Salicylic Acid occurs naturally in the bark of the Black Willow tree (Salix nigra). The role of bark is to protect the tree by regulating temperature, moisture, nutrients and attacks by environmental stressors.
Your skin has a similar function — it's the body's largest organ and it serves as a protective barrier. That's why Burt's Bees went straight to the bark to find a natural source of salicylic acid. Who needs synthetics when you can harness the wonders of nature?
