Ferulic Acid Briefly
Ferulic acid is a phenolic acid derived from cinnamic acid. It is named after the species Ferula (giant fennel), a group of herbaceous plants belonging to the large family of Apiaceae. Ferulic acid is found in some fruits and vegetables such as spinach and rhubarb, as well as in cereals (oats, rye, corn) and tree bark (fir and pine).
One of the most significant properties of ferulic acid is its antioxidant action, i.e. its ability to neutralize free radicals. In this way, it protects the skin from damage caused by oxidative stress and slows down skin aging.
In cosmetics, it is usually used in serums, creams, lotions and cleansers to make the skin more radiant, firmer and smoother. In addition, the active ingredient can fade pigmentation spots and prevent their formation.

The Dangers and Side Effects of Ferulic Acid
When used cosmetically, ferulic acid is usually safe for the skin and human health. This mild antioxidant is excellently tolerated by the epidermis and has few side effects. In rare cases, a treatment with ferulic acid may cause mild irritation and/or redness, as well as itching.
Before adding a product containing ferulic acid to your skin care routine, we recommend that you perform a skin tolerance test. To do this, apply a few drops of the product to the crook of your arm and wait a few moments. If you experience skin reactions of any kind, you should not use this skincare on your face.
Contraindications of Ferulic Acid
Ferulic acid should not be combined with retinoids or vitamin A-based products. In addition, ferulic acid is not photosensitizing and is not contraindicated when used in the morning. Just remember to protect yourself from UV rays with a broad-spectrum sunscreen.
