Ingredient review
Shikimoyl Pentapeptide-5
INCI: Shikimoyl Pentapeptide-5
A synthetic peptide that may help firm skin and soften wrinkles, with low irritation potential.
In plain English
This is a lab-made peptide (a small protein fragment) that is attached to shikimic acid, a plant-derived compound. In skincare, it is used to signal skin cells to produce more collagen and elastin, which can help make skin feel firmer and look smoother over time. It is generally well-tolerated and unlikely to clog pores.

Quick decision guide
Useful, but context matters
Shikimoyl Pentapeptide-5 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 Shikimoyl Pentapeptide-5.
- 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
Shikimoyl Pentapeptide-5 is a synthetic peptide conjugate. It combines a pentapeptide (a chain of five amino acids) with shikimic acid, a compound found in plants like star anise. This combination is designed to enhance the peptide's stability and ability to penetrate the skin.
How it works
Once applied, the peptide is thought to mimic natural signaling molecules that tell skin cells to boost collagen and elastin production. This can help improve skin firmness and reduce the depth of fine lines and wrinkles over weeks of consistent use. The shikimic acid component may also offer mild antioxidant benefits.
Pros
Gentle on skin
Low irritation and comedogenic risk make it suitable for sensitive and acne-prone skin types.
Supports collagen
Designed to encourage collagen production, which can help maintain skin structure and reduce sagging over time.
Cons and cautions
Slow results
Visible improvements in firmness and wrinkles typically take several weeks to months of daily use.
Less researched
Compared to classic peptides like Matrixyl, there are fewer published human studies on this specific conjugate.
Best for
- People looking for a gentle anti-aging ingredient
- Those with fine lines or loss of firmness
- Sensitive skin types seeking a low-irritation peptide
Use caution if
- Those allergic to any peptide or shikimic acid source
- Anyone expecting instant results
Usage tips
Safety summary
Shikimoyl Pentapeptide-5 is considered safe for topical cosmetic use. It has low irritation and comedogenic potential. As with any new ingredient, a patch test is recommended for those with very sensitive skin.
Research notes
Evidence is largely based on in vitro studies and some small-scale human trials showing improved skin firmness and reduced wrinkle depth. More extensive peer-reviewed human studies are needed to confirm long-term efficacy.
Common label clues
- Typical concentration
- 0.1% to 1%
- Regulatory status
- Generally recognized as a safe cosmetic ingredient when used as directed. Not classified as a drug.
- Common uses
- Anti-aging serums, Firming creams, Eye treatments
- Environmental note
- Synthetic production reduces reliance on plant harvesting for shikimic acid, but the environmental impact of peptide synthesis is not well documented.
Good to know
- Shikimic acid is also a precursor in the synthesis of the antiviral drug oseltamivir (Tamiflu), but this has no relevance to skincare use.
- Peptides are fragile; avoid using with very low pH (highly acidic) products in the same routine.
