Ferulic acid, also known as hydroxycinnamic acid,is a powerful antioxidant that can neutralize pollution and the damage of free radicals caused by ultraviolet or infrared radiation, all of which accelerate skin aging.
High compatibility of ferulic acid with other ingredients:
Although the antioxidant effect of a single ferulic acid is also excellent, it still has some unavoidable problems, such as stability, ferulic acid is active and easily oxidized, and it is also degraded by the influence of pH and temperature. . Therefore, in order to enhance the activity of the ingredients and the stability of the formulation, ferulic acid is often used in combination with other ingredients, and some compound ingredient combinations have even become classics.
Stable formula: "CEF" combination
Among the many combinations of ferulic acid, "CEF" is the most famous. In 2005, American researchers found that ferulic acid can improve the chemical stability of vitamins (C+E). Skin photoprotection under sun exposure is increased by 4-8 times. "CEF" as a solid antioxidant combination, the combination of the three, its efficacy has also been improved. Studies have shown that the UV protection effect of the "CEF" combination exceeds that of idebenone and coenzyme Q10.
A synergistic combination of ferulic acid
Ferulic and polyacids: Cosmetic brands have studied C8-lipoic acid and say that adding "keratolytics" (such as fatty hydroxycarbons) to ferulic acid enhances its efficacy. However, some dermatologists believe that "exfoliating acids" can alter the pH of the skin, thereby affecting the antioxidant properties of ferulic acid. Therefore, superimposing acid components on the skin is more demanding in terms of product formulation and technology. Ferulic acid and resveratrol: Both ferulic acid and resveratrol are considered to be really effective antioxidants, and both can be used for whitening. This combination is also a typical combination of synergistic whitening. It is used in many Among the products with anti-oxidant and whitening effects. Ferulic acid and retinol: The combination of ferulic acid and retinol can enhance anti-aging effects, while ferulic acid can properly reduce the irritating effect of retinol, neutralize free radicals produced by retinol and reduce sunlight harm.
