In my opinion Vit E should've completely removed for at least 2 weeks prior to surgery as should alcohol, herbals, fat burners , and all NSAIDS.
These all contribute to bleeding or react unpredictably with anesthetics.
Discuss with your board certified plastic surgeon
Vitamin E, arnica, and antiscarring treatments and surgery.
Very high dose Vitamin E has been reported to increase bleeding, but the amount found in multivitamins and food will not have any effect. Arnica has been anecdotally reported to decrease bruising, but careful studies have been decidedly mixed as to whether there is any benefit. It is certainly safe, but in the absence of convincing data, many surgeons including myself do not recommend it. Regarding anti scarring treatments, again there are many treatments out there with anecdotal positive results, but the only therapy to have careful studies repeated demonstrating effectiveness are silicone gel sheets or creams. I routinely recommend them to patients, and suggest you talk to your surgeon about them. They do not eliminate scarring but in many patients, silicone gel reduces scarring when used postoperatively.
Every surgeon has different recommendations for post-op care. Best to follow his instructions. Good luck.
