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.
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 ...
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 .
Carbon-dioxide lasers have become useful in surgical procedures because water (which makes up most biological tissue) absorbs this frequency of light very well. Some examples of medical uses are laser surgery and skin resurfacing ("laser facelifts", which essentially consist of vaporizing the skin to promote collagen formation). [9]
Laser types with distinct laser lines are shown above the wavelength bar, while below are shown lasers that can emit in a wavelength range. The height of the lines and bars gives an indication of the maximal power/pulse energy commercially available, while the color codifies the type of laser material (see the figure description for details).
Laser-assisted drug delivery (LADD) is a drug delivery technique commonly used in the dermatology field that involves lasers. As skin acts as a protective barrier to the environment, the absorption of topical products through the epidermis is limited; thus, different drug delivery modalities have been employed to improve the efficacy of these treatments.
Carbon dioxide lasers, erbium lasers, and combinations of these are examples of the types of ablative lasers that are used in the resurfacing process. [25] Fractional ablative laser resurfacing procedure. The top outer layer of the skin is removed by the laser, which simultaneously heats the layer of skin lying beneath it. This process ...
In the event of an injury that damages the skin's protective barrier, the body triggers a response called wound healing. After hemostasis, inflammation white blood cells, including phagocytic macrophages arrive at the injury site. Once the invading microorganisms have been brought under control, the skin proceeds to heal itself.
