Figure 4 illustrates the antimicrobial mechanisms of polyphenols, illustrating the disruption of microbial cell structures (lipopolysaccharide cell wall, peptidoglycan cell wall, phospholipid bilayers, cell membrane proteins) and the impairment of essential cellular functions (inhibition of DNA gyrase and RNA synthesis, pore formation causing leakage, damage to membrane lipid bilayers, inhibition of enzyme activity, disruption of cell wall biosynthesis, and inactivation of lipopolysaccharide) in bacteria such as S
T/T individuals supplementing with 5-methylfolate (active folate), methylcobalamin, and pyridoxal-5'-phosphate normalize homocysteine, restore BH4 recycling, and reduce functional methylation insufficiency across most downstream longevity mechanisms

The majority of the available studies include only short-term observations (a few weeks), making it impossible to assess the long-term effects of KD on the skin
