Thanks for posting your query.
Healing is a natural process and a good diet and a stress
free life are the best healers.
Still to increase the growth of the foreskin you can apply a 1% hydrocortisone
ointment available over the counter. You can use the ointment twice daily after cleaning the area.
Avoid touching the area with bare fingers repeatedly and wear cotton undergarments to reduce any inflammation or friction rub in the affected area.
I hope this answers your query.
In case you have additional questions or doubts, you can forward them to me, and I shall be glad to help you out.
Please accept my answer in case you do not have further queries.
Wishing you good health.
Dr. Praveen Tayal.
