Ferulic acid is an antioxidant found in plant cell walls, most notably in the brans of certain cereals, like oats and wheat. It can also be found in many fruits and vegetables such as apples and oranges. Ferulic acid has been used in skincare products for its anti-aging properties to improve skin health. Studies have shown that it can help reduce wrinkles, lighten sun spots, even out skin tone, and reduce inflammation. It can also act as a free radical scavenger to protect skin from environmental damage caused by UV radiation and pollution. Ferulic acid has also been found to increase the effectiveness of other active ingredients when added to a formulation due to its ability to increase their absorption into the skin.
