How to Use Nonapeptide-1
Complete guide to Nonapeptide-1 dosing, administration, timing, and protocol recommendations.
Quick Overview
Nonapeptide-1, sold as Melanostatine 5, is a nine-amino-acid synthetic peptide built to block alpha-MSH, the hormone that tells pigment cells to make melanin. It goes into brightening and dark-spot products as a gentler alternative to harsh lighteners. It is a cosmetic ingredient, not an FDA-approved drug, and there is no independent peer-reviewed clinical trial of it on its own.
Dosing Guidelines
Common Dose
Low percentage in a brightening serum
Frequency
Once or twice daily
Dose Range
Not standardized
Note: Results for any brightening ingredient depend heavily on daily sun protection. Hyperpigmentation that is new, changing, or uneven in color should be looked at by a dermatologist before you try to fade it.
Administration Method
Topical (serums, creams)
Best Time to Take
Morning (under sunscreen) and/or evening
No timing data exist. Morning use under sunscreen makes sense since UV is the main trigger for the pigment signal it blocks.
Protocol Duration
Brightening claims are usually judged over 8 to 12 weeks; ongoing use
Possible Side Effects
Not everyone experiences these. Individual responses vary.
- •Generally well tolerated
- •Mild irritation (uncommon)
- •No systemic effects expected from topical use
- •Brightening products do nothing if you skip sunscreen
