The effect of ferulic acid
Ferulic acid is used more as a kind of medicine, and it is also widely used as antioxidant in the food industry. In recent years, ferulic acid has also begun to be used in the cosmetics industry. Ferulic acid in the skin care industry is mainly based on the whitening and antioxidant effects of ferulic acid:
It has been reported that ferulic acid can inhibit or reduce the proliferation activity of melanocytes. The use of 0.1-0.5% ferulic acid solution can reduce the number of melanocytes from 117±23/mm2 to 39±7/mm2; at the same time, Ah Fuulic acid can also inhibit the activity of tyrosinase. A ferulic acid solution with a concentration of 5mmol/L can inhibit the activity of tyrosinase as high as 86%. Even if the concentration of ferulic acid solution is only 0.5mmol/L, its inhibition rate of tyrosinase activity can reach about 35%.
In addition, ferulic acid also has the effect of scavenging oxygen free radicals and good anti-oxidation. It is also reported that ferulic acid has sunscreen ability. Ferulic acid can effectively absorb ultraviolet rays in the wavelength range of 290-330nm to prevent or reduce ultraviolet rays of this wavelength. Damage to the skin
- Ferulic acid can sunscreen
The chemical black name of ferulic acid is 4-hydroxy 3-methoxy cinnamic acid. ——Does it sound familiar to you? If you remember that we talked about sunscreens before, one of the most commonly used sunscreens is called “Ethylhexyl Methoxycinnamate (OMC)”. Therefore, as a relative of the cinnamic acid family, ferulic acid is also absorbed The role of UV sunscreen. It is also recognized as one of the sunscreens in Japan.
- Ferulic acid can resist oxidation
We all know that ultraviolet rays can create “terrorists with bombs”-all kinds of free radicals with electrons on our skin. These terrorists scurry around and cause a series of cell damage, which will make the skin age down. This is photoaging. Compared with general sunscreens, ferulic acid can also resist oxidation and eliminate free radicals.
- Ferulic acid can fight inflammation
We have said that allergies and inflammatory reactions are actually the accidental injuries to the body caused by the “bullet flying” by the immune system of our body’s guard force when it catches invaders. On the one hand, ferulic acid can disarm the immune system (cutting off the key links in inhibiting inflammation, such as affecting the metabolism of arachidonic acid and inhibiting the synthesis of prostaglandin PEG2), and it can also calm the immune system so that they do not become excited (reduce hypertrophy) Cell activation), can play an anti-inflammatory and anti-allergic effect.
Ferulic acid is combined with the famous difid yeast, both of which have the effect of resisting photoaging, anti-inflammatory and maintaining stability, so it has a good effect on first aid and soothing of sensitive skin.
- Ferulic acid can whiten
We know that tyrosinase is the most critical enzyme needed by melanocytes to produce melanin. Ferulic acid can inhibit the production and activity of tyrosinase, thereby achieving the whitening effect of reducing the production of melanin.
