How long does it take a keloid scar to lighten, with a pulse dye laser?

Thank you for your question. Treatment time varies depending on the scar. Your provider should have a time frame for you. If not then consider consulting with a Board Certified Plastic Surgeon for a treatment plan.

You should see a cosmetic dermatologist who is an expert in scar treatments.  Combination laser treatments and injections are the appropriate treatment but will require many treatments and is individualized based on the initial apperance of your scars and your ultimate expectation.  Best, Dr. Emer.
