Ingredient review
Methyl Salicylate
INCI: Methyl Salicylate
Methyl salicylate can soothe minor muscle aches and provide a cooling-warming sensation, but it may irritate sensitive skin and should be used cautiously around the face.
In plain English
Methyl salicylate is a compound found naturally in wintergreen and birch bark. In skincare, it's used to create a feeling of warmth or coolness on the skin, which can help soothe minor muscle tension. It also has mild exfoliating properties because it's related to salicylic acid, but it's much gentler. However, it can be irritating if used in high amounts or on broken skin, so it's best reserved for body products rather than facial care.

What it is
Methyl salicylate is an ester of salicylic acid and methanol, naturally occurring in wintergreen leaves and birch bark. It is a colorless to pale yellow liquid with a characteristic minty aroma.
How it works
When applied to the skin, methyl salicylate is absorbed and converted to salicylic acid, which has mild anti-inflammatory and exfoliating effects. It also stimulates sensory receptors, producing a warming or cooling sensation that can distract from minor aches.
