Fractional laser photothermolysis (FP) is a form of laser-based skin resurfacing, with several devices on the market, such as Fraxel. A fractional laser delivers laser light to the skin. Hundreds or thousands of laser pinpoints may be used per square inch, leaving healthy skin between the ablated areas.
Fractional laser—best known by the brand name Fraxel—targets wrinkles and acne scars and delivers results few other treatments can. Here's my full review of the procedure, plus input from experts.
Fraxel lasers cause fractional photothermolysis for skin resurfacing. Complications observed in a study of 961 fractional laser treatments included acne and herpes outbreaks. [1] There have also been anecdotal negative accounts of bad scarring and hyperpigmentation following the use of Fraxel lasers. [2]
The population inversion in the laser is achieved by the following sequence: electron impact excites the {v1(1)} quantum vibrational modes of nitrogen. Because nitrogen is a homonuclear molecule, it cannot lose this energy by photon emission, and its excited vibrational modes are therefore metastable and relatively long-lived.
This skin-resurfacing procedure makes use of dermabraders, a rapidly rotating device to exfoliate the outer layer of the skin, [28] thereby promoting the growth of new skin that is smoother in texture. First, local or general anesthesia is employed.
Microneedle radiofrequency is the latest form of delivery and devices include Profound by Candela lasers, Fractora, Intensif, Thermia Ablative RF Fractional by Melorin Group and Genius by Lutronic. Alternative techniques include Laser Resurfacing and certain Ultrasound alternatives. Novel non-invasive versions of radiofrequency delivery include ...

Collagen induction therapy (CIT), also known as microneedling, dermarolling, or skin needling, is a cosmetic procedure that involves repeatedly puncturing the skin with tiny, sterile needles (microneedling the skin).
