Nonapeptide-1 Brightening Serum
Also known as Nonapeptide-1, Melanostatine
INCI name · Nonapeptide-1
A brightening-focused peptide serum built around Nonapeptide-1 — for a more radiant look and to soften the appearance of dull, uneven areas. For external cosmetic use only.
Where our renewal serum chases dewy glow, this one is about evenness. Nonapeptide-1 — a nine-amino-acid peptide, hence 'nona' — is the active our brightening serum is built around, chosen for the look of a more radiant, even-toned complexion.
It's the tone specialist of the collection. As always, everything here is cosmetic and appearance-only; there are no treatment claims and no invented figures.
A nonapeptide, named plainly
'Nona' means nine — Nonapeptide-1 is a peptide built from nine amino acids, and that's exactly how it appears on an ingredient panel. It's a water-soluble cosmetic active that formulates into a light, clean serum.
Its whole reason for being on the shelf is tone: it's the peptide reached for when the appearance goal is even, radiant-looking skin rather than firmness or expression lines.
The even-tone angle
Dullness and unevenness are as much about how light meets skin as anything. This serum is used to help skin look even-toned and luminous and to soften the appearance of dull, uneven areas — a brightness that reads as evenness, not shine.
It's a natural partner to the Oligopeptide-1 renewal serum: one leans dewy-fresh, the other leans even-tone, and together they cover the brightening brief.
Wearing a brightening serum well
Brightening routines love daylight discipline. If you use this in the morning, finish with sunscreen as your final step — an even-tone look is best protected by good sun habits. It layers cleanly under moisturizer and SPF.
How to use it
External use only. Smooth a few drops over clean skin morning and/or evening before moisturizer; in daytime, always follow with sunscreen as the final step. Patch-test on the inner arm before first use and discontinue if irritation occurs. Store cool and out of direct sun.
