A Thank you for your question. Please keep in mind that it is best to be seen in person for a consultation with a board certified plastic surgeon to receive the most thorough treatment plan.
A scar that is indented can be filled with filler. Bellafill is nice because it does last longer than a hyaluronic acid filler such as Juvederm and it also helps stimulate collagen production. Incorporating PRP with the treatment will enhance the stimulation of collagen even further.
A surgical revision may be necessary if there is separation of tissue, however. Again, find the right provider for you in your area so that any issues in the future can be addressed locally.
