"I use the SkinCeuticals C E Ferulic ($166) every morning to give my skin extra protection against sun damage and environmental aggressors. Five drops in the morning boost UVA/UVB ray protection by protecting against free radical damage. It's a multi-functioning product that will improve texture and appearance. I consider CE Ferulic the gold standard for topical antioxidants. It is backed by copious clinical studies and is widely lauded by dermatologists (myself included)."
