Serum Formulation for Wrinkle Reduction

Regarding your serum formulation for reducing forehead and smile lines using Argireline 10%, Pep®-Coll 5%, Homeostatine™ 5%, and Aloe Vera Extract 3%:

1. Mixing and Thickening:

   • Yes, you can mix all the ingredients in distilled water. However, as the staff mentioned, this will result in a liquid consistency.
   • To achieve a thicker, gel-like texture, you will need to add a thickener such as Pro Polymer.
   • You can start by adding Pro Polymer at a concentration of 0.5% and increase it gradually until you reach your desired viscosity.

2. pH Testing:

   • Based on the ingredients in your formula, pH testing is not strictly necessary.
   • The formulation is expected to have a slightly acidic pH (around 5-6), which is well-suited for facial skin.

Ingredient Functions:

• Argireline (Acetyl Hexapeptide-8) is a peptide known for its ability to help reduce the appearance of wrinkles caused by muscle movement, particularly on the forehead and around the eyes.
• Pep®-Coll (Palmitoyl tripeptide-5) is a peptide designed to stimulate the skin's natural collagen production, helping to reduce wrinkles.
• Aloe Vera Extract provides skin conditioning, helps reduce irritation, and moisturizes the skin.
