If used for stimulating collagen production or reducing scars like acne scars, which one performs better? What types of formulations are suitable for each ingredient? Can these two ingredients be used in the same formulation? Thank you in advance.

Quick-Coll® vs. Copper Peptide (GHK-Cu): Key Differences
Both Quick-Coll® (Copper Lysinate/Prolinate) and Copper Peptide (GHK-Cu, Copper Tripeptide-1) are ingredients known for their skin-benefiting properties, particularly related to collagen and tissue repair. However, they have some differences in their composition and described actions:
- Quick-Coll®: This is an amino acid/copper complex (Copper Lysinate/Prolinate). Its description highlights its ability to stimulate the production of collagen (Pro-collagen 1, Collagen 1, and Collagen 3) and elastin, with visible results claimed within 15 days. It focuses broadly on stimulating fibroblasts to improve skin firmness and reduce wrinkles.
- Copper Peptide (GHK-Cu): This is a specific tripeptide (Glycyl-Histidyl-Lysine) complexed with copper. It is well-known for its wound healing and tissue remodeling properties. Its description specifically mentions solving scar problems, including acne scars, reducing wrinkles, and even stimulating hair growth. It is noted as being suitable for use with tools like Derma Rollers to enhance results on scars and wrinkles.
Which is Better for Collagen Stimulation or Scar Reduction?
Based on the product descriptions:
- For Collagen Stimulation: Both are stated to stimulate collagen. Quick-Coll®'s description emphasizes stimulating multiple types of collagen and elastin with a rapid timeframe (15 days).
- For Scar Reduction (like acne scars): Copper Peptide (GHK-Cu) is explicitly mentioned for solving scar problems and acne scars, suggesting it is specifically targeted for this concern.
Choosing which is "better" depends on the primary goal. If the focus is specifically on improving the appearance of scars, GHK-Cu appears to be more directly indicated according to its description. For general collagen and elastin stimulation for firmness and wrinkles, both are presented as effective.
Suitable Formulations
Both ingredients are suitable for use in water-based cosmetic formulations such as gels, serums, lotions, and creams.
- Quick-Coll®: Usage rate is 0.1-2%. The description does not list specific pH restrictions or ingredient incompatibilities.
- Copper Peptide (GHK-Cu): Usage rate is typically 1-3% (for the 1000ppm solution). It requires a pH range of 4.5-7.4 for stability. It should not be used in formulas containing Disodium EDTA, as this can bind the copper and reduce effectiveness.
Can They Be Used Together?
The product descriptions do not provide information on whether Quick-Coll® and Copper Peptide (GHK-Cu) can be used in the same formulation. Both are copper complexes/peptides, and combining different types of these ingredients can sometimes lead to stability issues or reduced efficacy due to potential interactions. Without specific data or guidelines allowing their combination, it is generally advisable to use them in separate formulations or consult with a formulation expert if attempting to combine them.
