Ingredient review
Mevalonoyl Pentapeptide-37
INCI: MEVALONOYL PENTAPEPTIDE-37
A lab-made peptide that signals skin to act firmer and smoother, with good tolerability for most skin types.
In plain English
Mevalonoyl Pentapeptide-37 is a small protein fragment made in a lab. When applied to skin, it acts like a messenger, telling skin cells to behave more youthfully. It is not a vitamin or plant extract, but a targeted ingredient often found in anti-aging products. Because it is synthetic, it is consistent and less likely to cause allergic reactions than some natural extracts.

Quick decision guide
Useful, but context matters
Mevalonoyl Pentapeptide-37 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 Mevalonoyl Pentapeptide-37.
- 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) modified with a mevalonoyl group to improve stability and skin penetration. It belongs to a class of ingredients called matrikines, which mimic natural peptide signals in the skin.
How it works
It binds to specific receptors on fibroblasts (the cells that produce collagen and elastin) and encourages them to increase production of these structural proteins. Over time, this can help improve skin firmness and reduce the depth of fine lines and wrinkles.
Pros
Targeted anti-aging action
Specifically signals skin cells to boost collagen and elastin, addressing firmness and wrinkles at a cellular level.
Low irritation risk
Synthetic peptides are generally non-irritating and non-comedogenic, making them suitable for sensitive and acne-prone skin.
Cons and cautions
Slow, gradual results
Unlike fillers or retinoids, peptide effects build up over weeks to months, requiring patience and consistent application.
Variable effectiveness
The final result depends heavily on the product's overall formula, concentration, and how well the peptide penetrates the skin.
Best for
- Adults looking to address early signs of aging like fine lines and loss of firmness
- People with sensitive skin who want a gentle anti-aging option
Use caution if
- Those with known allergies to synthetic peptides (rare)
- Pregnant or nursing individuals should consult a doctor before using any new active ingredient
Usage tips
Safety summary
Mevalonoyl Pentapeptide-37 is considered safe for cosmetic use at typical concentrations. It has low irritation and allergy potential. No significant safety concerns have been reported in published literature or regulatory reviews.
Research notes
Clinical studies on similar pentapeptides show improvements in skin firmness and wrinkle depth after 8-12 weeks of use. Direct studies on Mevalonoyl Pentapeptide-37 are limited, but the mechanism is well-supported by peptide science.
Common label clues
- Typical concentration
- Typically used at 0.1% to 1% in leave-on products
- Regulatory status
- Approved as a cosmetic ingredient in the EU, US, and other major markets. Not classified as a drug.
- Common uses
- Anti-aging serums, Firming creams, Eye treatments
- Environmental note
- Synthetic peptides are produced via chemical synthesis, which has a lower environmental footprint than harvesting plant or animal sources.
Good to know
- Peptides are fragile; avoid products with very low pH (below 4) that may break them down.
- Mevalonoyl Pentapeptide-37 is often combined with other peptides for a broader anti-aging effect.
