Ingredient review
SH-Oligopeptide-13
INCI: SH-Oligopeptide-13
A lab-made peptide that may help firm skin and reduce fine lines by encouraging collagen production, though human studies are limited.
In plain English
SH-Oligopeptide-13 is a short chain of amino acids (the building blocks of protein) made in a lab. In skincare, it acts like a tiny messenger that tells your skin cells to produce more collagen and elastin, which are the proteins that keep skin plump and firm. Think of it as a gentle nudge to your skin's natural repair system.

Quick decision guide
Useful, but context matters
SH-Oligopeptide-13 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-Oligopeptide-13.
- 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-Oligopeptide-13 is a synthetic oligopeptide, meaning it is a small chain of amino acids designed to mimic naturally occurring signaling peptides in the skin. It is often used in anti-aging products for its potential to support the skin's structural matrix.
How it works
When applied topically, SH-Oligopeptide-13 is thought to bind to receptors on skin cells (like fibroblasts) and trigger a cascade of signals that increase the production of collagen and other extracellular matrix components. This can help improve skin firmness, elasticity, and reduce the appearance of fine lines over time.
Pros
Gentle on skin
SH-Oligopeptide-13 has a low irritation and comedogenic risk, making it suitable for most skin types, including sensitive skin.
Targeted anti-aging support
It specifically signals collagen production, which can help improve skin firmness and reduce fine lines with regular use.
Cons and cautions
Modest evidence
While promising, human clinical studies on SH-Oligopeptide-13 are limited compared to more established peptides, so results may vary.
Slow to show results
Peptides like this one require consistent application over several weeks to months before visible improvements appear, which may test some users' patience.
Best for
- Adults looking to improve skin firmness and reduce early signs of aging
- Those with normal to dry skin seeking a gentle anti-aging ingredient
Use caution if
- Individuals with known allergies to synthetic peptides (rare)
- Those seeking immediate results, as peptides require consistent use over weeks to months
Usage tips
Safety summary
SH-Oligopeptide-13 is considered safe for topical use in cosmetics at typical concentrations. It has low irritation and comedogenic potential, and no significant safety concerns have been reported in available literature.
Research notes
Research on SH-Oligopeptide-13 is primarily based on in vitro studies showing collagen stimulation. Human studies are limited but suggest potential benefits for skin firmness and wrinkle reduction. More robust clinical trials are needed to confirm efficacy.
Common label clues
- Typical concentration
- 0.001% to 0.1%
- Regulatory status
- Approved for cosmetic use in the US, EU, and other major markets. It is not classified as a drug ingredient.
- Common uses
- Anti-aging serums, Firming creams, Eye treatments
- Environmental note
- As a synthetic peptide, its production has a lower environmental footprint compared to animal-derived ingredients, but it is not biodegradable in large quantities.
Good to know
- Peptides are often more effective when combined with other anti-aging ingredients like antioxidants (e.g., vitamin C) and sunscreen.
- SH-Oligopeptide-13 is water-soluble and typically found in water-based serums.
