Reasoning: why this verdict

Ferulic acid is best known for stabilizing vitamin C. In Lin et al. (2005), ferulic acid added to a vitamin C and E solution improved its chemical stability and doubled the skin photoprotection. It is one of the best-documented ingredient combinations in skincare.123

Who should be careful: Pure L-ascorbic acid serums are acidic and can sting. People with very sensitive skin, rosacea or eczema should patch test new products first.

How to use Vitamin C and Ferulic Acid together
