Hello
1.Please suggest a substance that reduces ph in this formula (no water in the formula)
There is something wrong in the formula using Vitamin C at 15% must definitely lower the pH. Introduce members to check the formula, weighing, mixing process
2. Recommend substances that make the serum more concentrated and smoother. Thank you
The recipe as the member informed. can be thickened can by filling Pro Polymer , make it smoother. If the formula is thick enough (adding Pro Polymer ), it is recommended to use feeling modifier powder such as SiliSilk 3% or AminoSilk 3%

In anhydrous formulation, you can use pH Meter วัดค่า pH right?

Hello, if the formula does not contain water will be complicated to วัดค่า pH the easiest way is to dilute the formula in water, for example, at 50% of the formula + 50% of water, what is the pH value?
