Laser Technology: Pushing the boundaries of treatment possibilities
Since the appearance of the first medical laser device in the early 1960’s, laser treatments have revolutionised the aesthetic industry.
Aesthetic Laser Technology: A timescale
- 1917: Albert Einstein first described the theoretical concept of LASER (Light Amplification by the Stimulated Emission of Radiation)
- 1960: first functional laser created
- 1992-4: ablative lasers (CO2 and Erbium) first used to treat wrinkles
- 1994-2000: Non-ablative, fractional laser developed with significantly lower risk of infection and shorter recovery time
- 2000: first patent for factional laser technology 2004: first commercial device for fractional non-ablative resurfacing
Types of Aesthetic Laser Technology
- Alexandrite: uses a green gem to penetrate a red spectrum. Used to treat blood vessels, and for hair and tattoo removal.
- CO2 Laser: Carbon dioxide gas is used to generate an infrared light from an ablative laser. Commonly used in laser skin resurfacing.
- Erbium: uses a white metal to produce an infrared laser. Used for skin resurfacing and to minimse the appearance of scars.
- Nd:YAG: uses a crystal to produce near infrared light. Used to reduce brown spots, for tattoo and hair removal. Pulsed Dye: produces a yellow wavelength that penetrates red pigment. Used for treating blood vessels and acne scars.
- Q-switched: short pulses of intense light. Used to treat discolouration and for tattoo removal.
- Picosecond: short pulses of high intensity light. Used to treat discolouration and for tattoo removal. Combination lasers: used to treat multiple indications with the one device.
