Dab tsi yog cov haujlwm ntawm cov khoom?

1. Muaj ntau yam tshuaj tua kab mob, hauv vitro siv cov nyhuv muaj zog;

2. Tsawg concentration tuaj yeem cuam tshuam cov haujlwm ntawm collagenase, tiv thaiv kab mob caries thiab tawv nqaij tiv thaiv wrinkle nyhuv

3. Nws muaj zog thiab dav-spectrum antioxidant kev ua, uas muaj peev xwm inhibit lub tiam ntawm lipid peroxide;

4. Qhov txo qis thiab poob ntawm filagin nyob rau hauv lub cortex tej zaum yuav yog lub ntsiab ua rau cov tawv nqaij qhuav kab mob xws li atopic dermatitis, thiab kev txhawb nqa ntawm filagin ntau lawm los ntawm caffeic acid qhia tau hais tias nws muaj anti-inflammatory teebmeem ntawm daim tawv nqaij.

5. kuj tuaj yeem siv rau hauv cov khoom siv kho hniav dawb

6. Nws kuj muaj lub luag haujlwm ntawm absorbing ultraviolet lub teeb

Kev taw qhia ntawm daim ntawv thov

Siv rau hauv cov tshuaj pleev ib ce, nws tuaj yeem nqus tau ultraviolet rays, whiten thiab anti-aging

Tsawg concentration muaj cov nyhuv inhibiting ntawm daim tawv nqaij melanin ntau lawm, thiab qhov ntau npaum li cas ntawm whitening cosmetic khoom yog 0 5-2 feem pua. Nws tuaj yeem siv los ua tus neeg sawv cev pabcuam rau oxidative plaub hau dyes, uas muaj txiaj ntsig zoo los txhim kho qhov kev siv ntawm cov xim.
