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.
Non-ablative lasers come with even less downtime and leave skin looking far less irritated afterward. Ablative: Impacts both the surface of the skin and deeper layers. Non-ablative: Bypasses the ...
Aggressive, heat-based devices work great for some, but not for all. This is what piqued my interest in the “cold” ablative laser device, UltraClear, which launched in 2022.
An Nd:YAG laser drills a hole through a block of nitrile. The intense burst of infrared radiation ablates the highly absorbing rubber, releasing an eruption of plasma. Laser ablation is greatly affected by the nature of the material and its ability to absorb energy, therefore the wavelength of the ablation laser should have a minimum absorption ...
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 .
Erbium-YAG lasers have been used for laser resurfacing of human skin. [2] Example uses include treating acne scarring , deep rhytides , and melasma . In addition to being absorbed by water, the output of Er:YAG lasers is also absorbed by hydroxyapatite , which makes it a good laser for cutting bone as well as soft tissue.
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 ...
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 .
