Is laser useful in the cure of white patches

Q: Thanks for the information on the treatment of white patches. Further, I am eager to know how far is laser useful in the cure of white patches? Is it advisable? Please let me know.

A:Depending on the cause: hypo-/de-pigmentation due to fungal infection or post-trauma, there is no role. In patients with vitiligo(with active disease)lasers may lead to further progression of patches.
