For an adult man, this scar usually lies about 2.5cm (one inch) from the glans or coronal ridge. The scar is located at the boundary of the inner foreskin remnant, which is the portion of the foreskin that was not removed during circumcision. This foreskin remnant is mucosa that lies between the glans and the circumcision scar. The foreskin remnant can often have a different color and texture than skin. It can be pinkish or light-colored, and it can be covered with keratin to protect it from a dry environment.
The type of circumcision scar is dependent on the technique being used. Some circumcised men have a prominent or uneven scar, whereas in others it is less noticeable. There are numerous creams available which, when applied regularly to a recent circumcision, can significantly diminish the visible scar line, sometimes to the point that it becomes effectively unobservable except to a medical professional. The appearance of the scar can be reduced through the process of foreskin restoration. A completed restoration normally results in the circumcision scar being completely hidden from view on the inner surface of the regrown prepuce.
Occasionally, the scar can swell or become irritated during intercourse. Some men with significant amounts of scarring have used cream or silicone scar pads to cause the scar to fade
