Scholl Corn Removal Plasters use a unique formula to remove corns from feet. Corns, that occur on toes as a result of excessive pressure from footwear, can be a constant source of irritation and an unnecessary stress in your day. The Scholl disk system means that the Salicylclic acid, which helps to break down hardened skin and remove excess skin cells, is only applied to the infected area, ensuring the surrounded skin is protected. The soft cushioning pad relieves pain and pressure and the adhesive is dermatologically tested.
