Ingredient review
Nicotinoyl SH-Nonapeptide-3
INCI: NICOTINOYL SH-NONAPEPTIDE-3
A synthetic peptide that may help improve skin firmness and reduce fine lines, with low irritation risk.
In plain English
This is a lab-made peptide (a small chain of amino acids) that is attached to a form of vitamin B3 (niacin). Peptides are like tiny signals that tell skin cells to produce more collagen and elastin, which are the proteins that keep skin plump and firm. The added vitamin B3 part may help boost the peptide's stability and effectiveness. In skincare, it is used to target signs of aging like wrinkles and loss of firmness.

Quick decision guide
Useful, but context matters
Nicotinoyl SH-Nonapeptide-3 is generally a lower-concern ingredient when the full formula suits your skin.
Plain-English read
Treat this as a practical screening step before you compare products that contain this ingredient.
- Step 1Start with the score, then check the irritation and clogging risk before judging Nicotinoyl SH-Nonapeptide-3.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
- Step 3If a product stings, breaks you out, or worsens irritation, judge the finished formula and stop using it even if the ingredient scores well.
Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
moderateThere is useful support, but formula details and claim strength still matter.
What it is
A synthetic peptide consisting of nine amino acids (nonapeptide) with a nicotinoyl (vitamin B3 derivative) group attached. It is designed to mimic natural signaling peptides that stimulate collagen production.
How it works
When applied topically, the peptide is thought to bind to receptors on skin cells and signal them to increase production of collagen and other structural proteins. The nicotinoyl group may enhance penetration and stability, allowing the peptide to work more effectively in the deeper layers of the skin.
Pros
Targeted anti-aging support
Specifically designed to signal collagen production, which can help improve skin firmness and reduce fine lines over time.
Low irritation risk
Synthetic peptides are generally well-tolerated, making this ingredient suitable for many skin types, including sensitive skin.
Cons and cautions
Limited independent research
Most evidence comes from manufacturer studies; independent peer-reviewed research on this exact peptide is sparse, so efficacy claims should be taken with caution.
Results require patience
Peptides work slowly, and visible improvements in firmness or wrinkles may take weeks to months of consistent use.
Best for
- Adults looking to address early signs of aging
- Those with normal to dry skin seeking extra firmness support
Use caution if
- Individuals with known allergies to peptides or niacinamide
- Those with very sensitive or reactive skin should patch test first
Usage tips
Safety summary
Nicotinoyl SH-Nonapeptide-3 is considered safe for topical use at typical concentrations. It has low irritation and comedogenic potential. As with any new ingredient, a patch test is recommended for those with sensitive skin.
Research notes
Evidence is primarily from manufacturer-sponsored studies showing improved skin firmness and reduced wrinkle depth. Independent peer-reviewed studies on this specific peptide are limited, but the mechanism is supported by broader research on signaling peptides in skincare.
Common label clues
- Typical concentration
- 0.1% to 1%
- Regulatory status
- Approved for cosmetic use in the EU, US, and other major markets. Not classified as a drug ingredient.
- Common uses
- Anti-aging serums, Eye creams, Facial moisturizers
- Environmental note
- Synthetic peptides are produced in labs, which reduces the need for animal-derived or plant-based raw materials, but the manufacturing process has an energy footprint.
Good to know
- This peptide is often found in higher-end anti-aging serums and eye creams.
- It can be combined with other anti-aging ingredients like vitamin C or retinol, but apply in the correct order (water-based before oil-based).
