Nicotiana Benthamiana Sh-Polypeptide-7

INCI: Nicotiana Benthamiana Sh-Polypeptide-7

A plant-based peptide that may help support collagen and skin firmness, but research is still early.

beautyskincarepeptide

In plain English

This is a peptide made from a tobacco plant (Nicotiana benthamiana). Peptides are short chains of amino acids that act like messengers in the skin, telling it to produce more collagen and repair itself. Because it comes from a plant, it's a biotech ingredient—grown in a lab using plant cells, not harvested from fields. It's a newer ingredient, so while early studies look promising, we don't have decades of data yet.

Quick decision guide

Useful, but context matters

Nicotiana Benthamiana Sh-Polypeptide-7 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.

  1. Step 1Start with the score, then check the irritation and clogging risk before judging Nicotiana Benthamiana Sh-Polypeptide-7.
  2. Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
  3. 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

low

Less likely to sting, burn, or bother most users, though sensitive skin can still react.

Clogging risk

low

Less likely to feel heavy or contribute to clogged pores for most skin types.

Evidence level

emerging

The ingredient may be promising, but claims should be treated more cautiously.

What it is

A synthetic peptide produced via biotechnology using Nicotiana benthamiana plant cells. It is a signaling peptide designed to mimic natural skin-repair processes.

How it works

It is thought to bind to skin cell receptors and stimulate collagen production, helping to reduce fine lines and improve skin firmness over time. It may also support the skin's natural repair mechanisms.

Pros

Plant-based peptide

Derived from Nicotiana benthamiana via biotechnology, making it a sustainable and vegan-friendly alternative to animal-derived peptides.

Potential anti-aging support

Early research suggests it may stimulate collagen production, which can help reduce fine lines and improve skin firmness over time.

Cons and cautions

Limited human research

Most evidence comes from lab or early-stage studies; large-scale human trials are lacking, so effectiveness is not yet fully proven.

Newer ingredient

As a relatively new cosmetic ingredient, there is less long-term safety and efficacy data compared to well-established peptides like Matrixyl.

Best for

  • People looking for anti-aging benefits from a plant-based peptide
  • Those with sensitive skin who tolerate peptides well

Use caution if

  • Anyone with a known allergy to tobacco or Nicotiana species (rare)
  • Those seeking proven, extensively studied anti-aging ingredients

Usage tips

Use in a serum or moisturizer applied to clean, damp skin for better absorption.
Pair with other anti-aging ingredients like vitamin C or niacinamide, but avoid using with strong exfoliants at the same time to reduce irritation risk.

Safety summary

Generally considered safe for topical use at typical concentrations. No significant irritation or sensitization reported in available studies, but long-term data is limited.

Research notes

Early in vitro and small-scale human studies suggest potential for collagen stimulation and anti-aging benefits. More robust clinical trials are needed to confirm efficacy and safety.

Common label clues

Typical concentration
0.1% to 1% in leave-on products
Regulatory status
Approved for use in cosmetics in the EU, US, and other major markets. No specific restrictions beyond general cosmetic safety requirements.
Common uses
Anti-aging serums, Firming creams, Eye treatments
Environmental note
Produced via plant cell culture biotechnology, which reduces land use and pesticide use compared to traditional farming.

Good to know

  • Nicotiana benthamiana is a close relative of tobacco but is not used for smoking—it's grown in labs for research and biotechnology.
  • This ingredient is often found in high-end anti-aging products due to its novel, plant-based origin.
