The 100 points
We split Professional-C Peptide Complex into 5 standout parts. Each bar shows what the build earns.
The signature pair: cytokinins shown to improve spots, wrinkles and hydration in a split-face trial.
No close retail equivalent: we credit at most 40% of these points.
A longer cousin of Argireline aimed at softening expression lines.
A stable vitamin C form for uneven tone and dullness.
Extra antioxidants that back up the vitamin C.
Light hydration and barrier comfort.
Optional
58 / 100. We have not found a shelf product that closes more of the gap yet.
82 is our ceiling. Kinetin and zeatin (plant growth factors) has no close retail equivalent, so we cap it at 40% credit.

One bottle instead of a build. Sorted by match score; scores use the same standouts as above.
Naturium
No close match yet — we show the nearest formulas.
Why it is close. A peptide serum with Argireline plus a copper peptide and antioxidants in a creamy base. It matches the peptide and antioxidant side well. It has no growth factors or vitamin C.
Not an affiliate link.
Geek & Gorgeous
Why it is close. Covers the vitamin C and vitamin E side for about $12. L-ascorbic acid is a stronger but more irritating vitamin C than the oil-soluble form in Obagi. Pair it with a peptide serum for the rest.
Not an affiliate link.
The Ordinary
Why it is close. Covers the peptide half of the formula for under $10. Argireline is the six-amino-acid version of the same peptide family. It has no growth factors or vitamin C, so it is a partial match.
