How To Understand Candela Laser Treatments
Candela is the worldwide leader in light-based aesthetic therapies, with branches located in the United States, Europe, and Asia. For the past four decades, Candela has been revolutionizing the skin care industry by creating safe and efficacious lasers used by countless dermatologists and aestheticians in over 86 countries and supported by more than 300 peer-reviewed scientific journals.
To understand how lasers serve their important functions in skin care, it might be of interest to discuss a little about lasers. The laser is an acronym that stands for light amplification by stimulated emission of radiation. The most typical characteristic of laser light is its coherence – that is to say, that light waves in lasers are in step and that laser is emitted in a narrow, non-diverging ray. Hence, lasers are often represented as bright, narrow beams of light.
Laser light is generally emitted in a particular wavelength of light (usually in the nanometer [nm] range), which is inversely proportional to the strength of the laser. A laser with a very short wavelength possesses more energy than one with a longer wavelength. Aside from the wavelength, another measure of a laser’s strength is its light intensity or capacity for illumination, which is represented in terms of a lumen (lm) or, quite interestingly, a candela (cd).
Lasers have uses that transcend disciplines. They are used in engineering for accurate measurements and 3D, or stereo, representations. In health care, they have found uses in ophthalmology and cardiac surgery and, of course, in dermatology.
The principle of laser therapy in dermatology is to destroy target cells without damaging the surrounding tissues. A particular tissue strongly absorbs a certain wavelength of light that is intrinsic to a particular laser system. When the targeted tissue absorbs the wavelength, the cell then heats up and dies.
Candela lasers are used in the treatment of a variety of skin conditions including treatment of acne and acne scars, reduction of fine lines and wrinkles, permanent removal of hair, lightening of pigmented lesions and tattoos, and treatment of diseases such as psoriasis and rosacea.
Candela lasers are specialized in performing particular tasks. The GentleLASE system is a 755 nm laser used primarily for the permanent, safe and efficacious removal of unwanted hair. Each GentleLASE laser is equipped with a Dynamic Cooling Device that makes the laser treatment very safe and comfortable for the patient. The Candela GentleLASE system is also very versatile, capable of lightening various darkly pigmented lesions and reducing wrinkles and fine lines.
For the meticulous aesthetic healthcare professional looking for a very versatile system, Candela also offers the GentleMAX System that combines the hair-removal capabilities of the GentleLASE system and the unsurpassed capabilities of the GentleYAG system in reducing leg veins, facial veins, and wrinkles. The GentleMAX is the first multiple wavelength workstations uniquely designed to address the most common problems in aesthetic medicine and dermatology. Truly, Candela has the right laser for whatever your practice needs.
