YLITE



Revolutionary skin rejuvenation Intense Pulsed Yellow Light (IPYL) is laser generated ordinary light of the perfect wavelength for skin rejuvenation.

Intense Pulsed Light (IPL) technology provides reasonable results for hair reduction but offers poor results for skin rejuvenation including vascular lesions. The reason for poor results is limited power required to focus in the haemoglobin and porphyrin absorption region (about 578nm in the yellow). The limited power in the required region means that users often increase the fluence to obtain the results often causing collateral damage to the surround skin, tissue and vessels. This is particularly true for darker skin types where the green content in the IPL output is more strongly absorbed by melanin, the skin pigment.

The YLite produces high power with short pulses up to 22,000 per second to work on the vessels, tissue and pigmented lesions specifically without effecting surrounding areas not required for treatment. The unique designed handpiece with finger trigger has a 1mm spot size tip to allow for the yellow light to focus in the dermis. 1mm is the desired size to treat only the targeted areas.

The lightweight ergonomically designed handpiece enables practitioners to view all treatment parameters on the handpiece's in-built display screen, which provides skin photo rejuvenation in contact mode and treatment of all benign skin lesions, brown age spots and facial unwanted red surface veins precisely and with minimal discomfort to the client due to chromophore specific wavelengths and efficient powers that reduce the exposure time and therefore provides unprecedented protection against unwanted skin damage to surrounding tissue.

Operating Principal

TThe YLite has an imbedded Class 4 Copper Bromide Laser. This system is used to produce monochromatic light of sufficient intensity and collimation for the purpose. The light is delivered to the applicator via a fixed optical fibre which is fully protected from damage. No access to the laser or the optical fibre is possible by the operator and all emissions from the laser enclosure are maintained well below class1 levels.



Comparison with devices making similar claims, a wide range of IPL devices exist on the market as Cosmetic devices and are used in Beauty therapy, a few of these devices are listed.

Emission Wavelength

The typical IPL has broad band output covering 500 to 1000nm as a result of using a flash lamp source compared to the YLite narrow band output at 578nm. The narrow band output has the following safety advantages: 1. Eye safety - It is impossible to provide adequate eye protection yet provide reasonable vision for broad band sources. The YLite narrow band output is very easily completely filtered out in safety glassware leaving good visibility. 2. Collateral damage - Broad band sources used in IPLs contain mostly unwanted light this light may result in undesirable collateral damage which has been reported as hypopigmentation.

Output energy

As a result of large spot sizes and broad band light IPLs generally produce very high energy output, typically more than 100J, and yet are very ineffective. The YLite has a maximum output of only 2J and so is intrinsically a safer device.

Treatment Area

IPLs typically have a relatively large spot size, many in the industry equate this to faster treatment but small spots are preferred so that the light can be contained to only the required area. For the following reasons the YLite is not a medical device but is classified at least similarly to IPL devices:

  • The device is used purely to enhance the cosmetic appearance.
  • It is much lower powered than all IPL devices which are classified as cosmetic devices.
  • It is much safer to use compared to IPL devices.
  • A Class 4 laser is used to generate pure Yellow Light.
