Science
Mechanism of Action
Forms a lightweight occlusive barrier that reduces transepidermal water loss while serving as an effective solvent for lipophilic actives and UV filters. The salicylate ester structure allows for slow hydrolysis on skin, potentially releasing minimal salicylic acid for mild anti-inflammatory and smoothing effects.
