No skin product necessary prior to surgery.
I know of no valid scientific literature to support a specific cream or lotion prior to surgery. However, it is important to moisturize and take good care of your at all times. So stick with a consistent skin care program. Don't put any oils, creams, or lotions on your skin on the day of surgery. It could make it difficult to prep your skin with the cleansing soaps at the time of surgery. Also, don't tan.
