In plain English

Think of it as a preservative that keeps the formula effective longer, but it doesn't directly treat your skin.

What it is

A synthetic benzofuranone derivative designed to function as an antioxidant in cosmetic formulations. It is not naturally occurring and is produced through chemical synthesis.

How it works

It works by scavenging free radicals and interrupting the chain reaction of oxidation that can cause oils to become rancid and colors to fade. By stabilizing the formula, it helps maintain the product's intended performance and appearance over time.

Pros

Effective formula stabilizer

Helps keep oils and other sensitive ingredients from spoiling, so your product stays effective longer.

Low irritation risk

At typical use levels, it is considered very gentle on skin and unlikely to cause redness or stinging.

Cons and cautions

Synthetic origin

It is made in a lab, which may be a drawback for those who prefer naturally derived preservatives or antioxidants.

No direct skin benefit

Unlike some antioxidants (like vitamin C or E), this ingredient primarily protects the product, not your skin directly.

Best for

  • Anyone using products with oils or sensitive active ingredients
  • People looking for well-preserved, stable formulas

Use caution if

  • Those seeking exclusively natural or plant-derived ingredients

Usage tips

Look for this ingredient near the end of the ingredient list, as it is used in very small amounts.
Store products containing this ingredient in a cool, dark place to maximize its stabilizing effect.
