Stabilized Vitamin C (Natural-C Glycol™) Serum is if you buy it and have to mix again. or can apply at all Please inquire as follows. 1. This one has a PH3 value while there is a requirement to use PH3.5 or higher. So I think that it should be bought for mixing with other substances, right? Please suggest what substances to add.

I apologize, you don't have to mix it. I bought it and used it so I didn't mix anything. If your skin is not very sensitive, you don't have to worry about pH, but I recommend you to do a allergy test first. If you've never used acid at all, it may burn.

Can it be used both during the day and at night, or is it just for use at night before going to bed?
