Dear Ms. Edie940,Thank you for your information and questions.Proably won't make a significant difference. However I would recommend not to:1) bacteria may be in the spray tan2) antiseptic wash may remove the chemical tan and result in a uneven body tan3) not sure what tanning chemicals are used and potentially alter wound healing/scar formatuoon.I recommend that you check with your chosen Plastic Surgeon who I trust is experienced and Certified by the American Board of Plastic Surgery. In addition ideally they he/she is a member of the American Society for Aesthetic Plastic Surgery (denoting by membership as having met additional criteria and a focus on Cosmetic Plastic Surgery).I wish you my best and success,R. A. Hardesty, MD, FACSDiplomate and Certified by the Am. Bd. of Plastic Surgerywwwimagineplasticsurgery.com4646 Brockton AveRiverside, Ca 92506(951) 686-7600
