Any benefit or harm to using Polysporin on my incisions? (Photos)

You should discuss this with your plastic surgeons. I prefer tape or silicone to incisions beginning 2 weeks after surgery.  For the first 2 weeks antibiotic ointment is often used, followed by tape or silicone products to improve your scar.

It is best that you clear using this medication on your incisions with your surgeon. At times medicated creams or lotions with fragrance can cause irritation to incisions. It will not impact your seroma healing if used.

Thank you for sharing your question and photographs.  I find that antibiotic containing ointments can cause irritation and redness with prolonged use and I recommend patients use Aquaphor ointment instead.  Hope this helps.
