Hello, this formula cannot be mixed because Vitamin C type L-ascorbic acid cannot be stable in water. Please check usage restrictions. L-ascorbic acid on the product detail page.

L-ascorbic acid is not advisable as it is unstable and requires several other stabilizers to function. L-ascorbic acid decays the slowest. So the formula is more complicated than usual. This one is copied from the page L-ascorbic acid
Vitamin C type L-ascorbic acid should not be directly mixed with water. due to oxidation and deterioration (To mix with water directly Should be used within 3 days) used to mix in cosmetics. If water is included, it should be added Ferulic Acid and Vitamin E to reduce oxidation (adding Ferulic Acid and Vitamin E to reduce oxidation is copyright of SkinCeuticals Please click to see how) or add Glutathione (L-Reduced type) to reduce oxidation causing L-ascorbic acid No loss
Derivative recommended วิตามินซี that is easy to use, water soluble, for example Ethyl Ascorbic acid, Magnesium Ascorbyl Phosphate (MAP)
