Salicylic Acid is a beta hydroxy acid found in many plants but its most well-known source is White Willow or Salix alba from which its name is derived. Salicylic acid is the active metabolite of the drug Aspirin (Acetylsalicylic acid) a well-known pain-relieving medication. Salicylic Acid is obtained by synthesis.
Topically, Salicylic acid is most commonly found in products used to combat acne and other skin conditions such as dandruff. It acts as a comedolytic and bacteriostatic agent meaning it stimulates the shedding off dead skin cells, unclogs pores, and inhibits the growth of potentially acne-causing bacteria. It can make the skin smoother and reduce fine lines by increasing fibrillin and collagen.
Salicylic acid is very poorly water-soluble and will need to be dissolved in a suitable solvent such as ethanol or propylene glycol before incorporating it into your formulations. The use of surfactants can also be useful.
