Functions
Antioxidant

Colorant

Neutralizes Free Radicals
Traditional Use
This is the CAS number for salicylic acid. First isolated from willow bark in the 1800s, salicylic acid became a cornerstone of acne treatment in the 20th century after its exfoliating and antibacterial properties were scientifically validated.
