IPL vs Diode Laser
With so many methods available for hair removal in the market, we can survey two fundamental types: intense pulsed light (IPL) and laser-based methods.
Intense pulsed light (IPL) uses broad-spectrum light with varying wavelengths that penetrate the skin at different depths. Compared to a laser, which uses a single-spectrum light, IPL gives off light energy that is weaker, more dispersed, and less targeted.
An IPL device emits pulses of light, which are absorbed by the pigment in hair follicles below the skin’s surface. The light turns to the heat that is absorbed by the skin, and essentially destroys the follicle—causing hair to fall off and regrowth to slow down significantly, at least for some period of time.
Broad-spectrum light naturally spreads out, allowing IPL hair removal devices to cover relatively larger areas of skin than laser hair removal devices. So, IPL treatments are generally faster but more IPL sessions are required to get the same results as laser hair removal procedures
Standard IPL hair removal devices work best on lighter complexions with dark hairs. However, some hairs may be light on the surface but have dark follicles underneath. For these types of hair-skin combinations, IPL also produces results, especially the more advanced IPL devices.
Although different methods offer varying benefits and advantages, this kind of hair removal is the proven method for the safest, fastest, and most effective hair removal for patients of any skin type and hair color combination.
