Salicylic acid is a stable compound that does not require refrigeration for preservation. In fact, storing salicylic acid in the refrigerator may not provide any additional benefits and could potentially lead to some drawbacks.

Refrigeration may cause salicylic acid to solidify or crystallize, which can alter its texture and make it less effective when applied to the skin. Additionally, temperature fluctuations that occur when removing the product from the refrigerator and exposing it to room temperature repeatedly can promote bacterial growth, potentially compromising the product's integrity.

To ensure the longevity and efficacy of salicylic acid, it is generally recommended to store it in a cool, dry place away from direct sunlight. This will help maintain its stability and extend its shelf life. Always check the product's packaging or consult the manufacturer's instructions for any specific storage recommendations.
