The Lovely II is the world's first non-ablative and ablative system that combines different lasers, UVB and pulsed-light source technologies all on a single platform. The system's unique capability allows versatility and flexibility with respect to therapeutic choices for clinician and patient alike, without the need to rely on individual and expensive laser-based or light-based systems. The Lovely II platform signals a breakthrough in the future of procedural laser and light-based dermatology. No longer will an individual system need to be dedicated to each aesthetic application (currently ~10-15 such applications are applied routinely); no longer will doctors rely on oversized systems that take up too much floor space; no longer will systems involve bulky articulated arms, delicate fiber optics, or high service costs. Instead, one powerful system will be able to address a large variety of clinical indications for single or combined therapeutic regimens.
CUTTING EDGE TECHNOLOGY
The LEO technology refines pulse width, pulse shape and fluence parameters using the most efficacious optical energy for a wide range of indications through two precision proprietary technologies:
Advance Fluorescence Technology (AFT™) is a special filtering system inside each AFT handpiece that converts the lamp's unused short wavelengths (below the cut-off filter) into a clinically optimal spectrum by selectively amplifying emissions in the blue, red and green portion of the spectrum. This unique filtering system enhances penetration without using excessive energy levels, thus protecting the epidermis, resulting in safer and more effective clinical outcomes for hair removal, acne clearance, skin rejuvenation, and vascular and pigmented lesions.
Equally Distributed Fluence (EDF™) represents an innovation in electrical engineering that enables emission of square-shaped pulses in order to achieve true long-pulse performance with moderate peak power throughout the entire pulse. One of the major limitations of today's IPL technology is the unfortunate structure of time sequences of very short duration (2-5msec), yet very high peak-power pulses. While this approach can supply sufficient average power to properly affect many cutaneous targets, it also increases the likelihood of adverse side effects, such as blistering, pigment alteration, textural changes and even hypertrophic scarring.
Lovely's EDF, in contrast, delivers similar heat (because the average power is similar) but is safer for the skin because the peak power is lower. This innovative pulse output enables safe treatment of dark skin and ensures even greater safety with lighter skin tones. In fact, Lovely's EDF is so effective it obviates the need for the complex integrated cooling systems that are generally required with IPL systems.
SPECTRUM OF LIGHT
The Lovely II platform incorporates five different light-based handpieces for operating in the visible/near-infrared spectrum, and one for the ultraviolet (UVB) spectrum. The optical window of each handpiece has been designed in accordance with specific clinical indications and their unique endogenous, biological chromophores:
- Psoriasis and vitiligo (300-380nm; proteins and lipids)
- Acne clearance (420-950nm; porphyrins and photosensitizers)
- Vascular and pigmented lesions (540nm-950nm; oxy/deoxy-hemoglobin, melanin)
- Skin rejuvenation (570-950nm; melanin, hemoglobin)
- Hair removal (650-950nm; melanin)
LASER CONVERGENCE
The Lovely II platform features four discrete laser modalities (non-ablative and ablative): a long pulse, neodymium- doped yttrium- aluminum- garnet (Nd:YAG) at 1064nm for treatment of enlarged and deep leg veins and fine wrinkles; quality switched (QSW) Nd:YAG at 1064/532nm with KTP for treatment of dark and light ink tattoos and dermal pigmented lesions; 1320nm Nd:YAG for treatment of wrinkles and acne scars; and 2940nm erbium YAG (Er:YAG) for skin resurfacing. Each handpiece is pistol-shaped and connected to the system console with an umbilical cord containing wiring and cooling water tubes. The pulse widths and repetition rates (pulse per second) are preprogrammed according to the handpiece's intended application.
BRINGING IT ALL TOGETHER
The Lovely pulsed-light and laser system is compact (65 x 45 x 40cm) and transportable (40kg without cart). The computer-controlled system requires just a short learning curve and minimal maintenance. The Lovely II system is comprised of a main console, a universal connector that receives each laser or light-based LEO handpiece, and a footswitch. In addition, it includes a simple array of controls and indicators, including a main-power switch. The Lovely II system is comprised of controls and indicators, including a main switch, a key switch, an emergency shut-off knob, a pulse laser and light emission indicator, and an LCD display screen. The system's console resides on an ergonomically designed, movable cart.
Lovely II operates with up to nine interchangeable handpieces representing three different technologies:
- LEO - 4
- UVB - 1
- Laser - 4
In all cases, the photon source resides inside each handpiece and has been pre-configured to a certain energy range according to its intended use. The operator can adjust the energy fluence within the predetermined range, and in most cases choose the pulse duration or repetition rate. Each LEO handpiece enables the operator to choose between three pulse widths: narrow pulse width for light skin type (Fitzpatrick I-II); medium pulse width for darker skin type (Fitzpatrick III), or wide pulse width to be used on dark skin types (Fitzpatrick IV-VI). In the case of laser handpieces, the operator can choose between three different repletion rates.
The universal connector enables simple swapping of handpieces whenever needed. The connector's socket is located on the right side of the front panel below the LCD display. Each handpiece is connected to the system console with a flexible umbilical cord containing wiring and cooling-water tubes. The system can only be operated when a given handpiece is connected to the main console, which can automatically sense and recognize which handpiece has been connected, as well as set up the necessary parameters, pulse widths and energy fluences for each handpiece's application.
