Given those variables, Dr. Malik gave the following number of sessions that are generally needed with a non-ablative laser: Wrinkles and fine lines: 2-5 treatments depending on severity Acne ...
Fraxel Restore Dual incorporates a combination of a 1,550nm erbium glass laser and an ablative 1,927nm thulium fiber laser. It is commonly used to treat wrinkles, photoaging, surgical scars, and acne scars. [3] Fraxel Repair uses an ablative 10,600nm-wavelength carbon-dioxide (CO 2) laser. This laser is the most aggressive among Fraxel lasers ...
Resurfacing can be ablative, which vaporizes tissue and creates wounds, or non-ablative which keeps the skin intact. Laser resurfacing is usually done with a 2940 nm Er:YAG laser or a 10,600 nm CO 2 laser. Complete resurfacing was first done with a CO 2 laser. Both erbium and CO 2 are used to treat deep rhytides, sun damage and age spots.
An Er:glass laser (erbium-doped glass laser) is a solid-state laser whose active laser medium is erbium-doped glass. Ytterbium (Yb) is sometimes added to these lasers to improve their efficiency. Er:glass lasers emit light in the infrared region of the electromagnetic spectrum, often in the range of 1530–1560 nanometers .
An Er:YAG laser (erbium-doped yttrium aluminium garnet laser, erbium YAG laser) is a solid-state laser whose active laser medium is erbium-doped yttrium aluminium garnet (Er:Y 3 Al 5 O 12). Er:YAG lasers typically emit light with a wavelength of 2940 nm , which is infrared light .
Laser ablation or photoablation (also called laser blasting [1] [2] [3]) is the process of removing material from a solid (or occasionally liquid) surface by irradiating it with a laser beam. At low laser flux, the material is heated by the absorbed laser energy and evaporates or sublimates .
