Function of Intense Pulsed Light System

Intense Pulsed Light (IPL) is a treatment that uses light pulses to penetrate deep into the skin. The photothermal energy gently heats and stimulates the dermis, promoting collagen production and constricting blood vessels, reducing skin redness.


Working theory of IPL Laser Machine

IPL (intense pulsed light) treatment is similar to laser treatment. 

Instead of only one wavelength of light reaching the skin as in laser treatment, IPL penetrates the first layer of skin, called the epidermis, to treat the second layer of dermis. This causes less damage to the skin’s outer layer. The damaged area beneath the first layer of skin is then removed by the body’s natural skin repair mechanisms, resulting in smoother and more youthful skin. 

Light energy is converted to heat within the skin by pigment layers, which destroys unwanted pigmentation and eliminates the appearance of freckles and other unwanted spots.

IPL Working Principle:

Intense pulsed light (IPL) is an intensive, broadband, coherent light source with a wavelength spectrum of 420~1200nm. With these unique properties, the IPL has a wide application in non-ablative therapies based on the theory of human skin tissue’s selective absorption and photothermolysis of the light source.


BBL (Broad Band Light) is skin rejuvenation in mode; it uses the pulse of light energy and gently heats upper layers of skin. The heat absorbed by targeted areas will stimulate your skin cells to regenerate new collagen.
