Ingredient review
Galloyl SH-Pentapeptide-5
INCI: Galloyl SH-Pentapeptide-5
A synthetic peptide that may help firm skin and soften fine lines, but research is still emerging and it works best as part of a broader anti-aging routine.
In plain English
This is a lab-made ingredient that combines a small protein fragment (a peptide) with a compound from plants (gallic acid). In skincare, it's meant to signal skin cells to produce more collagen and elastin, which can help skin feel firmer and look smoother over time. Think of it as a gentle messenger that tells your skin to act a bit younger.

Quick decision guide
Useful, but context matters
Galloyl SH-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 Galloyl SH-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
Galloyl SH-Pentapeptide-5 is a synthetic peptide engineered by attaching a gallic acid molecule to a pentapeptide (a chain of five amino acids). The gallic acid part is a type of antioxidant found in plants like gallnuts and tea, while the peptide portion is designed to mimic natural collagen fragments that stimulate skin repair.
How it works
When applied to the skin, the peptide portion is thought to bind to receptors on fibroblasts (the cells that make collagen), encouraging them to produce more collagen and elastin. The gallic acid group may provide additional antioxidant protection, helping to shield the skin from environmental damage that accelerates aging. Over time, this can lead to improved skin firmness and a reduction in fine lines.
Pros
Dual-action peptide
Combines collagen-stimulating peptide with antioxidant gallic acid, offering two benefits in one ingredient.
Low irritation potential
Generally well-tolerated even at effective concentrations, making it suitable for many skin types.
Cons and cautions
Gradual results
Visible improvements in firmness and wrinkles typically take weeks to months of consistent use.
Limited research
Most evidence comes from lab studies or small trials; large-scale human studies are lacking.
Best for
- Adults looking for a gentle anti-aging ingredient to support skin firmness
- Those with aging concerns who want a peptide option that also offers antioxidant benefits
Use caution if
- Individuals with known allergies to synthetic peptides or gallic acid derivatives
- Those with very sensitive skin who react to multiple active ingredients
Usage tips
Safety summary
Galloyl SH-Pentapeptide-5 is considered safe for topical cosmetic use. It has low irritation and comedogenic potential, but as with any new ingredient, a patch test is recommended for sensitive individuals.
Research notes
Research on this specific peptide is limited but promising. Studies on similar galloyl-peptide conjugates suggest antioxidant and collagen-boosting effects, but more human clinical trials are needed to confirm efficacy.
Common label clues
- Typical concentration
- 0.001% to 0.1%
- Regulatory status
- Generally recognized as safe for cosmetic use in the EU, US, and other major markets when used within recommended concentrations.
- Common uses
- Anti-aging serums, Firming creams, Eye treatments
- Environmental note
- Synthetically produced, so it does not rely on plant harvesting; however, its environmental impact depends on manufacturing processes.
Good to know
- This ingredient is often found in high-end anti-aging serums and eye creams.
- It is stable in formulations with a pH around 5–6, which is typical for skin-friendly products.
