I know you posted this last year- im sorry you havent gotten any responses.
If it's progressed that much and quickly- I'm not sure any treatment option would benefit you. It's covering a large portion of the body. Cost is a big thing as well. To my knowledge, most insurances won't cover it. So it would be out of pocket. I've tried UV light and a topical ointment cream (can't remember the name) and didn't get much from either and it was extremely expensive and at the end of the day just wasn't worth the hassle. And there isn't anything out there that will take it away permanently. You'd have to continue treatment for the rest of your life. I'm 27 y/o now and had my treatments done back in middle school. I don't know what all is out there now- I started and stopped treatment in middle school. Cost and stressed me out more. I hate my skin, but it is what is is. I wish you the best of luck. I'm sorry you have Vitligo.
