Ingredient review
Dipeptide-41 Nicotinate
INCI: DIPEPTIDE-41 NICOTINATE
A synthetic peptide-niacin hybrid that may help firm skin and reduce fine lines, but research is still limited compared to well-studied peptides.
In plain English
Dipeptide-41 Nicotinate is a lab-made ingredient that links a small protein fragment (a dipeptide) with a form of vitamin B3 (nicotinate). In skincare, it's added to products like anti-aging serums and creams with the goal of encouraging firmer, smoother-looking skin. Think of it as a targeted signal that tells skin cells to produce more collagen and repair themselves, while the vitamin B3 part helps calm and brighten. Because it's relatively new, there's less independent research on it than on older peptides like Matrixyl or copper peptides.

Quick decision guide
Useful, but context matters
Dipeptide-41 Nicotinate 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 Dipeptide-41 Nicotinate.
- 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 compound where a dipeptide (two amino acids linked together) is chemically bonded to nicotinic acid (a form of vitamin B3). This combination is designed to deliver both peptide signaling and niacin benefits in one molecule.
How it works
The dipeptide portion is thought to mimic natural collagen fragments, signaling skin cells to boost collagen production and improve firmness. The nicotinate component may help improve circulation and support skin barrier function, while also providing antioxidant-like effects. Together, they aim to reduce the appearance of fine lines and wrinkles over time.
Pros
Dual-action molecule
Combines peptide signaling with vitamin B3 activity, potentially offering both firming and soothing benefits in one ingredient.
Low irritation profile
Generally well-tolerated even for sensitive skin types, with a low risk of redness or stinging when used at typical concentrations.
Cons and cautions
Limited research backing
Fewer peer-reviewed studies exist compared to classic anti-aging peptides, so its long-term efficacy is less established.
Higher price point
Synthetic peptide ingredients are more expensive to produce, which can make products containing them pricier for consumers.
Best for
- People looking for anti-aging benefits with a gentle ingredient
- Those who want to try a newer peptide technology alongside proven ingredients
Use caution if
- Individuals with known sensitivity to peptides or niacin should patch test first
Usage tips
Safety summary
Dipeptide-41 Nicotinate is considered safe for topical use in cosmetics at typical concentrations. It has low irritation and comedogenic potential, but as with any new ingredient, patch testing is recommended for sensitive individuals.
Research notes
Research on Dipeptide-41 Nicotinate is still emerging. Most evidence comes from manufacturer studies and small trials. While peptide technology in general is well-supported for anti-aging, this specific compound lacks the extensive independent clinical data of more established peptides.
Common label clues
- Typical concentration
- Typically used at 0.1% to 2% in leave-on products
- Regulatory status
- Approved for cosmetic use in the EU, US, and other major markets as a skin conditioning agent. No specific restrictions beyond general cosmetic safety regulations.
- Common uses
- Anti-aging serums, Firming creams, Eye treatments
- Environmental note
- Synthetic peptides are produced through chemical synthesis, which has a lower environmental footprint than animal-derived ingredients but requires energy and solvents.
Good to know
- Dipeptide-41 Nicotinate is often found in high-end anti-aging serums and eye creams.
- It is not the same as niacinamide (another form of vitamin B3), though both offer skin-soothing benefits.
