# Nonapeptide-1

## Quick Summary

Nonapeptide-1 is the peptide ingredient callout in RoC Multi Correxion Revive + Glow Daily Serum. In SKB copy, it belongs in cosmetic language around tone, radiance, and more even-looking complexion support, not medical pigmentation treatment.

## What It Is

Nonapeptide-1 is a peptide listed in the official INCI for RoC Multi Correxion Revive + Glow Daily Serum. The same product page describes the formula as using a patented blend of Vitamin C, Nonapeptide, and antioxidants. Because the public page uses the broader Nonapeptide callout while the ingredient list specifies Nonapeptide-1, this entity connects the consumer-facing ingredient name to the INCI name.

## Mechanism

For this product context, Nonapeptide-1 should be described as a cosmetic peptide used in tone, radiance, and more even-looking complexion positioning. The strongest source here is the official product page, so this entity avoids medical pigment claims and avoids treating the ingredient as a standalone prescription-style active. Its role is best explained beside the vitamin C derivative, glycerin/propanediol humectants, and antioxidant-positioned botanicals in the overall serum formula.
