LASER, which is the acronym for Light Amplification by Stimulated Emission of Radiation, is the the definition of the process by which a certain form of energy is converted into a form of light energy. Lasers are increasingly being used for several cosmetic applications such as treating body aches, removing tattoos and making surgical incisions.
The radiation emitted with the use of Cosmetic Laser Practice operate within a wide range of wavelengths from 100 nanometers up to 10.6 micrometers, as measured on the electromagnetic spectrum. The emission process of laser light is uniquely coherent, collimated and monochromatic. Laser systems are complex in their engineering. The excitation mechanism supplies power to the unit while the Diode Laser Semiconductors work in combination with solid and gas elements to activate the Active medium component in order to produce the laser, using the Feedback mechanism as laser power reflectors.
Laser Tissue Interaction
The different uses of lasers is determined by the type of laser-tissue interaction that occurs:
Photothermal– describes the use of prolonged energy exposure to induce cellular vaporization that results from an increased chromophore temperature. This laser technology is utilized to to remove hair or other unwanted surface level growths.
Photomechanical- employs short pulses of thermal expansion to disseminate the target into small particles by use of acoustic waves. This type of laser treatment is ideal for the removal of tattoos.
Photochemical- emits an penetrable laser that is absorbed in the chromophores, promoting the reduction of pain and inflammation by precipitating a chain of biological reactions. These type of therapy works well for providing photodynamic and Deep Tissue Laser Therapy.
Furthermore, when the laser energy is delivered to the skin there are four specific interactions that occur. When the energy is reflected, the angles of the oncoming beam and the reflective beam are equal. Scattered energy alters the beam and spreads it throughout the tissue. When the energy is transmitted, the wavelengths are penetrated through the tissue with little to no thermal effect. Absorbed energy transmits energy that elevates the temperature of the tissue which causes ablation and coagulation.
Laser-Related Safety Practices
Because of their transformational effect on a dermatologist’s laser practice, there are potentially dangerous hazards associated with Cosmetic Laser Practice such as:
- Electrical Hazard
- Explosion Hazard
- Compressed Gases
- Laser Dyes and Solvents
- Laser Generated Air Contaminants
- Radio-Frequency Radiation Hazards
- Mechanical Hazards Associated with Robotics
These hazards can easily be addresses by employing a Laser Safety Officer (LSO) to oversee the management and risks while ensuring compliance with Occupational Health and Safety, IEC and FDA regulations. Their knowledge of all regulatory standards, regulations, and practice guidelines will ensure you have the necessary engineering, procedural and administrative controls necessary to protect you and your customers.
Importance of Laser Therapy and Effective Identification Analysis
There are several reason why laser therapy is important when addressing high risk skin issues as well as cosmetic issues. First, the photo-bio-modulation component of laser therapy shortens recovery time by increasing the body’s natural regeneration properties. Second, laser therapy offers non-pharmacologic relief from pain. Furthermore, laser surgery delivers precise dosages to each patient, permitting highly accurate treatments.
