INCI: Benzylsulfonylseryl-glycine Amidinobenzamide Acetate

A synthetic peptide that may help reduce under-eye bags and improve skin firmness, but research is still emerging.

beautyskincareactive

In plain English

This is a lab-made ingredient that mimics certain proteins in your skin. It's designed to help tighten and firm the skin, especially around the eyes, by encouraging the skin to drain excess fluid and support its structure. Think of it as a gentle, non-invasive way to help with puffiness and sagging.

Quick decision guide

Useful, but context matters

Benzylsulfonylseryl-glycine Amidinobenzamide Acetate 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 Benzylsulfonylseryl-glycine Amidinobenzamide Acetate.
  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

emerging

The ingredient may be promising, but claims should be treated more cautiously.

What it is

A synthetic peptide derivative, specifically a combination of amino acids (seryl-glycine) with a benzylsulfonyl group and an amidinobenzamide acetate. It is designed to target skin firmness and decongestion.

How it works

It is believed to work by interacting with the skin's extracellular matrix, potentially stimulating collagen production and improving lymphatic drainage. This can help reduce fluid buildup (puffiness) and support the skin's structural integrity, leading to a firmer appearance.

Pros

Targets puffiness

Specifically designed to help reduce fluid retention under the eyes, making it a good option for morning puffiness.

Low irritation potential

Generally considered gentle and non-irritating, suitable for the delicate eye area.

Cons and cautions

Limited evidence

Most research is from the manufacturer or small studies; independent large-scale human trials are lacking.

Can be pricey

As a specialized synthetic peptide, it often appears in higher-end products, which may be a barrier for some budgets.

Best for

  • People with under-eye puffiness
  • Those looking for a gentle firming ingredient

Use caution if

  • Those with very sensitive skin (patch test recommended)
  • Pregnant or nursing individuals (consult doctor)

Usage tips

Apply to clean, damp skin for better absorption.
Use consistently for at least 4-6 weeks to see potential results.
Store products containing this ingredient in a cool, dark place to maintain stability.

Safety summary

Considered safe for topical use at typical concentrations. Low irritation and comedogenic risk. As with any new ingredient, a patch test is recommended, especially for sensitive skin.

Research notes

Evidence is primarily from in vitro studies and small clinical trials sponsored by ingredient manufacturers. More independent research is needed to confirm efficacy and long-term safety.

Common label clues

Typical concentration
0.1% to 1%
Regulatory status
Approved for cosmetic use in the EU, US, and other major markets. No specific restrictions beyond general cosmetic safety regulations.
Common uses
Eye creams, Serums, Firming lotions
Environmental note
Synthetic production reduces reliance on natural resources, but the environmental impact of its manufacturing is not well-documented.

Good to know

  • Often found in eye creams and targeted serums.
  • May be combined with caffeine or other peptides for enhanced effects.
  • Not a substitute for medical treatments for chronic puffiness or sagging.
