What Are Non Ablative Lasers?
A non-ablative laser generates beams of coherent light using a very narrow range of wavelengths.The light beams selectively target and heat the water chromophore in the skin. As a result the temperature of the tissue rises which stimulates neocollagenesis. There are various forms of non-ablative lasers and they typically have a good water absorption mechanism that impacts the water chromophores but does not cause ablation. Fiber lasers are commonly used for non-ablative treatments. A fiber laser is an optical fiber that is “doped” with elements designed to generate a laser beam at the desired wavelength. Erbium Glass is a typical fiber laser used for this purpose.
How Does A Non Ablative Laser Work?
The non-ablative laser uses a wavelength that does not cause the water in the tissue to evaporate (ablate) but rather the laser energy heats the tissue in a controlled manner. The rise in temperature stimulates neocollagenesis, a process in which new collagen is produced by the body. Collagen is a fibrous protein that is responsible for giving the skin its elasticity and suppleness. By producing new collagen the skin regains is youthful appearance. Since the treatment does not involve tissue evaporation or ablation, treatment downtime is significantly reduced, which is also why it is preferred over ablative treatments by many patients.
The Lumenis Non Ablative Solution
The ResurFX™ laser is the only true fractional non- ablative technology. Unlike other fractional technologies, ResurFX™ only needs one pass to be effective, saving time and protecting the patient’s skin. ResurFX™ uses a 1565nm fiber laser and an advanced scanner, which enables the user to choose from more than 600 combinations of shape, size and density options, for optimal treatment results. The ResurFX™ has state-of-the-art CoolScan™ scanner for non-sequential scanning. The CoolScan™ scanner uses a proprietary algorithm that controls the placement of each fractional spot. This protects the tissue from heat accumulation and overheating. Moreover, the ResurFX™ handpiece is equipped with continuous contact cooling to increase patient comfort during treatment.
