Your doctor usually will cover the shave biopsy wound with a water proof dressing. You can keep the dressing on for 24 hours. After that, you can consider bathing, shower over the biopsy region.
Ensure the wound site is clean and dry (pat dry after shower), and you are encouraged to apply antibiotic cream (which your doctor will prescribe) and a vaseline ointment to the wound region to promote healing.
You may cover the wound with a light water proof dressing if the wound area tends to rub or scratch on clothing or other surfaces.
If you notice your shave biopsy wound is slightly oozy after the procedure, apply a constant and firm pressure onto the bleeding site for 15-30 minutes. You can try 1 more cycle if it remains oozy. If persistent bleeding, you are advised to reach out to your doctor.
