a peak power of 2800 watts, which delivers more energy at shorter (but adjustable) pulse durations. We see reduced lateral heating, as therapeutic energy is concentrated at the follicle, which should theoretically improve efficacy and reduce treatment time. Further study is required to further enhance our understanding of this relationship.’
Specifications The ADVANTAGE Laser System features two handpieces: the D1-800 with a 10 mm x 10 mm spot size, and the D3-800 with its 10 mm x 30 mm spot for larger areas. Either handpiece is ideal for hair reduction or removal. For vascular or pigmented lesions, users would choose the smaller spot of the D1 handpiece. Contact cooling (3°C) is incorporated into each handpiece. ‘The combination of optimised
energy delivery, large spot size, and contact cooling work together toward two important ends: reduction of treatment time and improvement of patient comfort, which themselves are linked together,’ explained Dr Koh. ‘Because of the nature of laser hair removal treatment as we know it today, doctors expect some discomfort. ADVANTAGE allows us to balance patient comfort with energy delivery to provide therapeutic doses safely, within the boundaries of individual patient tolerance.’ For example, as lead investigator
for clinical trials with ADVANTAGE, Dr. Koh shared his favourite settings. ‘For hair removal in Korea, my staff and I rely on the D3 handpiece delivering between 24 and 27 J/cm2 with 40 ms pulse duration or 28–30 J/cm2
at a pulse duration of 45 ms, combinations which we

have found to be very effective for hair removal, which is the primary modality associated with ADVANTAGE Laser System,’ he said. ‘In my experience with Asian
patients we require fewer treatment sessions than usual to remove unwanted hair, in comparison to systems I have experience with. Data from treatment of the leg and axilla has shown average clearance of 60% of unwanted hair after only three treatments in ongoing studies; we look forward to reporting the full results soon.’
Efficacy and versatility Given the worldwide variety of skin and hair types, Dr Koh is optimistic that ADVANTAGE Laser System is exceptional because its efficacy is enhanced by its versatility. ‘Once a doctor becomes familiar with the versatility of the ADVANTAGE Laser System, they may successfully explore their own favourite protocols because of the adjustability of the device. This is a key benefit around the world, because all populations and skin types experience the desire to remove or reduce unwanted hair. Additionally, the platform is designed to be expandable, so we expect to see the device’s capabilities further augmented in the future.’ Furthermore, there are minimal consumables and no disposables associated with the ADVANTAGE Laser System. ‘In every clinical setting, regardless of location, it is helpful to both patient and doctor.’
Conclusions As Lutronic strengthens its position in the global market for aesthetic laser devices, Dr Koh believes its reputation will rest on a few specific points. ‘Lutronic devices share some

important characteristics,’ he began. ‘They are very reliable and of high quality; the company is quick to resolve what few problems may occur. Next, the devices are very easy to use, featuring top-class intuitive touchscreen displays that simple to understand and operate. Most important is that Lutronic devices provide safe and effective treatment. They are high quality devices worthy and capable of workhorse status in the aesthetic practice.’ ‘I’m a strong proponent of
evidence-based medicine,’ added Dr Koh, ‘and I think Lutronic has worked not only to provide safe and effective devices, it has also laboured to advance the science of treating Asian skin, which is traditionally challenging to treat. The capabilities of ADVANTAGE should be of great benefit to European users as a result of this diligence with regard to science.’
