Clarifying Copper Peptide (GHK-Cu) Usage and Concentration
Question
I have a question about the usage of [url=http://www.myskinrecipes.com/shop/%E0%B9%80%E0%B8%9B%E0%B9%8A%E0%B8%9B%E0%B9%84%E0%B8%97%E0%B8%94%E0%B9%8C%E0%B8%A5%E0%B8%94%E0%B8%A3%E0%B8%B4%E0%B9%89%E0%B8%A7%E0%B8%A3%E0%B8%AD%E0%B8%A2/272-copper-peptide-%E0%B8%84%E0%B8%AD%E0%B9%80%E0%B8%9B%E0%B8%AD%E0%B8%A3%E0%B9%8C-%E0%B9%80%E0%B8%9B%E0%B9%8A%E0%B8%9B%E0%B9%84%E0%B8%97%E0%B8%94%E0%B9%8C-ghk-cu.html:k72t549g]Copper Peptide[/url:k72t549g]. The 1000ppm solution sold by the store is equivalent to 1% in solvent, and the store recommends using it at 1-3%. Does this mean that even though it's already dissolved at 1%, it still needs to be further diluted to achieve a final concentration of 1-3%? Can we not apply the 1000ppm solution directly to the skin at 100% concentration? When compared to the powder form, which needs to be dissolved in a solvent to reach the recommended concentration of 0.01-1%, and if dissolved to 1%, can be applied directly, it seems there shouldn't be a difference. Therefore, shouldn't the 1000ppm solution also be applicable directly to the skin? Thank you.
Answer
Clarification on Copper Peptide Usage
Thank you for your question regarding the usage of Copper Peptide.
Let's clarify the concentrations and recommended usage rates for the two forms:
Copper Peptide (GHK-Cu, Copper Tripeptide-1) (1000ppm Solution):
- This product is a solution where the Copper Peptide (GHK-Cu) is already dissolved at a concentration of 1000ppm, which is equivalent to 0.1% (not 1%).
- The recommended usage rate is 1-3%.
- This means you should add 1-3% of this 1000ppm solution into your final cosmetic formulation (like a serum, cream, or gel). You do not need to dilute the 1000ppm solution itself further before adding it to your base formulation.
- Using 1-3% of the 1000ppm solution in your formula will result in a final GHK-Cu concentration of approximately 10-30ppm in your finished product.
Copper Peptide (GHK-Cu Copper Tripeptide-1, 1:1) Powder:
- This is the powder form with a purity of over 98% GHK-Cu.
- The recommended usage rate is 0.01% - 1%.
- This means you should add 0.01% to 1% of this powder into your final cosmetic formulation. The powder needs to be dissolved in a suitable solvent (like distilled water) before adding to the formulation.
- Using 0.01-1% of the powder in your formula will result in a final GHK-Cu concentration of approximately 100-10,000ppm in your finished product.
Can the 1000ppm solution be applied directly?
No, it is not recommended to apply the 1000ppm solution directly to the skin. The recommended usage rate of 1-3% is for incorporating it into a complete cosmetic formulation (serum, cream, etc.). Applying the 1000ppm solution directly would be applying it at its full concentration (0.1% GHK-Cu in solvent), which is not the intended or recommended method of use.
Comparison:
The powder form allows you to achieve a much higher final concentration of GHK-Cu in your finished product (up to 10,000ppm or 1%) compared to using the 1000ppm solution at its recommended rate (resulting in 10-30ppm). The 1000ppm solution is a convenient pre-dissolved form for easier incorporation into formulations at lower final GHK-Cu concentrations.
