- Repair Activator™ 10%
- Acetyl Hexapeptide-8 (Argireline) 10%

Could you please provide feedback on the compatibility, stability, and recommended usage concentrations for these ingredients, especially considering the base and overall percentages?
Answer
Hello,
I have reviewed the formulations you sent, based on the advice from our expert team. Here are the suggestions:
For the Night Gel:
- Slim-Coffee™: This ingredient is an electrolyte and may cause the gel texture to become liquid. The team recommends omitting it, especially if you are new to formulating.
- Other Ingredients: The remaining ingredients are compatible.
- Texture: Using a relatively high percentage of many active ingredients means the Aloe Vera Gel (Lite) base is only 59%, which might result in a rather liquid texture.
For the Daytime Spray:
- DMAE (SkinTight MD™) Liquid: For skin that has not used DMAE before, a concentration of 15% is quite high and may cause irritation. The team recommends starting at a low level, not exceeding 5%.
- Panthenol (Vitamin B5) ExtraLite™: A concentration of 5% is considered quite high for normal skin. The team suggests that 2% is sufficient.
Additional Recommendations from the Team:
- In fact, using just the first gel formula might be sufficient.
- You may consider adding Panthenol (Vitamin B5) ExtraLite™ at 1-2% to the gel formula (while reducing the proportion of some other ingredients, such as Safe-B3™ to 5%) and use it both morning and evening. You can apply a thicker layer in the evening.
- DMAE cannot be added to the gel formula because it is a high electrolyte and will cause the gel to turn into water.
You can consider adjusting your formulas based on these recommendations before placing your order.
