The effect of ferulic acid on the skin
Ferulic acid is used more as a kind of medicine, and it is also widely used for 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
The safety of ferulic acid
Ferulic acid is found in the natural plant Angelica sinensis, which is used as an edible Chinese medicine. Therefore, the security is relatively high. Modern research shows that ferulic acid can be absorbed by the human body and excreted in the urine in time, and will not accumulate in the human body and cause accumulated toxicity. In particular, ferulic acid is easily metabolized by the human body, has extremely low toxicity, and is relatively safe to use. It is precisely because of this that ferulic acid is widely used in medicine and food industry.
