Callus is a thickened section of skin that develops due to friction, pressure, or irritation. They are usually yellowish or pale in color and feel lumpy to the touch. Calluses are not usually harmful, but sometimes they may lead to irritation, infections, or ulcerations of the skin, especially among people with diabetes or poor circulation in the feet. Calluses are most frequently found on the bottom of the feet on the bony areas that carry your weight, such as your heels, big toes, the balls of your feet, and along the sides of your feet. They can also occur on the hands, elbows, or knees.

Callus remover products are available in the market, such as topical creams and gels containing salicylic acid, and electric callus removers. However, it is important to follow the instructions on the product package and avoid contact with eyes, nose, mouth, groin, or any broken skin to avoid irritation.

Positive and negative reviews of callus remover products are available on e-commerce websites such as Amazon.
