What it is

A natural extract derived from the bark of the Hesperethusa crenulata tree, a plant native to parts of Asia. It contains various plant compounds, including flavonoids and phenolic acids, which are known for their antioxidant activity.

How it works

The extract is believed to work by donating electrons to neutralize free radicals—unstable molecules that can damage skin cells and accelerate aging. This antioxidant action may help protect the skin from environmental stressors like UV radiation and pollution. It may also have mild soothing properties, though the exact mechanisms are not fully understood.

Pros

Gentle on skin

This extract has a low irritation risk, making it suitable for sensitive skin types that may react to stronger antioxidants.

Natural origin

Derived from a plant source, it appeals to consumers looking for naturally-sourced skincare ingredients.

Cons and cautions

Limited research

There is very little published scientific evidence on the benefits of Hesperethusa crenulata bark extract specifically for skin, so its effectiveness is uncertain.

Unproven efficacy

Compared to well-studied antioxidants like vitamin C, this extract has not been shown to provide reliable or measurable skin benefits in clinical studies.

Best for

  • Anyone looking for a gentle, natural antioxidant ingredient
  • Those with sensitive skin who want to avoid stronger actives

Use caution if

  • Those seeking proven, high-efficacy antioxidant protection

Usage tips
