Feedback on Your Eye Serum Formulation

Thank you for sharing your eye serum formula and asking for feedback! It's great that you are formulating a product tailored to your needs. Your current formula includes several excellent ingredients for addressing wrinkles and overall skin health.

Your formula includes:

• Vitamin B3 (Niacinamide): A versatile ingredient known to help with skin barrier function, reduce inflammation, and potentially improve the appearance of dark circles by increasing blood flow.
• Argireline® and Matrixyl™ 3000: These are well-regarded peptides for targeting wrinkles. Argireline helps with expression lines, while Matrixyl 3000 supports collagen synthesis for age-related wrinkles. Using them together is a good approach for comprehensive wrinkle care around the eyes.
• Orange Peel Extract: This extract contains Hesperidin Methyl Chalcone, which is known to help stimulate blood flow and is suitable for addressing dark circles caused by poor circulation or inflammation.

To further enhance your formula to specifically target puffiness and potentially improve dark circles and hydration, here are some suggestions:

Suggestions for Improvement

1. Address Puffiness: Consider adding ingredients known for their ability to reduce swelling and improve circulation. Good options include:

   • Caffeine: Known to help constrict blood vessels and reduce fluid retention, which can significantly help with puffiness.
   • Green Tea Extract (Hi-EGCG™): Contains antioxidants and can help reduce inflammation and improve circulation.

2. Enhance Dark Circle Treatment: While Vitamin B3 and Orange Peel Extract are beneficial, you could also consider adding a stable form of Vitamin C, such as Ascorbyl Glucoside or Ethyl Ascorbic Acid. These are powerful antioxidants that can help brighten the skin and reduce hyperpigmentation. Note: Be mindful of compatibility when combining Vitamin C derivatives with Niacinamide; check supplier guidelines. Orange Peel Extract at 5% is already a good concentration for this purpose.

3. Boost Hydration: The skin around the eyes is thin and prone to dryness. Adding a hydrating ingredient can improve the appearance of fine lines and keep the area supple. Consider:

   • Hyaluronic Acid: A powerful humectant that draws moisture into the skin.
   • D-Panthenol (Pro-Vitamin B5): Helps to hydrate, soothe, and support the skin barrier.

4. Adjust Total Percentage: Your current formula adds up to 100.5%. You will need to slightly reduce the percentage of one or more ingredients (likely the distilled water or Silky Serum Base) to bring the total down to exactly 100%.

5. Review Ingredient Concentrations: The concentrations you've chosen for Argireline and Matrixyl 3000 (5% each) are within typical recommended ranges, assuming these are the standard solutions provided by suppliers. Vitamin B3 at 2% is a good starting point, but it can often be used effectively at higher concentrations (up to 10% for high-purity types like Safe-B3™) for increased benefits, including on dark circles.

6. Mixing Method and pH: Your mixing method (dissolving actives in water phase, combining with base, adding preservative) is generally correct. Ensure that the temperature remains below 40°C when adding heat-sensitive ingredients like the peptides and Orange Peel Extract. Also, check the optimal pH range for all your ingredients (Argireline, Matrixyl 3000, Vitamin B3, and Orange Peel Extract generally work well in a pH range of 3.5-7.0, but specific supplier recommendations should be followed). Some Vitamin C derivatives like Ascorbyl Glucoside require a specific pH (6.5-6.8) for stability and may have compatibility issues with Niacinamide.

Revised Formula Suggestion (Example)

Here is an example of how you might adjust your formula to include some of the suggestions, keeping the total at 100%. This is just a starting point and may require testing and further adjustment:

1. Distilled Water: 47.5%
2. Orange Peel Extract: 5%
3. Vitamin B3 (Safe-B3™): 5%
4. Argireline®: 5%
5. Matrixyl™ 3000: 5%
6. Encapsulated Caffeine: 2%
7. Hyaluronic Acid (Standard Molecule): 0.1%
8. D-Panthenol Care: 1%
9. Eye Preserved™: 0.5%
10. Silky Serum Base: 29.9%

Total: 100%

• Note: This example increases Vitamin B3, adds Caffeine, Hyaluronic Acid, and D-Panthenol, slightly reduces water and base, and corrects the total percentage.*

Important Considerations

• Always refer to the supplier's recommended usage rates and mixing instructions for each specific ingredient.
• Perform a patch test on a small area of skin before applying the finished product around the eyes.
• Stability testing is recommended for any new formulation.

Your original formula is a good foundation, and with a few targeted additions for puffiness and enhanced hydration, you can create a comprehensive eye serum to address all your concerns!

Hope this feedback is helpful!
