What it is

An extract derived from the leaves of the maidenhair fern (Adiantum pedatum), a plant traditionally used in herbal remedies. The extract contains various bioactive compounds like flavonoids and phenolic acids.

How it works

It works primarily by providing antioxidant compounds that neutralize free radicals, and by offering anti-inflammatory effects that can help calm redness or irritation. It may also support the skin's moisture barrier by conditioning the outer layer.

Pros

Gentle on skin

Low irritation and comedogenic risk makes it suitable for sensitive and acne-prone skin types.

Antioxidant support

Helps protect skin from daily environmental damage like pollution and UV exposure.

Cons and cautions

Limited research

Most evidence comes from lab or traditional use, not large-scale human trials on cosmetic benefits.

Potential allergen

Though rare, fern allergies exist and could cause a reaction in sensitive individuals.

Best for

  • People with sensitive or easily irritated skin
  • Those looking for gentle, plant-based antioxidant ingredients

Use caution if

  • Individuals with known allergies to ferns or related plants

Usage tips

Look for it in serums or moisturizers formulated for sensitive skin.
