Ingredient review
Myristoyl Hexapeptide-14
INCI: MYRISTOYL HEXAPEPTIDE-14
A synthetic peptide that may help improve skin firmness and reduce fine lines, with low irritation potential.
In plain English
Myristoyl Hexapeptide-14 is a lab-made peptide (a small chain of amino acids) that is added to skincare products to help support the skin's structure. It works by signaling skin cells to produce more collagen and other supportive proteins, which can make the skin feel firmer and look smoother over time. Because it is used in very small amounts, it is generally gentle and unlikely to cause irritation.

Quick decision guide
Useful, but context matters
Myristoyl Hexapeptide-14 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 Hexapeptide-14.
- 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 peptide consisting of six amino acids linked to a myristic acid chain, designed to penetrate the skin and mimic natural signaling molecules that encourage collagen production.
How it works
When applied topically, the myristoyl group helps the peptide absorb into the skin. Once inside, it signals fibroblasts (cells that produce collagen) to increase collagen synthesis, which can improve skin firmness and reduce the appearance of fine lines and wrinkles.
Pros
Supports collagen production
Encourages the skin to produce more collagen, which can help maintain firmness and reduce sagging over time.
Low irritation potential
Used at very low concentrations, making it suitable for most skin types, including sensitive skin.
Cons and cautions
Gradual results
Visible improvements in skin firmness and wrinkles typically take weeks to months of consistent use.
Variable effectiveness
The actual benefit depends heavily on the product formulation and the concentration used, which is often not disclosed.
Best for
- Individuals looking to reduce signs of aging
- Those with normal to dry skin seeking extra firmness
Use caution if
- People with known allergies to peptides (rare)
- Those seeking immediate results
Usage tips
Safety summary
Myristoyl Hexapeptide-14 is considered safe for topical use in cosmetics. It has a low irritation and comedogenic risk, and no significant safety concerns have been reported in available literature.
Research notes
Peptides like Myristoyl Hexapeptide-14 are supported by in vitro and some clinical studies showing collagen stimulation and anti-aging effects. However, independent peer-reviewed research on this specific peptide is limited, and most evidence comes from ingredient suppliers.
Common label clues
- Typical concentration
- 0.001% to 0.1%
- Regulatory status
- Approved for cosmetic use in the US, EU, and other major markets as a skin conditioning agent.
- Common uses
- Anti-aging serums, Firming creams, Eye treatments
- Environmental note
- Synthetic peptides are produced in laboratories, which reduces the need for natural resource extraction, but their production involves chemical synthesis and purification steps.
Good to know
- Peptides are fragile and can be degraded by certain preservatives or pH extremes
- Look for products with peptides listed near the middle or top of the ingredient list for higher concentration
