Fractional skin resurfacing is quickly replacing conventional erbium and carbon dioxide skin resurfacing as a means to address deep wrinkles and significant skin damage. While ablative skin resurfacing, which was introduced in the 1980s, requires long healing times, fractional skin resurfacing can achieve similar results with very short downtimes.
Like prior skin rejuvenation techniques, fractional technology is designed to stimulate the production of new collagen in the skin. This occurs over a period of time, as fibroblasts form within the dermis. Coagulated cellular debris is expelled as the skin is remodeled.
However, while non-fractional systems deliver energy uniformly into both healthy and unhealthy tissue, fractional devices are designed to direct photonic energy exclusively to the smaller damaged surface areas while leaving healthy, surrounding tissue intact. These untreated zones, which often include stem cells and melanocytes in the papillary dermis, act as thermal dissipation volumes, allowing for higher energy densities in the treatment spots versus a large spot single exposure. After treatment, the untreated zones then function as healing centers distributed throughout the treatment area. This is particularly important for ablative procedures as it significantly speeds healing compared with a non-fractional approach because these microcolumns can close within one to three days therefore minimizing complications by putting the stratum corneum intact much faster; it also offers a new way to incrementally titrate skin resurfacing treatment from very light to very heavy and enables safe treatment of more delicate areas than was previously possible, such as the neck, chest, arms and hands. Fractional skin treatments allow for the replacement and repair of tissues much deeper than previously possible with traditional laser skin resurfacing.
Depending upon the wavelength of the laser, fractional skin resurfacing may be either ablative or non-ablative, with ablative procedures generally producing a greater degree of improvement. As with non-fractional systems, ablative treatments generally provide a deeper, more significant result in a fewer number of procedures; however, they are often not appropriate for patients with darker skin tones and usually require longer post-procedure healing times (albeit much shorter than healing times for non-fractional ablative procedures). For example, while patients may experience only some slight redness after a non-ablative fractional procedure, CO2 ablative fractional skin resurfacing typically leaves a series of small white spots where the microbeams have penetrated the tissue. After these spots disappear in 10 to 12 hours, the skin becomes red and swollen for several days before drying and flaking off.
Cosmetic Laser Treatments
Cosmetic Laser Surgery is becoming a replacement for traditional cosmetic surgery. Cosmetic laser treatment centers are more common place and offer effective cost effective treatments for the consumer. Cosmetic Laser centers offer many different types of cosmetic lasers that that are in specific cosmetic treatments. Cosmetic laser treatments include; smartlipo, laser blepharoplasty, laser resurfacing, laser scar removal, laser breast reduction, laser breast reduction, laser hair removal, laser eye surgery, laser acne removal, laser tattoo removal, and laser stretch mark removal.
