    What are the treatment options for vitiligo and how do you choose?

    Vitiligo treatment is divided into phototherapy, topical medications, oral medications, and procedures. By organizing each treatment according to how it works in the body, you can make a more informed choice. Recently, a new class of drugs called JAK inhibitors is gaining attention.

    Can the Parkinson's drug levodopa help prevent vitiligo?

    How much change counts as a meaningful improvement in vitiligo?

    There are scores that measure how extensive vitiligo is: a clinician-assessed extent score and a patient self-assessment score. This international study identified the threshold of change in these scores at which patients feel they have 'truly improved.'

    Does excimer laser for vitiligo need to cause redness to be effective?

    We compared excimer laser applied with enough energy to cause the skin to turn red versus excimer laser applied gently enough not to cause redness. In both cases, Protopic ointment was also applied. This trial aimed to find a balance between safety and effectiveness.

    Can vitiligo develop on scars or wound sites?

    This is a case of vitiligo developing on a keloid scar. It is an example of the Koebner phenomenon, where the disease appears on irritated skin, and shows why it is important to reduce unnecessary skin irritation in vitiligo.
