Laser Photorejuvination

Non-ablative photorejuvination and skin-tightening with CO2 laser (DEKA)


Laser Photorejuvination NaplesWater represents the main component of the skin (approximately 77% of its totale volume) and has therefore a key role in the laser-tissue interaction. CO2 lasers (10,600 nm) and Er:YAG lasers (2,940 nm) emit light in the far-infrared spectum where water-molecules absorption of the the radiation prevails on skin penetreation. The goal of a surgical laser (both pulsed or continuous) is to perform ablation with the least thermic damage.

Possibile applications of surgical lasers range from resurfacing treatments to vaporization of a number of benigne skin lesions, not to mention fractional photothermolisis, another recent and interesting application of these lasers.

This technique determines a series of microscopic and poorly-ablative thermic damages at various depths (microablative resurfacing). The fractional scanning performs points of tissue penetreation, separated by points of untouched skin. Thermic columns are therefore created, which diffuse heat to the surrounding areas, generating sudden shrinkage and collagen denaturation, with subsequent neocollagenogenesis.

Thanks to the special Hi-Scan DOT scanning system, the emission of CO2 laser takes place on a dot-per-dot basis (hence the name of the laser system), generating microareas of thermic damage alternated by intact tissue. In the treated microareas, the controlled transfer of heat creates immediate tissue shrinkage and neocollagenogenesis is therefore stimulated.

The areas of untouched tissue between the treated ones allow a more rapid tissue repair with a dramatic decrease in recovery time and persistence of post-treatment erythema.
