2. Lub hauv paus ntsiab lus ntawm kev tiv thaiv oxidation: tshem tawm cov dawb radicals ntau dhau, ib qho ntawm cov kev ua haujlwm ntawm cov dawb radicals yog induce transcription factor (xws li AP-1 thiab NF-κB) kom nce kev qhia ntawm matrix metalloproteinases (MMP), ib qho ntawm uas yog collagen Enzymes, nws tuaj yeem ua rau collagen maj mam poob nws cov khoom qub, thiab daim tawv nqaij poob nws elasticity thiab wrinkles thiab sags.
3. Cov tshuaj antioxidants
▍Vitamin C
