The future king - who has been pictured sporting a small white plaster on the bridge of his nose following the operation - underwent the surgery last week at royal residence Clarence House.
The growth was removed without the need for a local anaesthetic.
A spokesman for Charles said: "It was a routine and minor matter. It was done here."
The procedure was performed after the prince had met the Dalai Lama at Clarence House.
The British Royal Family have a history of receiving treatment for growths on their faces.
Charles' father Prince Philip underwent a minor procedure in 1996 to erase a small benign growth on his nose.
In January 2003 Queen Elizabeth had minor - non-cancerous - growths removed from her face by surgeons.
