Clogging risk

low

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

Evidence level

What it is

A water- or solvent-based extract made from the leaves of Prostanthera incisa, a plant native to Australia known for its aromatic, mint-like scent.

How it works

The extract contains natural compounds like polyphenols and flavonoids that can neutralize free radicals (unstable molecules that damage skin cells) and may reduce signs of irritation. It works gently on the skin's surface, offering antioxidant protection without stripping or sensitizing.

Pros

Gentle antioxidant

Helps protect skin from free radical damage without causing irritation, making it suitable for daily use in serums and moisturizers.

Soothing potential

May calm minor redness or sensitivity, offering a mild anti-inflammatory effect for reactive skin types.

Cons and cautions

Limited research

Most evidence comes from lab studies; human clinical trials are scarce, so the exact benefits for skin are not fully proven.

Potential allergen

As a botanical extract, it can cause allergic reactions in rare cases, especially in those with plant allergies.

Best for

  • People with normal to sensitive skin looking for gentle antioxidant support
  • Those who prefer natural, plant-based skincare ingredients

Use caution if

  • Individuals with known allergies to mint-family plants (Lamiaceae) should patch test first

Usage tips

Look for this extract in serums or lightweight moisturizers for daytime antioxidant protection.
Always patch test a new product containing this ingredient on your inner arm before full-face use.
