Ingredient review
Tetrapeptide-44 Nicotinate
INCI: Tetrapeptide-44 Nicotinate
A lab-made peptide fused with a form of vitamin B3, aimed at supporting skin structure, but with limited independent research.
In plain English
Tetrapeptide-44 nicotinate is a synthetic ingredient that combines a small protein fragment (a tetrapeptide) with a modified version of niacin (vitamin B3). In skincare, it is used to help support the skin's natural support network, potentially improving firmness and reducing the look of fine lines. Because it is a newer ingredient, most evidence comes from the manufacturer's studies rather than broad independent research.

Quick decision guide
Useful, but context matters
Tetrapeptide-44 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 Tetrapeptide-44 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 peptide (a chain of four amino acids) chemically linked to nicotinic acid, a form of vitamin B3. This combination is designed to deliver both peptide signaling and niacin-related benefits in one molecule.
How it works
Peptides act as signaling molecules that can encourage skin cells to produce more collagen and other structural proteins. The nicotinate portion may support circulation and skin barrier function. Together, the ingredient aims to reinforce the skin's support structure, leading to a firmer, more resilient appearance over time.
Pros
Dual-action molecule
Combines a peptide signal with a niacin derivative, potentially offering both collagen support and barrier benefits in one ingredient.
Low irritation potential
Generally well-tolerated, making it suitable for most skin types, including sensitive skin, when used at recommended concentrations.
Cons and cautions
Limited independent research
Most available data comes from the ingredient manufacturer, so independent peer-reviewed studies are scarce, making it hard to verify claims.
Newer ingredient
As a relatively recent addition to skincare, long-term safety and efficacy data are not as robust as for more established peptides or niacinamide.
Best for
- People looking for anti-aging support with a gentle ingredient
- Those interested in peptide-based skincare who want a combined peptide-niacin option
Use caution if
- Individuals with known allergies to any peptide or niacin compounds
- Anyone seeking ingredients with extensive independent clinical backing
Usage tips
Safety summary
Tetrapeptide-44 nicotinate is considered safe for topical use at typical cosmetic concentrations. Patch testing is recommended for those with very sensitive skin or known peptide allergies.
Research notes
Evidence is primarily from manufacturer-sponsored studies showing improved skin firmness and reduced wrinkle depth. Independent peer-reviewed research is lacking, so the ingredient's efficacy is supported but not yet broadly validated.
Common label clues
- Typical concentration
- 0.1% to 1%
- Regulatory status
- Approved for cosmetic use in most regions including the EU and US, with no specific restrictions at typical use levels.
- Common uses
- Anti-aging serums, Firming creams, Eye treatments
- Environmental note
- Synthetic peptides are produced in labs, which reduces the need for natural resource extraction, but the manufacturing process may involve chemical solvents.
Good to know
- This ingredient is often found in higher-end anti-aging products due to its specialized synthesis.
- It is not the same as niacinamide, though both are forms of vitamin B3.
