Oligopeptide-113

INCI: Oligopeptide-113

A synthetic peptide that may help reduce fine lines and improve skin firmness by signaling collagen production, but research is still emerging.

In plain English

Oligopeptide-113 is a short chain of amino acids (the building blocks of proteins) made in a lab. When applied to skin, it acts like a messenger, telling skin cells to produce more collagen and elastin. This can help plump the skin, smooth fine lines, and improve firmness over time. It's a gentle ingredient, unlikely to cause irritation, and works best in leave-on products like serums.

Quick decision guide

Useful, but context matters

Oligopeptide-113 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.

  1. Step 1Start with the score, then check the irritation and clogging risk before judging Oligopeptide-113.
  2. Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
  3. 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

low

Less likely to sting, burn, or bother most users, though sensitive skin can still react.

Clogging risk

low

Less likely to feel heavy or contribute to clogged pores for most skin types.

Evidence level

moderate

There is useful support, but formula details and claim strength still matter.

What it is

A synthetic peptide composed of a specific sequence of amino acids, designed to mimic natural signaling molecules in the skin that trigger collagen synthesis.

How it works

Oligopeptide-113 binds to receptors on skin cells (fibroblasts) and signals them to increase production of collagen and other structural proteins. This helps reinforce the skin's support matrix, leading to firmer, smoother skin with continued use.

Pros

Gentle on skin

Oligopeptide-113 has a low irritation risk, making it suitable for sensitive skin types that may react to stronger anti-aging ingredients like retinol.

Targeted collagen support

It specifically signals collagen production, which can help improve skin firmness and reduce fine lines over weeks to months of consistent use.

Cons and cautions

Subtle results

Peptides like Oligopeptide-113 typically produce gradual, modest improvements rather than dramatic changes, so patience is needed.

Limited independent research

Most evidence comes from ingredient suppliers or small studies; large-scale, peer-reviewed human trials are still scarce.

Best for

  • People looking for a gentle anti-aging ingredient
  • Those with fine lines or loss of firmness who want a non-irritating option

Use caution if

  • Anyone with a known allergy to synthetic peptides (rare)
  • Those expecting immediate or dramatic results

Usage tips

Apply a peptide serum to clean, damp skin before heavier creams to maximize absorption.
Store peptide products away from direct sunlight and heat to maintain stability.
Use consistently for at least 8–12 weeks to see visible improvements.

Safety summary

Oligopeptide-113 is considered safe for topical use in cosmetics at typical concentrations. It has low irritation and allergy potential, though patch testing is recommended for very sensitive individuals.

Research notes

Research on Oligopeptide-113 is primarily from ingredient manufacturers and in vitro studies. While it shows promise for collagen stimulation, more independent clinical trials are needed to confirm its efficacy in humans.

Common label clues

Typical concentration
0.001% to 0.1%
Regulatory status
Approved as a cosmetic ingredient in the EU, US, and other major markets. Not classified as a drug or medicine.
Common uses
Anti-aging serums, Firming creams, Eye treatments
Environmental note
Synthetic peptides are produced in controlled lab settings, which reduces environmental impact compared to animal-derived ingredients, but their biodegradability is not well studied.

Good to know

  • Peptides are often listed near the end of ingredient lists because they are effective at very low concentrations.
  • Oligopeptide-113 is water-soluble and works well in gel or serum formulations.
