Serum Formulation with Copper Peptide and Azelaic Acid
Question
I would like to make a serum with the following ingredients and percentages. Could you please confirm if this formula is correct and provide the mixing instructions?
1. Distilled Water: Remaining part
2. Phenoxyethanol SA: 1%
3. Copper Peptide: 2%
4. Azelaic Acid: 6 %
5. SiliSolve: 1%
6. Cyclomethicone: 10%
How should I mix these ingredients?
Answer
Okay, I can help with that. Based on the staff's recommendation, here is a revised formula and instructions for your Copper Peptide and Azelaic Acid serum (100ml):
Revised Formula:
- Distilled Water: 80%
- Phenoxyethanol SA (Preservative): 1%
- Copper Peptide: 2%
- Azelaic Acid: 6%
- SiliSolve: 1%
- Cyclomethicone: 10%
The staff recommended using SiliSolve instead of SiliSolve Plus because your formula does not contain oil. They also added a preservative (Phenoxyethanol SA) and suggested Cyclomethicone as the silicone component.
Mixing Instructions:
- Combine SiliSolve (1%) and Cyclomethicone (10%). Mix or blend until well combined. This is the silicone phase.
- Combine Distilled Water (80%), Copper Peptide (2%), and Azelaic Acid (6%). Mix or blend until well combined. This is the water phase.
- Gradually add the water phase to the silicone phase in small amounts, mixing or blending continuously until fully incorporated.
- Finally, add Phenoxyethanol SA (1%) and mix until uniform.
This revised formula includes a preservative for stability and uses the recommended silicone and emulsifier for a serum texture suitable for combination skin.
