Ingredient review
Tobacco Plant Peptide Complex
INCI: Nicotiana Benthamiana Hexapeptide-40 Sh-Polypeptide-76
A novel peptide complex from tobacco plants that may support collagen and skin firmness, but research is still early.
In plain English
This ingredient is a mix of small protein fragments (peptides) made from a special tobacco plant. Peptides are like tiny signals that tell your skin cells to produce more collagen and repair themselves. Because it's new, we don't have a lot of human studies yet, but early lab work suggests it could help reduce fine lines and improve skin texture.

Quick decision guide
Useful, but context matters
Tobacco Plant Peptide Complex 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 Tobacco Plant Peptide Complex.
- 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 blend of two peptides (hexapeptide-40 and sh-polypeptide-76) produced using biotechnology from the Nicotiana benthamiana plant, a relative of tobacco. It's designed to mimic natural signaling peptides in the skin.
How it works
These peptides are thought to bind to receptors on skin cells, triggering them to produce more collagen and elastin. This can help strengthen the skin's structure, reduce the appearance of wrinkles, and improve firmness over time.
Pros
Novel anti-aging potential
Early research suggests it may stimulate collagen, which can help reduce wrinkles and improve skin firmness over time.
Biotech production
Made using plant-based biotechnology, which can be more sustainable and consistent than animal-derived peptides.
Cons and cautions
Limited evidence
Most data comes from lab or animal studies; human trials are scarce, so effectiveness in real-world skincare is not fully proven.
Potential allergen
Derived from a tobacco plant, it may cause reactions in people with plant allergies, though this is uncommon.
Best for
- People looking for anti-aging benefits
- Those interested in novel biotech ingredients
Use caution if
- Anyone with known allergies to tobacco or Nicotiana species
- Pregnant or nursing individuals (due to lack of safety data)
Usage tips
Safety summary
Current safety data is limited but suggests low irritation and comedogenic risk. As with any new ingredient, patch testing is recommended, especially for sensitive skin.
Research notes
Evidence is emerging from in vitro and preliminary studies. No large-scale human trials have been published, so efficacy claims should be viewed with caution.
Common label clues
- Typical concentration
- 0.1% to 1% in leave-on products
- Regulatory status
- Generally recognized as safe for cosmetic use in the EU and US, but not specifically approved by the FDA for any medical claim.
- Common uses
- Anti-aging serums, Eye creams, Moisturizers
- Environmental note
- Produced via plant-based biotechnology, which can have a lower environmental footprint than synthetic chemical processes.
Good to know
- This ingredient is not the same as nicotine and does not have addictive properties.
- It is often combined with other peptides or antioxidants for enhanced effects.
