If the foreskin has any cuts or tears, it is recommended that the area should be kept clean and dry to avoid developing an infection. You may use a gentle antiseptic, such as hydrogen peroxide, to clean the wound and encourage tissue regeneration. Do not use soap on the affected area or scrub it roughly, since this will only worsen the situation. Any cuts that are deep or fail to heal within a few days should be treated by a health care provider.
