What are my options for removing the scar across my chest? (Photo)

It's difficult to determine the best solution for you without the benefit of a formal evaluation. Generally speaking, scars can be improved with a combination of surgery and/or lasers and microneedling with PRP. Below is a more detailed reference list of the treatments available. I recommend getting a formal evaluation with a scarring expert to determine which is best for your specific case.
Options can include:
1. Vascular lasers (BBL, Yellow laser, V-Beam, Excel V)
2. Fractional lasers (Fraxel, Erbium, CO2, Halo)
3. Microneedling/PRP
4. Silicone-based scar gels with growth factors
5. Excision/revision surgery

Plastic surgery scars require attention after surgery so that they remain cosmetically-appealing and barely noticeable. In our office, we use a protocol for scars that minimizes their activity in the 6-8 weeks after surgery. If you have late plastic surgery scars, you may also require laser and RF therapy to help reduce the longterm effects of the scarring. Keloids, hypertrophic scars, widened scars, red scars, and hyperpigmented scars all require scar modulation with topical creams followed by lasers and RF therapy. Topical skincare should be directed to a specific need, whether for pigmentation or hypertrophy and our office can guide you through the process to obtain the correct Plato’s Scar cream or Melarase cream for hypertrophy and discoloration. In terms of lasers, we would employ the vbeam laser for redness, Venus Viva RF, PRP microneedling, chemical peels, and Morpheus 8, fractional erbium, or fractional co2. All of these have their individual benefits. Most of all, we recommend you visit a solid plastic surgeon who understands surgical scar revision, laser therapy, and RF therapy for scars.

Hi ,
Your best option would be fractional ablative resurfacing.
You will need several sessions 4-6 weeks apart to reduce the appearance of the scar.
The other option would be Microneedling with radiofrequency but it is less effective.
Hope this helps.
