Eye Serum Formulation Adjustment

Thank you for sharing your experience with the eye serum formula. It's great to hear that the original formula was effective in reducing puffiness around your mother's eyes.

Regarding Eyeseryl, while the specific trade name might not be available, the key ingredient, Acetyl Tetrapeptide-5, is available as Pep®-Eye (Acetyl Tetrapeptide-5). This ingredient is known for its effectiveness in reducing eye bags and dark circles, similar to Eyeseryl.

Alternatively, as suggested by the staff, REGU®-AGE is another excellent option for addressing dark circles and swelling around the eyes. Its description indicates it helps reduce puffiness and dark circles by improving microcirculation and strengthening the skin.

For the wrinkle concern, since the original combination of Argireline and Matrixyl did not show significant results, the staff's suggestion to switch to other peptides is a good approach. Copper Peptide (GHK-Cu) is highly regarded for its skin repair and anti-aging properties, including reducing wrinkles and improving skin firmness. Repair Activator (available in different bases like BG or WS) is also beneficial for anti-aging as it helps support the skin's natural DNA repair process.

Therefore, to address both puffiness and wrinkles, you could consider the following adjustments:

1. Replace Eyeseryl: Use either Pep®-Eye (Acetyl Tetrapeptide-5) or REGU®-AGE at their recommended usage rates (typically 1-5% for Pep®-Eye, 2-5% for REGU®-AGE). Both are effective for puffiness.
2. Replace Argireline and Matrixyl: Substitute these with Copper Peptide (GHK-Cu) and add Repair Activator.
   • Copper Peptide (GHK-Cu) is available in different concentrations (e.g., 1000ppm, 10000ppm solution, or powder). Choose the appropriate form and usage rate (typically 1-3% for solutions, 0.01-1% for powder) based on the specific product you select.
   • Add Repair Activator (BG or WS) at its recommended usage rate (typically 5-100%, though lower concentrations are often effective). Choose the base (BG or WS) that best suits your formula.

Keep the other ingredients (Water, Cucumber Extract, N-Acetyl Glucosamine, Vitamin B3, Phenoxyethanol, Hyaluronic Acid) as they are compatible and beneficial for an eye serum.

Remember to mix these active ingredients in the final step of your formulation at temperatures below 40°C and ensure the final pH is within the recommended range for the peptides used (e.g., 4.5-7.4 for Copper Peptide, 5.0-8.0 for REGU®-AGE).

By replacing Eyeseryl with Pep®-Eye or REGU®-AGE for puffiness and switching to Copper Peptide and Repair Activator for wrinkles, you may achieve better results for both concerns.
