Suggested Formula: Vitamin B3, Hyaluronic Acid & Peptide Serum

Here is a suggested formula based on your request for a serum containing Vitamin B3 4%, Hyaluronic Acid, peptides, and distilled water, with a focus on beneficial ingredients:

Ingredients:

• Extreme-B3™ (Vitamin B3, Niacinamide): 4%
• 4D Hyaluronic Acid: 3%
• Copper Peptide (GHK-Cu): 1%
• Pep®-Synthe6 (Palmitoyl Tripeptide-38): 2%
• Phenoxyethanol (Extra Pure): 1% (Preservative)
• Distilled Water: 89% (Balance to 100%)

Notes on Ingredients:

• Extreme-B3™ (Vitamin B3): At 4%, this helps reduce wrinkles, improve skin tone, increase moisture by stimulating ceramides, and can help with oil control. This is a high-purity grade suitable for sensitive skin.
• 4D Hyaluronic Acid: This provides multi-layer hydration due to its blend of different molecular sizes, including small molecules that penetrate deeper and larger molecules that hydrate the surface and provide a gel texture. Using 3% provides good hydration for normal to dry skin.
• Copper Peptide (GHK-Cu): Known for its skin repair and anti-aging properties, helping to reduce the appearance of scars and wrinkles.
• Pep®-Synthe6 (Palmitoyl Tripeptide-38): A peptide specifically designed to help reduce the appearance of wrinkles.
• Phenoxyethanol (Extra Pure): A safe and effective preservative necessary for water-based formulas to prevent microbial growth. Using 1% is within the recommended range.
• Distilled Water: The base of the serum.

Mixing Instructions:

1. In a clean container, combine the Distilled Water, Extreme-B3™, and 4D Hyaluronic Acid. Mix gently until all powders are dissolved and the mixture is homogeneous.
2. Add Phenoxyethanol (Extra Pure) and mix well.
3. Ensure the temperature of the mixture is below 40°C. Add the Copper Peptide (GHK-Cu) and Pep®-Synthe6 (Palmitoyl Tripeptide-38). Mix gently to incorporate.
4. Check the pH of the final serum. The optimal pH range for the stability and effectiveness of these ingredients (especially peptides and Vitamin B3) is typically between 4.5 and 7.0. Adjust if necessary.
5. Pour the finished serum into a clean bottle.

This formula provides a potent serum targeting hydration, anti-aging, and overall skin health. Always perform a small patch test before applying to a larger area of skin.
