How long after surgery can I have laser on incision to improve appearance?

Thank you for your question. Excision is one way to address prominent scarring, but you are exchanging one scar for another. Your doctor should provide you with protocol to treat your scar in the early days after your excision, including the application of a silicone gel and keeping the scar out of direct sunlight. Once you have healed from the procedure, you can start looking at laser treatments or other methods to minimize the scar. Keep in mind that scars will continue to improve for many months on their own as long as they are not exposed to direct sunlight. 

Great question, thank you!  There are multiple ways to help improve the appearance of a scar.  Excising them is a great way, yet you trade a scar for another scar.  Often times if the scar is placed well you can hide it in an existing line or crease to help minimize the appearance of the scar.  Yet on the back this becomes a bit more challenging as there are very little existing creases or lines!  The scar on its own will improve if given enough time.  Initially the scar will appear pink and have a bumpy texture to it yet as the scar matures the color will face and the scar will smooth out.  There are also different creams, light or laser treatments that can be done to minimize the scar, yet I would recommend allowing some time for your body to heal the scar before beginning any of these treatments (at least 4-6 weeks).  I would also keep close follow up with your surgeon to discuss your concerns with him/her and to determine which treatment will best benefit you and your goals.  Thanks again for your question.  Best wishes, Dr. Lindsay J Sturm. 

Thank you for your question.
Scars can be treated with multiple approaches depending of the needs. Laser will help to improve the pigmentation changes, cortisone injections will work if there's thickening of the scar tissue or topical which will aid in the healing process. After your surgery goes through, everything will start to heal but it will take time to close. Once the incision heals completely get the area assessed by your doctor so they can approve for you to begin scar treatments. Ideally when the incision fully closes you can start applying a silicone gel to aid in the healing process swell as using a micro roller with growth factors. These help to soften the tissue and accelerate the rate of healing by promoting collagen in the area. Healing can take multiple months and if there's any dark pigmentation or redness, then it can be treated with VBeam, Genesis or Laser Toning. Discuss with your specialist which laser would benefit your skin tone and the scar post surgery, review risks and side effects and the benefits of these. 
I hope this helps.
