Ingredient review
Tetrapeptide-67
INCI: Tetrapeptide-67
Tetrapeptide-67 is a promising synthetic peptide that may help improve skin firmness and reduce fine lines, but research is still early and results vary.
In plain English
Tetrapeptide-67 is a tiny protein fragment made of four amino acids. In skincare, it's designed to signal skin cells to produce more collagen and elastin, which are the building blocks that keep skin plump and firm. Think of it as a gentle messenger that tells your skin to act younger. Because it's a synthetic peptide, it's stable in formulas and unlikely to cause irritation.

Quick decision guide
Useful, but context matters
Tetrapeptide-67 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-67.
- 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
Tetrapeptide-67 is a synthetic peptide composed of four specific amino acids. It belongs to a class of ingredients called signal peptides, which are designed to mimic natural peptide fragments that trigger collagen production in the skin.
How it works
When applied topically, Tetrapeptide-67 is thought to penetrate the upper layers of the skin and bind to receptors on fibroblasts (the cells that make collagen). This binding sends a signal to increase collagen and elastin synthesis, which can help improve skin firmness and reduce the appearance of fine lines over time. It also has antioxidant properties that may protect skin from environmental stress.
Pros
Gentle anti-aging support
Tetrapeptide-67 is unlikely to cause irritation or breakouts, making it a safe option for most skin types, including sensitive skin.
Targets collagen production
Unlike surface-level moisturizers, this peptide works by signaling skin cells to produce more collagen, addressing the underlying structure of the skin.
Cons and cautions
Limited research
Most evidence for Tetrapeptide-67 comes from lab studies or small trials. Large-scale human studies are lacking, so its effectiveness is not as well-established as some other peptides.
Subtle results
You may need to use a product containing Tetrapeptide-67 for several months before noticing visible improvements in firmness or wrinkles. It is not a quick fix.
Best for
- Adults looking for a gentle anti-aging ingredient to support skin firmness
- People with sensitive skin who want a low-irritation option for fine lines
Use caution if
- Those seeking immediate or dramatic results (peptides work gradually)
- Individuals with known allergies to synthetic peptides (rare)
Usage tips
Safety summary
Tetrapeptide-67 has a low irritation and comedogenic risk, making it suitable for most skin types. There are no major safety concerns reported in cosmetic use, but as with any new ingredient, a patch test is recommended for those with very sensitive skin.
Research notes
Research on Tetrapeptide-67 is still emerging. Early in vitro studies suggest it can stimulate collagen synthesis, but human clinical data is limited. It is considered a promising but not yet proven anti-aging ingredient.
Common label clues
- Typical concentration
- Typically used at 0.1% to 1% in leave-on formulations
- Regulatory status
- Tetrapeptide-67 is considered a cosmetic ingredient and is not regulated as a drug. It is generally recognized as safe for topical use in cosmetics by major regulatory bodies, but it has not been evaluated by the FDA for medical claims.
- Common uses
- Anti-aging serums, Eye creams, Firming moisturizers
- Environmental note
- As a synthetic peptide, Tetrapeptide-67 is produced in a lab, which reduces the need for animal-derived or plant-based raw materials. Its environmental impact is relatively low compared to some natural extracts that require extensive harvesting.
Good to know
- Tetrapeptide-67 is often combined with other peptides or antioxidants like vitamin C for enhanced anti-aging effects.
- It is stable in water-based formulas and does not require special packaging.
