What can the ingredient lists tell you?
The current COSRX 6 Peptide Skin Booster Serum list names six peptide ingredients. The Ordinary Multi-Peptide + HA Serum list names seven peptide ingredients. That is a count of names on the manufacturers’ published ingredient lists, not a measure of peptide concentration, skin delivery, or which finished product works better.

Why ingredient order cannot rank results
An ingredient list can identify disclosed ingredients, but it does not give the exact concentration of every peptide or show how much reaches a target in skin. A count of peptide names is not a potency score. The former article inferred that the products’ listed positions proved concentrations below one percent, then used that inference to recommend one product for specific skin types. The official pages do not substantiate those concentration estimates, that skin-type ranking, or a head-to-head result.

Try the BMI Calculator →What a product comparison can establish
On the current published lists, The Ordinary names one more peptide ingredient than COSRX. COSRX and The Ordinary also include different non-peptide ingredients and use different product formats. Those are observable formula differences. They do not establish which serum produces better wrinkle, firmness, hydration, or tolerance outcomes.
FAQ
Which serum lists more peptide ingredients?
The Ordinary’s current Multi-Peptide + HA list names seven peptide ingredients; COSRX’s 6 Peptide Skin Booster list names six. This is a label count only.
Does a higher ingredient-list position prove a higher concentration?
The product pages do not disclose the percentage of each peptide. List order alone does not provide an exact concentration for each named peptide.
Is one finished serum proven to work better than the other?
The linked manufacturer pages do not report a head-to-head clinical comparison of these two finished products, so their ingredient lists do not establish a winner.
