Benzylcarbamato Cinnamidoisopentyl Dipeptide-38 Amide

INCI: BENZYLCARBAMATO CINNAMIDOISOPENTYL DIPEPTIDE-38 AMIDE

A synthetic peptide that may help soften expression lines and improve skin firmness, but evidence is mostly from ingredient supplier studies.

beautyskincarepeptide

In plain English

This ingredient is a lab-made peptide, which is a short chain of amino acids (the building blocks of proteins). It is designed to mimic natural signaling molecules in the skin, potentially telling skin cells to produce more collagen and relax muscle contractions. In simple terms, it aims to make fine lines and wrinkles less noticeable over time, similar to how some anti-aging peptides work.

Quick decision guide

Useful, but context matters

Benzylcarbamato Cinnamidoisopentyl Dipeptide-38 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.

  1. Step 1Start with the score, then check the irritation and clogging risk before judging Benzylcarbamato Cinnamidoisopentyl Dipeptide-38 Amide.
  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 dipeptide (two amino acids linked together) modified with a benzylcarbamato group and a cinnamidoisopentyl group to improve stability and skin penetration. It is a relatively new cosmetic ingredient developed for anti-aging formulations.

How it works

It is believed to work by mimicking the action of natural neuropeptides that can temporarily relax facial muscles, reducing the appearance of expression lines. Additionally, it may stimulate collagen synthesis by signaling fibroblasts (skin cells that produce collagen) to increase production, leading to firmer, more resilient skin over time.

Pros

Targets expression lines

Designed to relax facial muscles, which may soften crow's feet and forehead lines without the need for injectables.

Low irritation profile

Typically well-tolerated even on sensitive skin, making it a good option for those who cannot use stronger anti-aging ingredients.

Cons and cautions

Limited independent evidence

Most studies are funded by ingredient suppliers, so the real-world effectiveness may be less dramatic than claimed.

Results take time

Peptides generally require consistent use over several weeks to months before visible improvements appear, which may test patience.

Best for

  • Adults looking to soften expression lines around the eyes and forehead
  • Those seeking a gentle anti-aging ingredient without strong actives like retinol

Use caution if

  • Individuals with known allergies to synthetic peptides (rare)

Usage tips

Apply after cleansing and before heavier creams to allow better absorption.
Use consistently twice daily for at least 8-12 weeks to evaluate results.
Pair with a moisturizer containing ceramides or hyaluronic acid to support the skin barrier.

Safety summary

Considered safe for cosmetic use at typical concentrations. Rare reports of mild irritation or allergic reactions. No known systemic toxicity when used topically.

Research notes

Evidence is primarily from in vitro studies and manufacturer-sponsored clinical trials showing improvements in wrinkle depth and skin firmness. Independent peer-reviewed studies are limited, so the evidence level is moderate.

Common label clues

Typical concentration
0.1% to 1%
Regulatory status
Approved for cosmetic use in the EU, US, and other major markets. Not classified as a drug ingredient.
Common uses
Anti-aging serums, Eye creams, Facial moisturizers
Environmental note
Synthetic peptides are produced in laboratories, which reduces the need for natural resource extraction, but their environmental impact depends on manufacturing practices.

Good to know

  • This peptide is often included in high-end anti-aging serums and eye creams.
  • It is compatible with most other skincare ingredients, including vitamin C and retinol, but always patch test when combining new products.
