Hansaplast Corns Dressing softens corns thanks to its active ingredient, salicylic acid. This ingredient, located in the center of the foam ring, works by softening the structure that supports the callus cells. The callous skin and the intercellular substance that holds its layers together soften, which leads to an increase in the hydration of the area. The result is that corn can also be peeled easily. Available in easy-to-apply plasters, these dressings offer coverage and relief even to the parts of the foot that are difficult to cover and also provide long-lasting protection thanks to their highly reliable adhesives.
