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%
