What is it?
The effect of salicylic acid can be found in the upper layers of the skin. The acid acts by loosening the intercellular structure, which holds together the horny cells in the corn. This leads to an increased hydration, which causes the corn to swell, and soften (a process called keratolytic action) – thus, the mechanical removal of the skin cells is facilitated. The plaster should be applied to dry, clean skin and worn for two days. Results should show after four days. For more info, click here.
