Ferulic Acid for Anti-aging


1. What is Ferulic Acid?

Ferulic Acid, which is chemically named 4-hydroxy-3-methoxycinnamic acid and is essentially a botanical phenolic acid, was earlier extracted from Ferula plants.


Nowadays, Ferulic Acid is mainly extracted from wheat bran, angelica, Ferulic grass, Rhizoma Chuanxiong, and horsetail. The characteristics of small molecules and low water solubility make it easy to enter the skin to play a role, and its PH value is acidic. If it is a main ferulic acid essence, its PH value must be stable between 3.5-5.5.


2. Function of Ferulic Acid

1) Whitening

Tyrosinase is a key enzyme that melanocytes need to make melanin, and ferulic acid is similar in structure to tyrosine.

Therefore, it can inhibit the formation of melanin by inhibiting the activity of tyrosinase through the competition of tyrosine. At the same time, it can also inhibit the activity of melanocyte B16V to achieve the whitening effect.


2) Sun Protection

Vitamins and polyphenols are the most commonly used natural sunscreen ingredients. Ferulic acid, as an acid phenol, contains double bonds and phenols in its molecular structure, which has a certain resistance to ultraviolet rays.

Ferulic acid itself is a sunscreen that effectively absorbs UVB rays in the 290nm to 330nm wavelength range. However, ferulic acid will be very unstable after encountering ultraviolet ray, and it needs to be kept away from light. At the same time, it should also pay attention to do a good job of sunscreen when using in the daytime.


3) Antioxidant

We know that free radicals can cause the formation of reactive oxygen species in the skin and destroy collagen, hyaluronic acid and skin cell skills in the skin. Antioxidant is also the process of fighting free radicals to a certain extent, and ferulic acid has the antioxidant effect of eliminating free radicals.

The free radicals in the skin react firstly with vitamin E, then with vitamin C. Finally, glutathione acts on nicotinamide adenine dinucleotide phosphate (NADP). These processes require large amounts of antioxidants, and they work independently.


4) Anti-inflammatory and stability maintenance

Ferulic acid can directly fight inflammatory mediators, inhibit the synthesis or release of PEG2 (prostaglandin, which can induce inflammation), reduce capillary permeability, and play a role in fighting inflammation and maintaining skin stability.


3. Safety of Ferulic Acid

Ferulic acid is extracted from plants (mostly from angelica sinensis, Chuanxiong), but also from wheat. These are edible medicinal materials, so safety is guaranteed. In addition, ferulic acid is absorbed by the human body and can be discharged from the urine without accumulating in the human body and causing cumulative toxicity.

Ferulic acid is a safe ingredient that is easy to metabolize and absorb for most skin types, but be cautious if you are allergic to wheat.

Ferulic acid produced by Kingherbs Limited has antioxidant effect, which helps to slow down skin aging and improve skin elasticity. At the same time, it can also promote the synthesis of collagen, effectively improve skin resistance, and make skin healthier, young and energetic.
