Effective Usage Percentage for Copper Peptide (1000ppm vs. 10000ppm)

The recommendation of 1-3% for both products can be confusing because their concentrations differ by 10 times. Here is a detailed explanation of the effective dosage and why the recommendations are presented this way.

1. Concentration Comparison

• Copper Peptide (1000ppm): Contains 0.1% pure Copper Tripeptide-1.
• Copper Tripeptide 10x (10000ppm): Contains 1.0% pure Copper Tripeptide-1.

2. Actual Active Content in the Formula

If you follow the 1-3% usage rate:

• Using the 1000ppm version at 1-3%: You get 10-30 ppm of active peptide in your final product. This level is generally considered "maintenance" or "marketing level" (label claim), providing mild antioxidant benefits but may not be sufficient for significant scar repair or deep wrinkle reduction.
• Using the 10000ppm version at 1-3%: You get 100-300 ppm of active peptide. This is the clinically effective range used for skin remodeling, stimulating collagen, and wound healing.

3. Why is 1-3% recommended for both?

The 1-3% recommendation is a standard guideline for liquid active ingredients in cosmetic formulation. It ensures that the additive does not significantly disrupt the stability, viscosity, or texture of the base cream or serum. However, it does not account for the "potency" required for specific results.

4. Recommended Effective Levels (PPM)

For real results, you should aim for the following concentrations of pure GHK-Cu in your final formula:

• General Anti-Aging / Maintenance: 50 - 100 ppm
• Intensive Repair / Deep Wrinkles / Acne Scars: 200 - 500 ppm
• Hair Growth Stimulation: 100 - 500 ppm

Recommendation:

• If you want high efficacy for anti-aging or scar treatment, use Copper Tripeptide 10x (10000ppm) at 2-5% (which provides 200-500 ppm).
• The 1000ppm version is better suited for very light maintenance or for beginners who want to test skin sensitivity.

Important Formulation Rules:

1. pH Balance: The final formula must have a pH between 4.5 - 7.4. If the pH is outside this range, the peptide will break down and lose effectiveness.
2. Avoid Chelating Agents: Do not use Disodium EDTA in the formula, as it will bind with the copper ions and deactivate the peptide.
3. Temperature: Always add Copper Peptide in the final step when the mixture has cooled below 40°C.
4. Avoid Strong Oxidizers: Do not mix with high concentrations of Vitamin C (L-Ascorbic Acid) or Alpha Hydroxy Acids (AHAs) in the same step, as they can destabilize the peptide.
