In response to the ever-increasing demand to remove unwanted hair on virtually any body area, the ability to offer superior results to the widest variety of patients is crucial. The LightSheer^™ Diode Laser System delivers on the promise and has become the most popular laser hair removal device worldwide. Offering a unique combination of laser parameters and patented ChillTip™ protection, the LightSheer family of diode laser systems represents quintessential simplicity in a state-of-the art package.

Multi-Application Capability

In addition to clinical documentation of the LightSheer's efficacy with hair removal, it is also FDA cleared for the treatment of leg veins, providing the operator with multi-application capabilities.

Lasers have been used for hair removal since 1995, but few have had properties that are also effective in treating leg veins. This dose-response study at Wellman Laboratories on 25 patients with 200 treatment sites has determined parameters for an 800 nm high-powered diode laser. It has also resulted in recommendations for patient selection and a treatment protocol. Patients presenting with leg vessels between 0.4 and 1 mm have been shown to respond to laser treatment, with the results improving with the number of treatments and with time after treatment.

How It Works

The key to successful hair removal is destroying the entire follicle, down to the bulb and its germinating centers, while preserving surrounding healthy tissue. Destroying the hair follicle during its active growth cycle is another key to producing long-term hair reduction. Consequently, multiple treatments scheduled several weeks or months apart are typically required to achieve optimal results.

Lasers and IPL light sources gently remove unwanted hair based on the principle of selective photothermolyisis. This refers to the process whereby light energy causes thermal injury to the hair follicle. The light penetrates through the skin and is absorbed in the target pigment (melanin) found in the hair shaft. This energy absorbed in the shaft causes the temperature to reach a sufficiently high level in the hair follicle so that the targeted hair structures are destroyed and regrowth is inhibited.

The LightSheer™ Diode Laser System, with its unique combination of laser parameters, penetrates tissue to destroy the base of the hair follicle and stunt hair regrowth. At the same time, the LightSheer system's aggressive cooling provided by the ChillTip hand piece minimizes potential collateral epidermal damage caused by light absorption by melanin in the epidermis. This patented ChillTip™ combined with efficient, reliable, high-power diode technology, makes the family of LightSheer lasers the most advanced hair removal system available.

Frequently Asked Questions

Q: How does the LightSheer^TM Diode Laser System work?

A: The system emits near-infrared laser light that is absorbed by the pigment located in the hair follicle. The laser is pulsed, or turned on, for only a fraction of a second. The duration of each pulse is just long enough to damage the follicle, while the system's unique, patented contact-cooling handpiece, the ChillTip^TM, helps protect the skin by conductive cooling during the laser energy delivery.

Q: What advantages does the LightSheer have over other laser hair removal systems?

A: The LightSheer Diode Laser System was designed from the ground up for laser hair removal, so it has the wavelength, fluence, pulse width, and active epidermal cooling system - the ChillTip^TM ideally suited for laser hair removal. The system is small, compact, and (in some models) portable, so it fits well into virtually every type of existing practices. The system's solid state construction makes it durable; it's state-of-the-art user interface makes it easy to use. Finally, Lumenis^TM has been in the business of making medical and cosmetic lasers for more than 30 years, so we've been able to develop unparalleled service and support—from our extensive training and practice building resources to our stand-alone systems' 24-hour replacement service. No other hair removal system offers the same combination of product excellence and customer service and support.

Q: Why should I use the LightSheer Diode Laser System rather than the methods I've been using for years?

A: The LightSheer Diode Laser System's design provides for enhanced comfort during treatment, minimal risk of infection, speed and accuracy. Since the system uses a unique cooling handpiece, it minimizes skin irritation that other methods may create. Since it is non-invasive (no needles to penetrate the skin), the risk of introducing bacteria into the skin is reduced. Because the system is fast, it allows for larger areas to be treated, considerably increasing the efficiency of the hair removal process, which allows more patients to be treated during a typical day. Finally, the LightSheer Diode Laser is a precise instrument that can be adjusted to damage only the hair follicle while minimally affecting the surrounding skin.

Q: Does the LightSheer work on tanned or different skin colors?

A: The LightSheer diode laser system safely and effectively treats all skin types (Fitzpatrick Skin Types I-VI) as well as tanned skin. For darker skin types and people with tans, appropriate fluences are generally lower and appropriate pulse widths are generally longer to prevent damage to the epidermis. Using the appropriate treatment parameters, however, people with all skin types can benefit from laser hair removal with the LightSheer.
