Too aggressive halo/bbl treatment on chest. Will this scar? What can I do? (photo)

I agree with my colleagues below.   It appears that your provider over lapped the middle portion.  Looking at your settings they are on the high side for chest to start with.     Over time the redness will fade.   Continue to protect it from the sun.   I also, like the Sente Dermal Repair for redness. Best of luck!

Sorry to hear about your prolonged recovery! I believe this will ultimately heal completely. The area in question has very thin skin and can take longer to heal. As strange as it sounds the treatment to improve the redness is actually more laser (in the form of BBL or Pulsed Dye). These lasers can help improve the redness more quickly. Although this has been a longer recovery than you'd hoped for I suspect the chest will ultimately heal well and will age better for having had a more aggressive treatment. Best of luck, Dr. M

I have seen this before.  It is most likely from BBL.  The area directly over the breastbone is at increased risk for thermal injury (just like the forehead).  I am very hopeful it will heal...but may take about six months.  If there is any residual discoloration after that time, then one can use some other treatments to reduce the discoloration. A very good chance it will go away entirely.  

if there is persistent redness on the chest, I would likely start treatment with pulsed dye laser. This is a non-invasive treatment which would likely help. Usually pulsed dye laser is repeated more than once. It is very important to protect the area from sun exposure with a zinc oxide sunscreen. If you’ve lost trust in your doctor, you need to find another doctor.Regards,Dr. Ort

thank you for your question. I’m sorry you have this result. It looks as if he simply overlapped that area of your chest between the two halves and therefore increased the treatment in that location. From your photos it looks like you have some post inflammatory changes which should resolve in time (on the face I normally estimate 4-6 weeks. On the chest roughly double) My suggestions start with daily spf to that area; to prevent hyperpigmentation sunscreen is your best defense. A second adjuvant I like is Alastin skin nectar to help more rapidly repair damaged skin. A few Light bbl treatments or pulse dye can also help to reduce the redness.
