The callus shaver consists of a handle, which is usually arched, and a blade made of ceramic or metal.
[1] For this reason the shaver is illegal to be used by beauty salons in some places in the United States.
[2][3][4] A cellulitis infection is possible if the skin is cut, especially if the shaver is shared with others and not properly sterilized.
[5] Treatment with a callus shaver should involve the user in a longer-term care plan.
However, there should be a period of a few days between the individual treatments, otherwise skin irritations and/or an even thicker callus may occur.
