About Laser Technology

 

The Aerolase Neo’s unique, patented 650 Microsecond Technology® delivers the highest fluence of any medical/aesthetic laser in the world. These highly efficacious treatments are performed safely on all skin types, without skin cooling. The microsecond pulse duration avoids thermally over-stressing the skin and nerve endings. This eliminates treatment pain and diminishes the risk of adverse effects commonly seen with previous generations of long-pulsed lasers.

 

Delivering such high energy in a short pulse duration confines the laser’s energy to the targeted chromophore without escaping to the surrounding skin. This provides several benefits including: precision targeting skin maladies, greater disruption to targeted chromophores, no pre-procedural numbing, and increased patient comfort. This offers virtually painless treatments, better patient experiences, no post-procedural inflammation or erythema (redness), increased efficacy and unprecedented safety. Neo has eliminated virtually all the inherent risks associated with traditional lasers.

 

For laser energy to be effective in aesthetic medicine, the energy must be capable of reaching the targeted structures. The 1064nm wavelength is uniquely capable of reaching the epidermal, dermal, and even sub-dermal / vascular targets in the skin. Only the Aerolase Neo is absorbed by all three chromophores (targets) in the skin: hemoglobin, melanin, and water.

650 Microsecond Technology® 

Typical 1064nm lasers operate with longer pulse durations anywhere from 3 to 200 milliseconds. They are also 50 times longer than the “Thermal Relaxation Time” (burn threshold) of the skin. The burn risk and pain inherent with traditional laser treatments comes from overheating water, melanin, and blood in the skin when it is exposed to the laser energy. This is why patients have associated lasers with pain, burning, and downtime. In reality, lasers possess no heat. It is only the absorption of the laser light by a given chromophore that produces its photo thermal effects.

 

The 650 Microsecond Technology® is a new technology where all necessary power settings can be delivered within a 650-microsecond pulse. This can be done in a variety of spot sizes and at a repetition rate up to 2.0 Hz. 650-microseconds is below the “Thermal Relaxation Time” of skin tissue, so the skin has time to cool itself between pulses. Thus, it prevents damage and inflammation to the surrounding skin. The high-energy pulse is delivered in such a short pulse duration the laser has less time to transfer heat through conduction to the skin surrounding the targeted area. This means the target area reaches a higher temperature in less time than traditional lasers and without burning the skin. Thermal over-stressing of the epidermis is therefore avoided, which reduces the risk of burns or unforeseen, adverse pigmentary changes. Thermal over-stressing of the nerve endings in the dermis is also avoided, making treatment uniquely comfortable and providing better experiences.
