Long ago, therapists found that soaking willow bark in hot water can reduce people’s headache, toothache and fever. In 1828, French pharmacist Henri lerux and Italian chemist Rafael Piria extracted the effective component from willow bark and named it salicin with the Latin name saixalba of white willow. Piria obtained salicylic acid by decomposing the substance. This kind of antipyretic and pain relieving drug – salicylic acid was finally extracted from the bark of white willow. In the early stage, salicylic acid was used to soften hard skin or dissolve cutin. Aspirin, a common anti-inflammatory drug, was sodium acetylsalicylate, a derivative of salicylic acid.
In 1997, Dr. Kligman published his research results in the American Journal of Dermatology and surgery. Using 30% high concentration salicylic acid as a chemical skin changing agent can achieve the same effect as 70% fruit acid.
