Ferulic acid has a secret weapon—phenolic hydroxyl. This structure is best to fight free radicals. It is extremely lethal to superoxide free radicals and hydroxyl free radicals. It can effectively capture the lone pair of electrons of free radicals and make free radicals change. It is a stable molecule that blocks electron transfer and protects the body from oxidative damage.
Ferulic acid has a phenolic acid structure. It is a weakly acidic organic acid. It is also a tyrosinase inhibitor that can be compatible with various strong antioxidants (such as resveratrol, vitamin C, etc.), which can both whiten and anti-oxidize. , And a multi-effect product that can prevent and reduce inflammation.
Ferulic acid can not only inhibit the activity of melanocyte B16V, but also inhibit the activity of tyrosinase (whitening dual pathway, I am afraid you are not white). The 5mmol/L ferulic acid solution can inhibit tyrosinase activity as high as 86%. Even if 0.5mmol/L, its inhibition rate of tyrosinase activity can reach about 35%
VC (ascorbic acid) can directly scavenge free radicals in the water phase and protect cell membranes; VE (tocopherol) can scavenge free radicals in the oil phase by inhibiting lipid oxidation. Therefore, the compatibility of VC and VE can be synergistic. Compounding ferulic acid into a formula containing VC and/or VE can enhance the antioxidant and whitening effect of VC and VE, and improve their chemical stability in the system, and its photoprotective effect is better than using vitamin C alone. The formula with E is about twice as much. Therefore, C+E+F can be used as a supplement to daily sun protection.
Ferulic acid also has anti-inflammatory effects and broad-spectrum anti-allergic effects. The inhibitory rate of 4μmol/L ferulic acid on interleukin IL-4 is 18.2%.
