When your procedure is finished, bandages or dressings may be applied to keep the surgical site clean. The final results of your scar revision surgery will be long-lasting, however it may take several months for your final results to become apparent and in some cases it may take a year for the new scar to fully heal and fade. Although good results are expected from your procedure, there is no guarantee. In some situations, it may not be possible to achieve optimal results with a single surgical procedure and another surgery may be necessary.
