Ingredient review
SH-Oligopeptide-73 Amide
INCI: SH-Oligopeptide-73 Amide Trifluoroacetate
A lab-made peptide that may help firm skin and reduce fine lines, but research is still early and results vary.
In plain English
This is a small protein fragment made in a lab. When applied to skin, it's thought to signal cells to produce more collagen, which can help skin look firmer and smoother over time. It's a gentle ingredient, unlikely to cause irritation, but it's not a quick fix—results take weeks of consistent use.

Quick decision guide
Useful, but context matters
SH-Oligopeptide-73 Amide 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-73 Amide.
- 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
emergingThe ingredient may be promising, but claims should be treated more cautiously.
What it is
SH-Oligopeptide-73 Amide Trifluoroacetate is a synthetic peptide (a short chain of amino acids) modified with an amide group and stabilized with trifluoroacetate. It is designed to mimic naturally occurring signaling peptides that communicate with skin cells.
How it works
In a cosmetic product, this peptide is believed to bind to receptors on skin cells and trigger a cascade that boosts collagen and elastin production. The amide modification helps it penetrate the skin's outer layer more effectively, while the trifluoroacetate salt improves stability in the formula.
Pros
Gentle on skin
Low irritation and comedogenic risk make it suitable for sensitive skin types, including those prone to redness or breakouts.
Supports collagen signaling
The peptide structure is designed to mimic natural signals that encourage collagen production, potentially improving skin firmness over time.
Cons and cautions
Slow, subtle results
You won't see changes overnight; noticeable improvements typically take 8–12 weeks of daily use, and effects are modest.
Limited research backing
Most evidence comes from lab studies or small trials; large-scale human studies are lacking, so the true efficacy is not fully established.
Best for
- Adults looking for a gentle anti-aging option
- Those with sensitive skin who cannot tolerate stronger actives like retinol
Use caution if
- Anyone seeking immediate or dramatic results
- People with very tight budgets, as peptide products tend to be pricier
Usage tips
Safety summary
SH-Oligopeptide-73 Amide Trifluoroacetate is considered safe for cosmetic use at typical concentrations. It has low irritation and comedogenic potential, and no significant safety concerns have been reported in available literature.
Research notes
Evidence is primarily from in vitro studies and small clinical trials. While the mechanism is plausible, large-scale human studies are needed to confirm anti-aging benefits. The ingredient is part of a broader class of peptides with some supporting data for collagen stimulation.
Common label clues
- Typical concentration
- 0.001% to 0.1%
- Regulatory status
- Approved as a cosmetic ingredient in the US and EU; not classified as a drug. No specific restrictions at typical use levels.
- Common uses
- Anti-aging serums, Firming creams, Eye treatments
- Environmental note
- Synthetic peptides are produced in controlled lab settings, reducing environmental impact compared to animal-derived ingredients. However, the manufacturing process involves chemical synthesis and may have a moderate carbon footprint.
Good to know
- The trifluoroacetate salt is a common stabilizer for peptides and is safe at the low levels used in cosmetics.
- Peptides work best as part of a complete skincare routine that includes sunscreen and moisturizer.
