Regarding hair removal, the drs.who have laser(gentilase, diode)say it's the best, same for ones having ipl.if my skin match all which the best?

Laser: Each doctor will probably say the laser they have works best. Obviously all of these lasers do work. If you have light skin and dark hair, i think alexandrite lasers such as gentlelase, with a wavelength of 755 nm work very well. Ipls tend to be versatile machines that generate a high intensity beam of light, but are not lasers. I prefer laser machines that do a specific job over ipl machines.

Laser works better: Depending on skin type, laser works better for hair removal than ipl. For paler skin types, alexandrite laser works well. For darker skin types, ndyag laser is a better choice.
