Ingredient review
SH-Pentapeptide-7
INCI: SH-Pentapeptide-7
A well-studied synthetic peptide that helps reduce wrinkles by boosting collagen and calming inflammation, with a strong safety profile.
In plain English
SH-Pentapeptide-7 is a small protein fragment made in a lab. When applied to skin, it acts like a messenger telling skin cells to make more collagen, which helps firm skin and soften lines. It also has anti-inflammatory properties, which can help calm redness or irritation. It's a gentle ingredient suitable for most skin types, including sensitive skin.

Quick decision guide
Easy yes for most routines
SH-Pentapeptide-7 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 SH-Pentapeptide-7.
- 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
SH-Pentapeptide-7 is a synthetic peptide composed of five amino acids linked to a palmitic acid chain. This structure helps it penetrate the skin and mimic natural signaling molecules that stimulate collagen production.
How it works
Once absorbed, SH-Pentapeptide-7 binds to receptors on fibroblasts (skin cells that produce collagen). This triggers a cascade that increases collagen and elastin synthesis, improving skin firmness and reducing wrinkle depth. Its anti-inflammatory action comes from inhibiting certain inflammatory mediators, which can help soothe skin.
Pros
Clinically studied anti-aging
Multiple studies show SH-Pentapeptide-7 can reduce wrinkle depth and improve skin firmness with regular use over 8-12 weeks.
Gentle on skin
Unlike retinol or acids, this peptide rarely causes irritation, peeling, or dryness, making it suitable for sensitive skin types.
Cons and cautions
Slow visible results
You won't see dramatic changes overnight; noticeable improvements typically take 2-3 months of daily application.
Higher cost products
Peptide-based products tend to be more expensive than simpler moisturizers, though a little goes a long way.
Best for
- Anyone looking to reduce signs of aging
- People with sensitive or reactive skin who cannot tolerate retinol
- Those wanting a gentle collagen-boosting ingredient
Use caution if
- Individuals with known peptide allergies (rare)
Usage tips
Safety summary
SH-Pentapeptide-7 has a strong safety record with low irritation and allergy potential. The Cosmetic Ingredient Review (CIR) panel has deemed similar peptides safe for cosmetic use. No significant systemic absorption or toxicity concerns.
Research notes
Clinical studies show statistically significant reductions in wrinkle depth and improvements in skin firmness after 8-12 weeks. Anti-inflammatory effects are supported by in vitro research. More long-term human studies would strengthen the evidence base.
Common label clues
- Typical concentration
- 0.0001% to 0.01%
- Regulatory status
- Approved as a cosmetic ingredient in the US, EU, and other major markets. Not classified as a drug; claims must stay within cosmetic boundaries.
- Common uses
- Anti-aging serums, Eye creams, Moisturizers
- Environmental note
- Synthetically produced, so no direct impact on natural peptide sources. Manufacturing processes vary by supplier; some use green chemistry practices.
Good to know
- Often paired with other peptides like Palmitoyl Tripeptide-1 in products labeled 'Matrixyl 3000'.
- Can be used alongside hyaluronic acid and niacinamide for enhanced benefits.
