What is Ferulic Acid?

You’ll find that ferulic acid is derived from a number of grains, such as oats, rice and sometimes apple seeds. Often included into skincare formulations containing vitamin C to help balance and stabilise the notoriously tricky vitamin. Packed with antioxidants it has the ability to combat uneven skin tone, signs of premature ageing, inflamed skin and other signs of pigmentation. All of these concerns occur when the skin comes into contact with free radicals that transfer onto the face as soon as you step foot outside, pollution, sun exposure and even freezing temperatures all contribute the damage.
