Question: how long do you use vaseline after circumcision for newborn?
Answer: Even after the dressing is no longer needed, you should put a dab of petroleum jelly on the penis or on the front of the diaper for 3 to 5 days. This can help avoid discomfort from rubbing and sticking to the diaper. It usually takes between 7 to 10 days for a circumcised penis to heal from the procedure.
