Comparison of laser methods (money, pain, effectiveness)

I would like a comparison of laser methods (laser, ipl) regarding money, pain and effectiveness.

I live in Cyprus and a company ( advertises that Photolysis (multiple wavelength lamp) is much better than simple laser regarding pain and effectiveness. But it is also much more expensive than simple laser.

Is it true that photolysis (IPL) is better than laser?

PS: I read from that photolysis is a marketing term for a flash lamp procedure using multiple pulses. So what I am really asking if flash lamp using multiple pulses is better than laser (single pulse)
