In the form most often used in topical products, salicylates work primarily as rubefacients. Rubefacients are compounds that work by counter-irritation, causing skin irritation, local vasodilatation, and a feeling of warmth when applied to the skin surrounding soft tissue injuries. With this surface stimulation, an analgesic effect is achieved by masking the perception of pain. This is in contrast to topical NSAIDs (such as topical diclofenac), which act by inhibiting cyclooxygenase enzymes responsible for development of inflammatory processes.
