Hypopigmentation After VPL Treatment for Thread Veins, is this Permanent? (photo)

Dear Drs,I had VPL treatment(thread veins)on Dec,2011.Saddly,I got superficial 2degree burns.I try 2be optimist but 2.5mo later I still have hypopigmentation.2-3areas are almost back 2normal,but I really worry that those remaining are becoming scars.I try to massage topically 2improve blood supply.These areas become pinkish with warm water & with massage,& pale with pressure.CouldUplease,if possible,tell me if this hypopg looks permanent or if my melanocytes will work?How long could it take?Thx!
