2 months ago I had pulsed dye laser treatment to treat thread veins by a qualified dermatologist but this has left me with marks from where he used the machine and if I get hot, my skin goes bright red and is very embarrassing.
He gave me Tretinion which to date has had no effect. I don't know if I have hypo pigmentation or hyper pigmentation. Can you help? I do now know what to do and if it is permanent damage. Thank you.
