Ferulic acid is a kind of phenolic acid (soluble in hot water, slightly soluble in cold water, and poor stability in aqueous solution). Its chemical name is 4-hydroxy-3-methoxycinnamic acid, which exists in ferulic acid. , Angelica, Chuanxiong, Horsetail, Cohosh and other Chinese herbal medicines. A very small amount of ferulic acid exists in free form in plants, a small part of it combines with fat-soluble substances (sterols, etc.) to form oryzanol, and most of ferulic acid interacts with lignin, polysaccharides and proteins in cells through ester bonds and ether bonds And so on combined to become the skeleton of the cell wall.
Ferulic acid is used in the field of cosmetics. It can effectively resist ultraviolet radiation and inhibit the activity of tyrosinase and melanocytes. It has anti-wrinkle, anti-aging, anti-oxidation and whitening effects.
Ferulic acid has a strong antioxidant effect, and has the effect of inhibiting tyrosinase, which can reduce the production of melanin;
Ferulic acid has good ultraviolet absorption around 290-330nm, and ultraviolet rays of 305-315nm are most likely to induce skin erythema. Ferulic acid and its derivatives can reduce the toxic and side effects of high-dose UVB radiation on melanocytes, and affect the epidermis. Certain light protection;
Whitening effect. The structure of ferulic acid is similar to that of tyrosinase and levodopa. It can competitively inhibit the activity of tyrosinase and reduce the production of melanin, thereby whitening the skin.
