# What percentage of vitamin C is in your Vitamins C+E+Ferulic Serum?
Vitamins C+E+Ferulic Serum is formulated with both stabilized l-ascorbic acid + two C derivatives, magnesium ascorbyl phosphate (MAP), and Tetrahexyldecyl Ascorbate (THD).
It also includes additional antioxidants such as Astaxanthin and Lycopene, increasing overall potency for skin that can tolerate l-ascorbic acid. Essential oils have been eliminated to reduce the potential for skin irritation.
The total percentage of Vitamin C (l-ascorbic and C derivatives) is roughly 7%.
