Uphononongo lufumene ukuba i-arbutin ene-concentration ye-3% ineempawu ezintle, i-cytotoxicity ephantsi, ukucaphuka kunye nokwaliwa, kunye nomda ophezulu wokugxininiswa kwayo awukwazi ukudlula i-7%.Uxinaniso oluphezulu lwe-arbutin luya kutshabalalisa ulusu oluqhelekileyo.Isithako sayo esisebenzayo sendalo, i-glucopyranoside, inempembelelo enamandla yokuthintela kwi-tyrosinase yabantu kune-arbutin, kwaye ithatha indawo ye-arbutin kuba isebenza ngakumbi kwaye izinzile.

2. I-Licorice Extract

Izinto zayo ezisebenzayo ziyi-liquiritin, i-isoliquiritin kunye ne-licorice flavonoids.I-Liquiritin yenza i-melanin yesikhumba isasazwe ngokulinganayo ngokusasaza i-melanin ehlanganisiweyo, kwaye ifezekisa umphumo wobumhlophe;umsebenzi ophambili we-licorice flavonoids kukuthintela umsebenzi we-tyrosinase, i-DHICA oxidase kunye ne-dopa pigment intermutase.

Uphononongo lufumanise ukuba iimveliso zokhathalelo lwesikhumba zonyango eziqulethe i-licorice extract kunye ne-papain zinokunceda i-melasma kunye ne-post-inflammatory hyperpigmentation, kunye nokusabela okungathandekiyo, kwaye zineempawu ezithile .. kunye ....Ukugxininiswa kwayo kwiimveliso ezimhlophe yi-10% ukuya kwi-40%, kodwa umxholo wezithako ezisebenzayo kwi-licorice awuphezulu kwaye ukucocwa kunzima kwaye kuyabiza.

3. Chuanxiong Extract

Uphononongo lufumene ukuba i-Chuanxiong extract inokuthintela ngokufanelekileyo umsebenzi we-tyrosinase, ebonisa umphumo wokukhuphisana.I-ointment ye-Chuanqiong iphuhliswe ngefomula edibeneyo ye-emulsifiers eyahlukeneyo kunye ne-thickeners eyahlukeneyo, uphando malunga nokusebenza kwayo mhlophe kunye nokusebenza kwabonisa ukuba i-0.5% ~ 1.0% i-Chuanqiong i-ointment ineempawu zokuzinza okulungileyo, ukusebenza okuphezulu kunye nesiphumo esihle sokwenza mhlophe.
