Kojic Acid and Vitamin C in the same formulation.

Hi there chemists. Can I have both Kojic acid and Vitamin C in the same serum formulation? is there risk of irritation to consumers? or interaction between the two actives.

    Sure you can use them in the same formula. 
    No, there really isn't any reaction between them.
    There is always an irritation risk when using kojic acid in any product. You'll have to test it.
