Question
My serum formulation is yellow and I want it to be clear. It also absorbs slowly and feels slightly sticky. How can I fix these issues? Is the yellow color caused by Licorice Extract (Licochalcone A)?
Answer
Based on your serum formulation and the issues you encountered (yellow color, slow absorption, and slight stickiness), here is the guidance:
Regarding the yellow color: The staff confirmed that the yellow color comes from the Licorice Extract (Licochalcone A) in your formula. To achieve a clear serum, you should remove this ingredient.
Regarding slow absorption and stickiness: To improve the absorption speed and give the serum a smoother, less sticky feel, the staff recommended adding Silicone Gel (Vinyl Dimethicone Crosspolymer).
- Usage: Add Silicone Gel at a concentration of 10% to your current formula. You can mix or blend it into the existing serum until fully incorporated.
