What to do if foreskin grows back after circumcision?

I don't see how: I don't see how it will. When you cut something off, how can it grow back?

Steroid cream: The foreskin will not grow back, but occasionally, adhesions can form between the shaft skin and the head of the penis following a circumcision, this usually only happens with young children but can happen with adults. The treatment is steroid cream, either Betamethasone or triamcinilone, applied to the adhesions twice a day for 6 weeks.

Gently Retract: The foreskin really does not grow back, but what is left can stretch towards it's former place.Gentle retraction prevents any problems.

Usually do nothing: Foreskin does not grow back. Sometimes surgeon leaves a little extra skin, which is better than removing too much. Many little boys develop or have a prominent fat pad in front of pubis which pushes penile shaft skin forward. This can adhere to glans + gives impression that foreskin has grown back. Leave it alone + it will separate with passage of time. Epithelialized skin bridges need division.
