Dr. Irwin's Review:
SkinCeuticals made it's name originally by making the best antioxidants, and this one is no exception. 3 antioxidants in one, it contains L-ascorbic acid 10%, phoretin 2%, and ferrulic acid 0.5%. My personal antioxidant under my sunscreen. The same high quality without the glass jars - love the new closed pump with it's travel friendly packaging. Oxidizes only minimally with time (turns slightly yellow).
Who It's For: All but sensitive skin. If you are sensitive, try this in a small amount for a few days on a test area.
How to Use: Apply after cleansing and under your moisturizer and/or sunscreen.
Size: 1 fl oz
Ingredients: 2% Phloretin, 10% L-Ascorbic Acid (vitamin C), 0.5% Ferulic Acid
