Willow Bark Extract (Natural BHA Exfoliant)

What is Willow Bark Extract?

Willow bark extract is a plant extract from the bark of the willow tree (Salix).
It contains salicin, a substance that is converted in the skin to a salicylic acid-like effect. As a result, it acts as a mild, natural form of BHA exfoliation.

Where does Willow Bark Extract come from?

The extract is extracted from the bark of willow trees, especially Salix alba.

 • Cleanses pores and helps loosen sebum and dirt
 • Removes dead skin cells and prevents build-up
 • Reduces impurities and blackheads
 • Improves skin texture and smoothes the skin

How does the salicylic acid action in this extract work?

Willow bark extract does not contain free salicylic acid, but salicin. The skin converts salicin slowly, creating a salicylic acid-like effect.

As a result:
 • dissolves sebum and build-up in the pores
 • loosens dead skin cells
 • it has a purifying effect without the intensity of pure BHA

The effect is similar to salicylic acid, but more gradual and less aggressive.
