Effective positive component, nourishes and accelerates cleaning.

A plant extract containing salicin, a substance that changes the digestive process into salicylic acid (beta hydroxykyselin).

The process of conversion of salicin into willow cortex into salicylic acid requires the presence of enzymes and is complex. Like salicylic acid, salicylic acid is only stable under acidic conditions.

The probability that willow bark in small quantities used in cosmetics can mimic the effect of salicylic acid is at best questionable and in all probability impossible.

However, the bark of the willow may have soothing effects on the skin.
