The 100 points
We split Antioxidant Peptide Serum into 3 standout parts. Each bar shows what the build earns.
A signaling peptide; a related palmitoyl pentapeptide improved photoaged skin in a 12-week study.
A copper complex; the copper peptide literature is largely from makers.
Antioxidants without published levels.
No close retail equivalent: we credit at most 50% of these points.
Optional
49 / 100. We have not found a shelf product that closes more of the gap yet.
65 is our ceiling. Palmitoyl tripeptide-38 has no close retail equivalent, so we cap it at 75% credit. Copper lysinate/prolinate has no close retail equivalent, so we cap it at 75% credit. Resveratrol ferment and phenyl t-butylnitrone has no close retail equivalent, so we cap it at 50% credit.
