LUTRONIC LASER AND IMPROVED HAIR REMOVAL
In this article, the benefits and efficacy of the ADVANTAGE Laser System from Lutronic, Inc. are discussed
H ARNESSING THE
full capabilities of familiar 805 nm diode laser technology, the ADVANTAGE Laser System from Lutronic,
Inc. (Fremont, Calif., USA) offers excellent efficacy for hair removal in a large range of skin types, including darker-skinned patients. Users will also enjoy the device’s ability to improve the appearance of vascular and pigmented lesions. This versatile device received FDA clearance for laser hair removal in early 2012, and is also a recent recipient of CE marking.
Key benefits ‘The results with ADVANTAGE are very satisfying for myself and my staff, as well as our patients, and the device is relatively simple to operate,’ said Wooseok Koh, MD, director of JMO Dermatology in Seoul, South Korea, and lead investigator for clinical trials with the device. ‘Treatment is very easy to customise, so users may adjust parameters to maximise outcomes and more effectively deliver therapeutic energy while managing patient comfort.’ According to Dr. Koh, one key benefit to the ADVANTAGE Laser System is its reliance on solid state

engineering and a proven laser technology. ‘The 805 nm diode laser is a modality that practitioners around the world are very familiar and comfortable with, both in terms of scientific understanding and clinical use. It can be used on a wide range of skin types from light to dark skin.’ Energy delivery itself is optimised through the use of powerful semiconductor diodes in stacked arrays.
Another benefit is the independent
adjustment of fluence and pulse duration. ‘Difference of hair thickness between patients is easily overcome by modifying the pulse width,’ Dr Koh said. ‘To my knowledge, other systems on the market feature fixed pulse duration, or limited & fixed combinations of pulse duration and fluence.’
The mechanism of action with
ADVANTAGE for laser hair removal occurs as follows. As the tip compresses skin in the treatment area, blood flow is temporarily displaced and contact cooling protects the epidermis. Melanin absorbs delivered laser light energy, which is converted into thermal energy and causes thermal damage via the principle of selective photothermolysis, which destroys hair follicles, stem cells, and dermal papillae. The difference is in the efficient delivery of energy, according to Dr Koh. ‘With devices operating at a lower
peak power, we see heat dissipation at the follicle and reduced efficacy. Treatment requires longer pulse durations and more sessions are required to achieve the final result the patient is hoping for. Lutronic ADVANTAGE Laser System offers
