What do calluses look like?

Calluses appear as thickened, hardened areas of skin that develop in response to repeated friction or pressure. They often have a yellowish or grayish color and a rough texture, sometimes appearing raised compared to the surrounding skin. Common locations for calluses include the hands, feet, and fingers, particularly on weight-bearing areas like the soles or on the palms. They generally do not cause pain unless they become overly thick or cracked.
