Please inquire. Guaiazulene (Oil Soluble, 98% Purity) can be distributed in drops of Hiya serum. Or can I get nourishing cream?
- Does it depend on the brand of Hiya serum or cream you use?
- If you can't mix and store it for use. Can it be made into drops to mix when using?
- Please give me some advice. If you can drop and mix, let's say 50 mL of serum, how many grams do you need to drop to get ~0.1%? (I'm not sure of the calculation.) This is based on the recommended usage rate: 0.05-0.5%.
