Ferulic acid is an antioxidant that enhances the effects of vitamin C, according to Yadav. Found in various plants like grasses, grains, fruits, and flowers, ferulic acid is often recommended in conjunction with vitamin C. These two antioxidants work together to provide better protection against UV damage, making them a powerful pairing. Additionally, ferulic acid helps stabilize vitamin C, which is known to be unstable and easily breaks down without proper support.
Board-Certified Dermatologist, Elyse Love, MD, FAAD from GlamDerm, supports this view, stating that ferulic acid increases the stability and supports the antioxidant properties of vitamin C. By using these ingredients together, their potential is maximized.
The great thing about combining ferulic acid and vitamin C is that there are very few downsides or drawbacks. The only potential issue is irritation when using high percentages. Love explains that the tolerability of vitamin C depends on its form and concentration, with L-ascorbic acid being the most potent form. Concentrations of L-ascorbic acid range from 10-20%, and higher concentrations can potentially cause more irritation. It’s advised for individuals with sensitive skin to start with lower percentages or gentler vitamin C formulations to avoid irritation. For those seeking a serum designed for sensitive skin, Love suggests trying First Aid Beauty’s 10% Vitamin C Brightening Serum ($50).
