The Scholl Corn Express Pen is a fast-acting treatment for corns. A common skin complaint- corns are caused by prolonged pressure to the skin of the feet. This pressure causes the skin to thicken and form into an inverted cone- which can press into nerve endings- causing discomfort. The Scholl Corn Express Pen is a unique and highly-effective method of treating corns. In two quick and easy steps- the Corn Express Pen will soften and exfoliate the affected area- reducing painful rubbing. The pen is reusable- so can be used for multiple treatments as required. It is suitable for both hard corns and soft corns.
