Ferulic acid

Ferulic acid — a plant-derived anti-oxidant and free-radical scavenger, it protects the skin against UVB-induced redness. When incorporated into formulas with ascorbic acid and tocopherol, ferulic acid can improve their stability and double the photoprotection capacities offered by the formulation. In clinical studies, ferulic acid exhibits good permeation capacities through the stratum corneum, which can be attributed to its lipophilic properties. The combination of vitamin C, E and ferulic acid appears to have clear advantages over vitamin C alone.
