- One of the most significant studies directly examined copper peptides for acne scars. Researchers compared dermaroller treatment alone versus dermaroller combined with copper peptide compound. Patients with facial acne scars were divided into two groups and followed for 16 weeks, with assessments every three weeks using the Goodman and Baron scoring system, a standardized method for evaluating acne scar severity.
- The findings were nuanced and instructive.
- Both groups showed significant improvement in superficial and moderately deep scars. Both groups showed improved skin texture and reduction in post-acne pigmentation. The copper peptide group showed faster initial improvements in the early weeks. However, from week six onward, the differences between groups narrowed, with both treatments producing similar long-term results.
- The study concluded that copper peptides may drive faster initial improvement, but microneedling alone achieves comparable outcomes over extended treatment periods. This suggests copper peptides accelerate the healing process rather than fundamentally changing the outcome.
