Ingredient review
Oligopeptide-100 Amide
INCI: Oligopeptide-100 Amide
A synthetic peptide amide that signals skin to produce more collagen, helping reduce fine lines and improve firmness with low irritation risk.
In plain English
Oligopeptide-100 Amide is a lab-made protein fragment (a peptide) that has been modified with an amide group to make it more stable and effective. In skincare, it acts like a messenger, telling your skin cells to produce more collagen and elastin, which are the building blocks that keep skin firm and smooth. Over time, this can help soften the look of fine lines and wrinkles, and improve overall skin texture. Because it's a peptide, it's generally very gentle and well-tolerated, even by sensitive skin.

Quick decision guide
Useful, but context matters
Oligopeptide-100 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 Oligopeptide-100 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
moderateThere is useful support, but formula details and claim strength still matter.
What it is
Oligopeptide-100 Amide is a synthetic peptide, meaning it is a short chain of amino acids (the building blocks of proteins) created in a laboratory. The 'amide' part refers to a chemical modification that helps the peptide stay stable in a formula and better penetrate the skin's outer layer.
How it works
When applied to the skin, Oligopeptide-100 Amide is thought to mimic natural signaling molecules that trigger fibroblasts (skin cells) to ramp up production of collagen and elastin. This helps reinforce the skin's structural support network, leading to a firmer, more resilient appearance over weeks of consistent use.
Pros
Gentle anti-aging support
Unlike stronger actives like retinoids, Oligopeptide-100 Amide is very unlikely to cause redness, peeling, or irritation, making it a safe choice for daily use on sensitive skin.
Stable and easy to formulate
The amide modification improves the peptide's stability in water-based formulas, so it stays effective longer on the shelf and in your skincare routine.
Cons and cautions
Gradual results
You won't see overnight changes. It typically takes 4 to 8 weeks of consistent use to notice visible improvements in fine lines and firmness.
Less research than classic peptides
While the mechanism is sound, there are fewer published clinical studies specifically on Oligopeptide-100 Amide compared to older, more widely studied peptides like Matrixyl.
Best for
- Anyone looking to soften fine lines and improve skin firmness without irritation
- People with sensitive or reactive skin who want anti-aging benefits
Use caution if
- Those seeking immediate or dramatic wrinkle reduction (peptides work gradually)
Usage tips
Safety summary
Oligopeptide-100 Amide is considered safe for cosmetic use with a low risk of irritation or allergic reaction. It is not known to be comedogenic (pore-clogging) and is well-tolerated across skin types. As with any new ingredient, a patch test is recommended for those with very sensitive skin.
Research notes
Peptides in general have moderate evidence supporting their ability to stimulate collagen synthesis in vitro and in small human trials. Specific data on Oligopeptide-100 Amide is limited, but its mechanism is consistent with well-studied signaling peptides. More independent clinical research would strengthen the evidence base.
Common label clues
- Typical concentration
- Typically used at 0.1% to 2% in leave-on formulations
- Regulatory status
- Approved as a cosmetic ingredient in the EU, US, and other major markets. It is not classified as a drug and cannot claim to treat or cure skin conditions.
- Common uses
- Anti-aging serums, Firming creams, Eye treatments
- Environmental note
- As a synthetic peptide, it is produced in controlled lab conditions, which generally has a lower environmental footprint than harvesting plant-derived alternatives.
Good to know
- Peptides like Oligopeptide-100 Amide work well with hyaluronic acid and niacinamide for added hydration and barrier support.
- It is not a sunscreen and does not protect against UV damage, which is a primary cause of collagen breakdown.
