Ingredient review
Nicotinoyl Dipeptide-22
INCI: Nicotinoyl Dipeptide-22
A synthetic peptide that may help improve skin firmness and reduce fine lines, but human data is still limited.
In plain English
Nicotinoyl Dipeptide-22 is a lab-made peptide (a small chain of amino acids) that is designed to signal skin cells to produce more collagen and elastin, the proteins that keep skin plump and firm. It is often added to anti-aging products to help reduce the look of wrinkles and improve skin texture over time.

Quick decision guide
Useful, but context matters
Nicotinoyl Dipeptide-22 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 Dipeptide-22.
- 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 dipeptide (two amino acids linked together) modified with a nicotinoyl group (a form of vitamin B3) to enhance its stability and skin benefits.
How it works
It is thought to mimic natural peptide signals in the skin, encouraging fibroblasts to produce more collagen and elastin. This can help strengthen the skin's support structure, leading to firmer, smoother skin with regular use.
Pros
Gentle anti-aging option
Nicotinoyl Dipeptide-22 is considered very gentle on the skin, making it suitable for those with sensitive skin who want anti-aging benefits without irritation.
Targets collagen production
It works by signaling skin cells to produce more collagen, which can help improve skin firmness and reduce the appearance of fine lines over time.
Cons and cautions
Limited human evidence
Most of the research on this peptide comes from lab studies or small trials, so the strength of evidence for its effectiveness in real-world use is still emerging.
Slow results
Like many peptides, it requires consistent use over several weeks to months before visible improvements in skin firmness or wrinkles appear.
Best for
- Adults looking to improve skin firmness and reduce early signs of aging
- Those with sensitive skin who cannot tolerate stronger anti-aging ingredients like retinol
Use caution if
- Anyone with a known allergy to synthetic peptides (rare)
- Pregnant or nursing individuals should consult a doctor before using new ingredients
Usage tips
Safety summary
Nicotinoyl Dipeptide-22 is considered safe for topical use in cosmetics at typical concentrations. It has low irritation and comedogenic potential, making it suitable for most skin types. However, long-term safety data is limited, and individuals with very sensitive skin should patch test first.
Research notes
Evidence for Nicotinoyl Dipeptide-22 is primarily from in vitro (lab) studies and small-scale human trials suggesting it can stimulate collagen synthesis. Larger, independent clinical studies are needed to confirm its efficacy and compare it to other anti-aging peptides.
Common label clues
- Typical concentration
- Typically used at 0.1% to 2% in leave-on products
- Regulatory status
- Approved for use in cosmetics in the EU, US, and many other regions. No specific restrictions beyond general cosmetic safety regulations.
- Common uses
- Anti-aging serums, Eye creams, Firming lotions
- Environmental note
- As a synthetic peptide, its production is lab-based and does not directly rely on plant or animal harvesting, but the environmental impact depends on the manufacturing process.
Good to know
- Peptides are generally more effective when combined with other anti-aging ingredients like antioxidants (vitamin C, vitamin E) or hyaluronic acid.
- Nicotinoyl Dipeptide-22 is not the same as niacinamide (vitamin B3), though it contains a nicotinoyl group.
