Serum mixed with a lot of extracts, less water. Which substance do you use to help reduce stickiness?
Can I use this substance? because I saw the recipe using Pitera 90%
Glycerin Gel 10%
* Use pure extracts without mixing water.
Serum base, gooey oil on the skin. What substance do I need to use to help it dry quickly and not see it? Please ask for advice. Thank you.
