Lasers Confusion

Theodore Katz, MD answers: KTP Laser to remove brown spots?

I have one large brown spot on my face about 1 cm in diameter. I went to see a dermatologist who told me that his office can use KTP Laser to remove this brown spot and smaller ones around the face.

But then I read online that KTP Laser is use to remove red vessels on the face? I'm confused.

If you are confused, then ask questions! Of course then you must decide which questions to ask and this is where a lot of patients get confused. How do you know what to ask? Lasers are different becauue they generate laser light in different wavelengths and therefore have different effects on the target tissues. Some lasers are better for wrinles, some for vascular lesions (hemangiomas, telangiectasias or small blood vessels), some for brown spots, some for pigmentation, some for hair, some for fat, some to tighten skin, and on and on. If the only laser that your physician has is the KTP, then that is the only one he/she will use whether it is the best or not. Seek a second opinion by an experienced laser physician who can determine what your particular problem is, what the cause is, and which laser would best treat that. Most experienced laser physicians do have more than one laser in order to address different problems. Do not be afraid to ask the physician what their experience and background training is, how long they have performed these procedures, what results they have achieved, what are the risks, how often to complications arise, how are complications treated, etc. It is complicated, but it is YOUR body. Protect it and arm yourself with information.
