Ingredient review
Myristoyl Pentapeptide-10
INCI: MYRISTOYL PENTAPEPTIDE-10
A synthetic peptide that may help improve skin firmness and reduce fine lines, with low irritation potential.
In plain English
Myristoyl Pentapeptide-10 is a lab-made protein fragment (peptide) that signals skin cells to produce more collagen and elastin, the building blocks that keep skin plump and firm. Think of it as a tiny messenger that tells your skin to act younger. It's often used in anti-aging products at very low concentrations because a little goes a long way.

Quick decision guide
Useful, but context matters
Myristoyl Pentapeptide-10 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 Myristoyl Pentapeptide-10.
- 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
moderateThere is useful support, but formula details and claim strength still matter.
What it is
A synthetic pentapeptide (a chain of five amino acids) attached to a myristoyl fatty acid chain, which helps it penetrate the skin more easily. It belongs to the family of matrikines—peptides that mimic natural collagen fragments to stimulate repair.
How it works
Once applied, the myristoyl group helps the peptide absorb into the upper layers of skin. There, it binds to receptors on fibroblasts (collagen-making cells) and signals them to ramp up production of collagen and other matrix proteins. Over time, this can lead to firmer, smoother skin with fewer visible lines.
Pros
Gentle anti-aging support
Myristoyl Pentapeptide-10 works by signaling skin cells to produce more collagen, which can help improve firmness and reduce fine lines over time, without the irritation common with stronger actives like retinoids.
Low irritation risk
This peptide is well-tolerated even by sensitive skin types, making it a good option for those who cannot use harsher anti-aging ingredients.
Cons and cautions
Slow, gradual results
Unlike some exfoliating acids or retinoids, peptides take weeks to months of consistent use to show visible improvements, so patience is required.
Higher cost per product
Products containing this peptide tend to be more expensive due to the cost of peptide synthesis, which may not fit every budget.
Best for
- Adults looking to improve skin firmness and reduce fine lines
- Those with sensitive skin seeking a gentle anti-aging option
Use caution if
- Anyone with a known allergy or sensitivity to synthetic peptides (rare)
Usage tips
Safety summary
Myristoyl Pentapeptide-10 is considered safe for cosmetic use at typical concentrations. It has low irritation and comedogenic potential, and no significant safety concerns have been reported in available research.
Research notes
Evidence is primarily from in vitro studies and small human trials showing collagen stimulation and improvement in skin firmness. Larger, long-term human studies are limited, but the ingredient is well-established in cosmetic science.
Common label clues
- Typical concentration
- 0.0001% to 0.1%
- Regulatory status
- Approved as a cosmetic ingredient in the US, EU, and many other regions. Not classified as a drug, so anti-aging claims are limited to cosmetic effects.
- Common uses
- Anti-aging serums, Eye creams, Moisturizers
- Environmental note
- Synthetically produced, so it does not rely on animal or plant harvesting. However, peptide synthesis can involve chemical solvents; overall environmental impact is low due to tiny usage amounts.
Good to know
- Peptides are often paired with antioxidants (like vitamin C) or niacinamide for complementary anti-aging effects.
- Myristoyl Pentapeptide-10 is sometimes listed under the broader name 'Palmitoyl Pentapeptide-10' on ingredient labels.
