4 weeks PO. While cleaning my incision my scab came off. Is this normal? Is there a risk of infection? (photo)

Dear LiveBeHappy,
This type of wound is not uncommon after breast lift. It is usually caused by spitting sutures. I would suggest you to consult your plastic surgeon, follow your surgeon's instructions and keep your wound clean and covered. It can take few weeks or months for wound to fully heal.

Thank you for your question and the photo you provided. This type of wound is very common for this stage of recovery, no need to panic at the moment. It would be worth a trip to the board certified plastic surgeon who performed your procedure so they can see and examine you. They will be able to discern your risk for infection. They will also be able to tell you how to properly clean and manage the wound so you don't scar poorly to that area. Good luck!
