1. Arbutin

Nws yog ib qho tseem ceeb tyrosinase inhibitor, uas tuaj yeem cuam tshuam cov kev ua ntawm tyrosinase, thaiv cov synthesis ntawm dopa thiab dopaquinone, yog li inhibiting zus tau tej cov melanin, thiab tseem tuaj yeem txo cov pigmentation los ntawm ultraviolet rays, tab sis nws ruaj khov tsis zoo, nrog rau qee yam. photosensitivity.

Txoj kev tshawb no pom tias arbutin nrog ib qho concentration ntawm 3% muaj cov khoom zoo, tsis tshua muaj cytotoxicity, khaus thiab ua xua, thiab qhov siab tshaj ntawm nws cov concentration tsis tuaj yeem tshaj 7%. Ib tug siab concentration ntawm arbutin yuav decolorize ib txwm tawv nqaij. Nws cov khoom xyaw ntuj, glucopyranoside, muaj zog inhibitory nyhuv ntawm tib neeg tyrosinase dua arbutin, thiab hloov arbutin vim nws muaj txiaj ntsig zoo thiab ruaj khov.

2. Licorice Extract

Nws cov khoom xyaw nquag yog liquiritin, isoliquiritin thiab licorice flavonoids. Liquiritin ua rau cov tawv nqaij melanin sib npaug los ntawm dispersing lub aggregated melanin, thiab ua tiav cov nyhuv whitening; Lub luag haujlwm tseem ceeb ntawm licorice flavonoids yog inhibit qhov kev ua ntawm tyrosinase, DHICA oxidase thiab dopa pigment intermutase.

Cov kev tshawb fawb tau pom tias cov khoom kho mob ntawm daim tawv nqaij uas muaj licorice extract thiab papain tuaj yeem pab melasma thiab post-inflammatory hyperpigmentation, tsis tshua muaj kev phiv, thiab muaj qee yam .. thiab .. cov khoom. Nws cov concentration hauv cov khoom siv ntxuav hniav dawb yog 10% mus rau 40%, tab sis cov ntsiab lus ntawm cov khoom xyaw nquag hauv licorice tsis siab thiab kev ua kom huv yog nyuaj thiab kim.

3. Chuanxiong Extract

Cov kev tshawb fawb tau pom tias Chuanxiong extract tuaj yeem cuam tshuam cov haujlwm ntawm tyrosinase, uas qhia txog kev sib tw inhibitory nyhuv.
