Ingredient review
Nicotinoyl Tripeptide-35
INCI: Nicotinoyl Tripeptide-35
A promising synthetic peptide that may help firm skin and soften lines, but human studies are still limited.
In plain English
Nicotinoyl Tripeptide-35 is a lab-made ingredient that links a small protein fragment (a peptide) with a molecule similar to niacinamide (vitamin B3). In skincare, it's added to products like serums and creams with the goal of encouraging the skin to produce more collagen and elastin, which are the proteins that keep skin plump and springy. Because it's a newer ingredient, most of the evidence for its effects comes from lab tests rather than large human studies, so it's best seen as a supportive player in an anti-aging routine rather than a proven miracle worker.

Quick decision guide
Useful, but context matters
Nicotinoyl Tripeptide-35 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 Tripeptide-35.
- 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
emergingThe ingredient may be promising, but claims should be treated more cautiously.
What it is
A synthetic peptide (a short chain of amino acids) that has been chemically attached to a nicotinoyl group, which is related to niacinamide. This combination is designed to boost the peptide's stability and its ability to signal skin cells to produce more collagen.
How it works
Once applied to the skin, the peptide portion is thought to mimic natural collagen fragments, triggering fibroblasts (the cells that make collagen) to ramp up production. The nicotinoyl group may help the peptide penetrate better and also provide mild antioxidant support. Over time, this can lead to firmer, smoother-looking skin.
Pros
Gentle on skin
Nicotinoyl Tripeptide-35 has a low irritation risk, making it suitable for sensitive skin types that may react to stronger anti-aging ingredients.
Supports collagen production
Lab studies suggest it can stimulate collagen synthesis, which may help maintain skin firmness and reduce sagging over time.
Cons and cautions
Limited human evidence
Most research is from lab or animal studies; large-scale human trials are lacking, so the real-world effectiveness is not fully proven.
Subtle effects
Results are gradual and often modest, so it may not satisfy those looking for a noticeable change in skin texture or wrinkles.
Best for
- Anyone looking for a gentle anti-aging ingredient to add to their routine
- People with sensitive skin who want to avoid stronger actives like retinol
Use caution if
- Those seeking fast or dramatic results, as this ingredient works slowly
Usage tips
Safety summary
Nicotinoyl Tripeptide-35 is considered safe for topical use at typical concentrations. It has low irritation and comedogenic potential, and no significant safety concerns have been reported in available literature.
Research notes
Evidence is primarily from in vitro (lab) studies showing collagen stimulation. Human studies are sparse, so the ingredient is best classified as having emerging evidence for anti-aging benefits.
Common label clues
- Typical concentration
- 0.1% to 2%
- Regulatory status
- Approved for cosmetic use in the EU, US, and other major markets as a skin conditioning agent. No specific restrictions apply.
- Common uses
- Anti-aging serums, Firming creams, Eye treatments
- Environmental note
- As a synthetic peptide, it is produced through chemical synthesis, which has a lower environmental footprint compared to some animal-derived ingredients.
Good to know
- This ingredient is often found in combination with other peptides or niacinamide for a synergistic effect.
- It is stable in most formulations and does not require special packaging.
