The Syneron ELOS Technology laser combines a diode laser at 900 nanometers and bipolar conducted radiofrequency (“RF”). The unique properties of combining and layering laser and RF is described as Matrix Heating, which results in the desired and profound heating of the dermis necessary for wrinkle reduction. Matrix Heating effectively creates “pockets” of heat which results in fibrosis, or scarring of dermal tissue. This activates fibroblasts signaling new collagen to form and existing collagen to tighten as a response to perceived injury. This differs from the traditional methods of wrinkle reduction and their limitations: ablative laser skin resurfacing or non-ablative weak dermal heating lasers and light sources. Effective heating of the dermis is achieved through this Electro-Optical Synergy (ELOS) while the remodeling is achieved in 3-5 treatments with the Syneron ELOS Technology laser.

Laser – 900 nanometers diode
The wavelength of the laser bypasses the epidermal melanin barrier. This is due to the relative weak absorption of 900 nm by superficial melanin, allowing even darker skin to be treated. The superficial epidermis is protected from thermal over-load by the contact cooling on the applicator tip.

Radiofrequency (RF)
The RF energy is conducted through bi-polar electrodes, and safely distributes heat to the dermal layers. The peak current density for RF is about 1.5 to 2 mm in depth. This is determined by the geometry of the bipolar electrode design, where the approximate depth of penetration is half the distance between the electrodes. RF has been used in medicine and surgery for a century and poses no long-term risk. The contact cooling at the applicator tip lowers the temperature of the epidermis, thereby forcing the RF down into the dermis.
