Hello, the formula will have stability issues. Vitamin C , no problem in other parts. can mix Cyclomethicone It does not affect the pH of the formula Encapsulated Retinol (65K.IU/g) has a pH of approximately 4-6, which may result in a formula. The pH is slightly higher, but because it is used in small quantities. Therefore, it does not affect the pH so high that it affects the stability of Vitamin C but other ingredients Will have a greater impact on it, such as Pitera is used up to 45%. The team recommends members when the mix is finished and try. วัดค่า pH look again, so that Vitamin C has better stability, the formula should have a pH of not more than 3.5.
