Serum 10 is a vitamin C serum formulated under the Duke Antioxidant patent. The Duke Antioxidant patent describes effective delivery of vitamin C to skin. In order for a vitamin C serum to be effective it must be formulated with pure l-ascorbic acid (vitamin C) at an acidic pH within the 2.0-3.5 pH range and have a concentration between 10-20%. SkinCeuticals is the only brand to formulate according to these parameters.
All SkinCeuticals antioxidant formulations have been tested in final packaging and have been confirmed to remain stable and effective for 36 months, and up to 6 months after opening. L-ascorbic acid (pure vitamin C) is known to change color with time, however oxidation is minimal in SkinCeuticals antioxidant and the formulation is proven to remain effective.
How to use
It is normal for vitamin C products to darken after opening due to air and light exposure.
Any change in colour does not affect the product's efficacy.
