Salix Alba Extract

Plant extract with proven skin-soothing, antioxidant benefits

Contains beneficial compounds of salicin, polyphenols, and flavonoids

Also goes by the name willow bark

Often touted as a natural alternative to salicylic acid, however research shows the exfoliation association is questionable

Salix alba extract, also known as willow bark extract, is a plant extract with proven skin-soothing benefits.

Some skin care brands tout this ingredient as a natural alternative to the salicylic acid (BHA) exfoliants. This association comes from the fact that willow bark contains salicin, a substance that when taken orally is converted by the digestive process to salicylic acid.

It’s important to clarify the process of converting willow bark’s salicin into salicylic acid requires the presence of enzymes and other biological complexities. Further, salicin, much like salicylic acid, is stable only under acidic conditions. The likelihood that Salix alba (willow) bark extract in the tiny amount used in cosmetics can mimic the effect of salicylic acid is questionable at best.

That said, there are still benefits to Salix alba (willow) bark extract in skin care. Studies indicate the salicin content can offer general anti-aging properties for skin and its other beneficial compounds (including polyphenols and flavonoids) contribute to its antioxidant effects.

In skin care, this ingredient is typically used in amounts of 0.5–1%, with a maximum recommended concentration of 10%. Amounts below 0.5% may be used in concert with other soothing ingredients, depending on formulary goals.
