Nine signal peptides including a copper peptide and growth-factor-like oligopeptides in a moisturizer base. The variety is the selling point and the caveat: more peptides usually means less of each, and none is disclosed by percentage. An elegant, well-formulated cream; the evidence follows the peptide class, not the count.
Cosmetic peptides are the best-credentialed corner of the anti-aging aisle, which is faint praise worth decoding: two ingredients carry real published support (palmitoyl pentapeptide-4 from a 12-week double-blind facial trial, and copper tripeptide-1/GHK-Cu from decades of wound-healing literature), while the rest run on supplier-sponsored testing. Expect modest fine-line and texture improvement over 8 to 12 weeks, not a procedural result, and read our peptides-in-skincare review for the full class-by-class grading.
Peptide serums layer without conflict alongside retinoids, niacinamide and sunscreen, the better-evidenced backbone of any routine. The one documented caution: avoid applying copper peptides and strong ascorbic-acid (vitamin C) formulas in the same session, since copper can destabilize the vitamin; splitting them between morning and evening resolves it. Judge any peptide product at 12 weeks against a day-zero photo, because the published studies measured at 4 to 12 weeks and supplier claims of overnight change describe hydration, not structure.
