Mixing Vitamin C E Ferulic with Alpha Arbutin

Yes, it is possible to mix the Vitamin C E Ferulic pre-mix kit with Alpha Arbutin.

Based on the product information, Alpha Arbutin is a water-soluble ingredient that can be added to formulations. When incorporating Alpha Arbutin, ensure the final mixture is at a temperature below 30°C and the pH is between 3.5 and 6.5. Avoid mixing Alpha Arbutin into formulations with a pH higher than 8, as this can cause it to break down.

As the staff member suggested, the Vitamin C E Ferulic formula itself is highly effective due to its stabilized Ascorbic Acid. You might consider trying the Vitamin C E Ferulic alone first to see its results before adding Alpha Arbutin, especially since Alpha Arbutin can be more costly.
