Palomars Starlux 2940 vs. C02 Ablation Lasers

Cosmetic dermatology, plastic surgeons, medical spas and their patients will be hearing more and more about fractional skin resurfacing technologies like ActiveFX, DeepFX, Starlux 1540, Starlux 2940, Fraxel Repair.

To grasp the significance of these new laser skin resurfacing devices some minor understanding of the technologies of cosmetic laser skin rejuvenation treatments as well as older cosmetic laser skin treatments is a good start.

Fractional Laser Skin Resurfacings Previous Technologies

Fraxel was the first non ablative fractional laser for the cosmetic medical market. It’s been upgraded since first being introduced and has been followed by a number of other fractional laser skin resurfacing technologies including the DeepFX and ActiveFX from Lumenis and the Starlux 1540 and Starlux 2940 from Palomar Medical.

Fractional laser skin resurfacing is new area of medicine that intersects cosmetic dermatology and traditional plastic surgery. Rapid advancements and new breakthroughs in these types of cosmetic medical technologies are occurring frequently and are fueled by an aging population of patients. The benefit for these patients is a rapid increase in the effectiveness of fractional laser treatments and less down time and potential side effects.

Fractional laser technologies new cosmetic applications are expanding into related areas like skin tightening treatments, where fractional treatments compete with radio frequency (RF) treatments like Thermage, and will eventually move into fat and cellulite treatments and removal.

Old, full face CO2 laser resurfacing treatments to treat wrinkles using the Ultra pulse CO2 laser, now compare poorly when faced with new fractional laser technologies. CO2 laser resurfacing created a very traumatic “burn wound” that literally vaporized the top layers of the dermis and took many months of recovery in addition to the need for general anesthesia. The additional problem of the skin turning white with hypo pigmentation as the pigment cells were destroyed fair poorly as well. Because of the risk of negative side effects, few patients choose this procedure.

The Newest Fractional Skin Resurfacing & Rejuvenation Technologies

Within the last few years, cosmetic Fractional Skin Rejuvenation or Fractional Laser Skin Resurfacing has evolved and eliminated many of the existing technologies shortcomings. The erbium laser used in the newest Starlux is ‘fractionated’ into tiny micro-lasers, treating only a small portion of the skin (think tiny pin pricks) and leaving surrounding skin intact, greatly improving healing.

These ‘fractionated’ treatment areas are referred to as micro-treatment zones and cause just enough injury to the layers of the dermis to trigger new collagen production and stimulate the replacement of collagen damaged by aging and sun exposure. This production of new collagen ‘fills in’ or ‘plumps’ the underlying dermal tissues and smoothes wrinkles. The surrounding, untreated skin speeds the healing process to a mere 3-4 days. Since most of the pigment cells remain intact, hypo pigmentation is effectively prevented.

Starlux 1540: Palomars New Fractional Non-Ablative Laser Resurfacing Technology

The Fraxel and Starlux1540 are non ablative lasers (ablate means to “surgically remove) which means that the skin is not removed by the laser, rather the laser beam instantly heats the skin, causing inflammation and new collagen growth.

Results for wrinkle removal and skin tightening are less dramatic than with ablative lasers, but the benefit of reduced recovery time and fewer side effects are mean that non ablative laser treatments are often the patients first choice.

Starlux 2940: Fractional Ablative Laser Resurfacings Future

New fractional ablative lasers have recently been developed that provide the benefits of fractional treatments (less down time and reduced complications) as well as the benefits of ablative skin resurfacing (better wrinkle removal and facial rejuvenation).

These newer fractional ablative lasers remove the tissue in the micro treatment zone rather than just heating it as is done with the old Fraxel and the Starlux 1540.

The benefit of this new fractional laser ablation is that a greater amount of wrinkled and sun damaged skin can be removed than with the older laser technologies, and a better medical result is achieved. There is some minor increase in recovery time with redness for around 5-6 days. Still, the Starlux fractional ablative lasers require much less recovery time than the old non fractional erbium and CO2 ablative lasers which actually burned off the top layers of the patients dermis.
