THE USAGE AND ADVANTAGES
OF LUTRONIC SPECTRA Q-SWITCHED LASER
What do I need to know about Lutronic?
Lutronic is one of the world’s leading developers and manufacturers of medical laser systems serving the clinical dermatological and esthetic communities. With the honor of award-winning technology design that includes its Spectra line of products and its unparalleled MOSAIC Systems, the company is focused on conveying innovative, highly effective, and painless laser solutions.
What are spectra?
Spectra is a gentle laser that delivers specialized nanosecond laser energy to decrease visible skin pigmentation. Spectra improves uneven pigment, as well as decrease the presence of textural irregularities and fine lines. This device targets the most common problems of the skin, including pigment, melasma, skin tone and post-inflammatory hyperpigmentation (PIH) with reliable results, and it is agreed upon by many clinical studies. Moreover, SPECTRA is an Nd: YAG based system, working at 1064 nm with frequency multiplying for 532 nm capability. Furthermore, it also features two optional handpieces: 585 nm and 650 nm stable dye lasers pumped by the 532 nm wavelength which are used mostly for tattoo removal, additionally increasing the platform’s versatility.
What feature does the Lutronic Spectra Q-Switched laser have that others don’t?
Lutronic, one of the world’s leading developers and manufacturers of medical laser systems, reported a couple of years back that it has received FDA clearance to advertise its Spectra VRM III. This dual pulse Q-Switched Nd: Yag laser is the element rich successor to the Spectra VRM II. The laser produces four wavelengths (1064 nm, 532 nm, 585 nm, 650 nm) in Q-switched nanosecond pulse. It is specifically designed to treat a wide array of dermatological and esthetic conditions including, dermal and epidermal pigmented lesions, multicolor tattoos, melasma, and active acne. It additionally enables laser toning, and non-ablative photo-acoustic skin rejuvenation techniques. The laser incorporates a dual pulse mode, which allows it to create short and quasi-long microsecond pulses. There are numerous advantages which result from the unique pulse characteristics not found in other lasers including extreme high peak power and a level top beam profile. ”
What concept does the treatment with Lutronic Spectra Laser rely upon?
Treatment with Lutronic spectra Laser relies on a concept that has been called subcellular selective photothermolysis, based on the first concept of selective photothermolysis first published by R. Rox Anderson, M.D.,”. The high peak power (incident irradiance of about 400 mW/cm2) delivered in the ultrashort pulse width of the Q-switched mode creates an almost instantaneous and pure radiant heat effect specific to the melanin absorbing the laser energy, barring the surrounding tissue components. Since the thermal relaxation time is constrained to a couple of nanoseconds, little or no heat is allowed to escape to surrounding tissues, instead concentrated towards the destruction of the target chromophore into microparticles, which the body eliminates naturally.
What are the uses of Lutronic Spectra Laser?
The Lutronic Spectra Laser is a Q-switched 1064 laser that has a tremendous affinity to pigment. It is designed for (and state of the art for) tattoo removal and treating various pigmented lesions (post-inflammatory hyperpigmentation, seborrheic keratosis, freckles, lentigos, nevi, and melasma). The laser begins by setting a carbon liquid on the skin for around 10-15 minutes. The carbon is absorbed superficially in the skin. This liquid is essentially tricking the laser into intuition its attacking pigment when it is applied to the face. As the laser is initially passed over the skin, the carbon absorbs little heat and pass it to the underlying skin. The several subsequent passes cause vaporization of the carbon as well as an extremely superficial layer of the skin – 15-30 microns. What makes it gratifying is that there is no discomfort during the procedure!
What’s unique about this type of laser?
What makes this treatment procedure unique is that its pulse duration (to what extent the time is which it fires its energy) is in the nanosecond range. By making the pulse this short, it develops the energy level of the pulse in billions of watts. This immense energy hit the tattoo, or any pigmented lesion causes a shock wave in the pigment which leads to the dye breaking up into smaller pieces. Once the particles of the pigment get pulverized to a specific size, they are sufficiently small for the body to “eat them up” and expel them from the body. Using traditional laser techniques, it takes multiple treatments, 10-15, to get complete removal of tattoos or any pigmented lesions. Often the holding up between treatments is up to 2 months, so it can take a year to 2 to have a total removal.
Why Is the Lutronic Spectra Q-Switched Better?
Traditionally, the 585 nm dye lasers used moderately long-pulse widths (many milliseconds) to thermally damage and coagulate the blood vessels. This treatment, however, may cause undesirable thermal damage to the surrounding tissue and consequently often caused bruising. Lutronic has presented the 5mm Gold 585nm handpiece onto the 5 nanosecond Q-Switched Nd: YAG Spectra laser. The extremely short nanosecond pulse, a thousand times shorter than a millisecond, and the low fluence used for treatment, reduces the thermal effect to a minimum, ensuring that the treatment is gentle for all skin types and without the danger of bruising. The large 5mm spot size, and up to 10 pulses for each second reiteration rate offers fast and effective treatments which depends upon the measure of treatment territory, just 5 – 10 minutes to complete.
What type of Lutronic Q-switched laser is the best?
The safest wavelength for treating skin of all colors is the 1064 nm Nd: YAG laser. Sometimes, in the wake of treating with this wavelength, residual pigment remains, and that is when other wavelengths are required. You also need to search for a laser that has a “tophat” distribution of its pulse energy. What this means is that the energy is equitably distributed across the whole spot size to give a uniform treatment. In the event that this is not the situation, the tattoo or pigmented lesion can be under or over treated in some areas. The shorter duration of the pulse, the better safety profile, and the better results. The short pulse allows for less diffusion of the energy to closer skin so as to leave this skin unaffected. It also allows for greater energy levels on the treated region.
