What these differences mean
Different names do not tell us which serum works better.
The selected peptide names differ. The complete formulas may still share other ingredients. Open an ingredient explanation to see its intended use and the kind of evidence behind it.
Check the whole product for precautions.
An ingredient name cannot predict your skin’s reaction. Cosmetics can cause irritation or allergic reactions. Check the complete label and follow the product directions.
FDA: cosmetic reactions and precautionsOne ingredient study does not rank these serums.
Studies of an ingredient, supplier descriptions and brand claims answer different questions. We have not recorded an independent head-to-head study of these two serums. Lower cost per mL does not establish better results.

What does “exact name” mean?
We match the written ingredient name, ignoring letter case. We do not merge differently named chemical forms. The same name does not establish the same concentration, delivery, or effect.
Selected label peptides, not the complete INCI list. Other peptides and non-peptide ingredients may be omitted. See the manufacturer for the full formula. Palmitoyl Tripeptide-38 is identified in the brand’s explanation of Matrixyl Synthe’6; its displayed list uses that system name. Selected label ingredients, not the complete INCI list.

What the brand tells us
Timeless states 2% Matrixyl Synthe’6. This is a named-system disclosure, not a verified pure-peptide concentration.
1% copper peptides appears in the product name; individual concentrations for the selected remaining peptides are not recorded.
A disclosed blend percentage does not automatically establish every ingredient’s concentration. These are brand disclosures, not independent laboratory measurements.
