Ferulic acid is a plant-based antioxidant phytochemical found in grains like, rice bran, wheat bran, oats, coffee, apples and oranges known for protecting cells from damage by neutralizing free radicals, which helps slow skin aging (wrinkles, sunspots) and reduces inflammation, often used in skincare to boost Vitamin C and E stability and effectiveness. Ferulic acid is a powerful plant-derived antioxidant widely used in cosmetics and dermatology, especially in advanced skincare formulations.
