yasimahla kwaye ine-hydrophicicity elungileyo. Ke ngoko, ihlala yongezwa kwimveliso ekhawulezileyo emarikeni, ngakumbi kumazwe aseAsia.
I-arbutinyinto esebenzayo yendalo evela kwizityalo eziluhlaza. Licandelo le-sokoriking yesikhumba elidibanisa "izityalo eziluhlaza, ezikhuselekileyo nenokuthenjwa" kunye "nendalo esebenzayo". Inokungena ngokukhawuleza kulusu. Ngaphandle kokuchaphazela uxinzelelo lweseli, inokuthintela ukusebenza kweTyrosinasase kulusu kwaye ithintele ukumiswa kwe-melanin. Ngokudibanisa ngokuthe ngqo nge-tyrosinase, ikhawulezisa i-Delanin, ukunciphisa i-melanin, ngaloo ndlela kunciphisa iziqwengana kunye nokususa amabala kunye nokucaphukisa, ukucaphukisa, ubuntu obunengxaki kunye nezinye iziphumo ebezingalindelekanga. Ikwaneziphumo ze-bactericidal kunye ne-anti-insulmatory. Yeyona ndawo ikhuselekileyo neyona iphumelelayo ye-white ehle kakhulu emhlophe namhlanje, kwaye kukwangumthengisi ofanelekileyo we-whiteling kunye ne-freckle esebenzayo kwinkulungwane yama-21.
● Yintoni eyona nto iphambili kuyoI-arbutin?
Ingasetyenziswa kwizinto eziphakamileyo ze-reasmetics kwaye zinokwenziwa kwi-cream yokhathalelo lolusu, i-freakle cream, i-periarl ephezulu yeperile, njl.
Izinto ezingafunekiyo zokutshisa kunye nonyango lwe-Scald: I-Arbutin sisithako esiyintloko sokutshisa okutsha kunye nonyango oluqinileyo, ukuvuselelwa okuchasene nokudumba, ukuphiliswa okungxamisekileyo, kwaye akukho zizathu zikhawulezayo.
Ifomu ye-dosage: ukutshiza okanye ukufaka isicelo.
Izinto ezingafunekiyo ze-Antinal Anti-I-Indermatic Machinary: I-Bactericidal elungileyo kunye ne-anti-inflicidal, akukho ziphumo zinetyhefu.
