What to actually look for
- · INCI position. "Copper tripeptide-1" should appear in the top 8 ingredients for a meaningful effect.
- · Declared concentration (rare). When listed, 0.1 to 1% range is what topical research uses.
- · Air-tight pump packaging. Peptides oxidise quickly in jars.
- · Compatible base. Avoid pairing with vitamin C in the same step (low pH degrades the peptide).
