Treatment is delivered in a series of sessions (usually from 4-6 over several months). The actual treatment delivers laser light or intense pulsed light (IPL) or heat energy directly to the hair follicle causing damage that slows or prevents future growth. Though the technologies employed differ (IPL or diode laser), the basic concept is that the light targets dark matter (the actual hair follicle). The energy of the light is focused and absorbed by the follicle causing specific damage to the area while not heating up the surrounding tissue.
It is important to note that the current technologies work best on light skinned patients with dark, coarse hair. However some hair removal machines have a broader range of treatment options and effectiveness.
Laser hair removal has been approved by the FDA since 1997 for the “permanent reduction of hair growth”. What does this mean exactly?
