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 in to 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.
