Science
Mechanism of Action
Upon topical application, Isocetyl Salicylate undergoes hydrolysis within the skin, releasing Salicylic Acid. Salicylic Acid then acts as a desmolytic agent, precisely disrupting cellular junctions between keratinocytes and dissolving the intercellular cement substance. This action effectively promotes the exfoliation of the stratum corneum, while also reducing its pH, contributing to its well-known keratolytic and comedolytic benefits.

Safety
Safety Profile
The CIR Expert Panel concluded Isocetyl Salicylate is safe in cosmetics at concentrations up to 5% when formulated to be non-irritating and non-sensitizing. While not classified as an active drug ingredient by the FDA, its hydrolysis to Salicylic Acid necessitates considering the potential for increased sun sensitivity and adhering to sun protection guidance. Additionally, SCCS opinions for Salicylic Acid itself, particularly regarding specific product types and use in children, offer relevant considerations.
