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."]},{"heading":"Mechanism","paragraphs":["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."]}],"ranked_product":{"title":"RoC Multi Correxion Revive + Glow Daily Serum","url":"https://skinknowledgebase.com/products/roc-multi-correxion-revive-glow-daily-serum"},"ranked_products":[{"title":"RoC Multi Correxion Revive + Glow Daily Serum","url":"https://skinknowledgebase.com/products/roc-multi-correxion-revive-glow-daily-serum"}]}
