The correct therapeutic ablation depth is the minimum depth needed to achieve the desired clinical result, whether it is for the effacement of rhytids, removal of photo-damage, or collagen tightening.
Generally, laser resurfacing is performed by treating the area completely, until the to-be-removed lesions have been ablated or until punctate bleeding appears, which indicates the papillary dermis has been reached.
At the papillary dermis level a maximum therapeutic effect is achieved with a minimum risk of side effects. Continuing to treat deeper than the papillary dermis has minimal clinical benefits, while the potential of complications and side effects may even exponentially increase.
With clinical experience it is advisable to select laser treatment settings that will give the desired result in 2-4 passes. Visual clinical end-points for the three ablative regimes.
The sequential laser-layering techniques have been successfully used in PWS and more recently in antiaging with good clinical results.
Since temperature seems to play a key role in stimulating neo-collagen and extracellular matrix production, we thought to sequentially combined two different laser wavelengths (1064 nm Nd:YAG and 2940 Er:YAG) in a three-step layering technique.
The Nd:YAG laser perfectly complements the Er:YAG laser ablative action with the ability to penetrate deeply into the skin to create thermal effects without damaging the skin surface.
Why Does Vancouver Medi Spa Use VSP Pulses Than Other Technology ?
Compared to conventional Nd:YAG technologies, this laser system has the VSP pulse which creates virtually instantaneous temperature increases that are limited to the targeted structures only.
To provide fractional treatments, this technology has developed unique Pixel Screen Technology (PST) that divides the basic Er:YAG treatment beam into parallel beam pixels based on the PST which has been compared to other fractional technologies that allows the laser beam quality and parameters within the pixels to remain unchanged compared to the basic beam properties
This enables the practitioner to perform all nine basic VSP Er:YAG ablative treatments and the smooth treatment with fully clinically tested laser parameters.
The only difference is that the skin is treated with pixelated Er:YAG laser beams. Other fractional technologies use focused beams with modified pulse fluences in the fractional spots and therefore with modified and relatively uncontrolled thermal treatment modalities.
The PST ensures that the laser fluence in each pixel is exactly as it would be with a standard Er:YAG laser hand piece.
This enables the practitioner to perform nine basic ablative and one non-ablative treatment at fully clinically tested laser parameters.
PST provides another dimension in the treatment of various skin conditions, avoiding some of the adverse effects of ablative laser procedures while improving the limited efficacy of the non-ablative treatments. No unnecessary energy is deposited into the skin.
