Laser Treatments Q & A


Lumenis FX™ Fractional CO2 Laser treatment is used for:

  • Coarse & Fine Wrinkles
  • Laser Skin Resurfacing
  • Lentigos & Age Spots
  • Skin Laxity
  • Skin Pigmentation Problems

The CO2 Laser has long been considered the “gold standard” device for laser skin resurfacing of the skin in an effort to correct wrinkles, laxity, scars, and pigment problems. Although effective in the right hands, the lengthy downtime and somewhat narrow safety window associated with this procedure limited this laser’s widespread use….until now. 

How Lumenis FX™ Fractional CO2 Laser Works 

Rather than affecting the entire skin, the Lumenis UltraPulse® CO2 laser ablates only a fraction of the skin surface, allowing bridges of non-affected tissue to stimulate rapid healing. This new approach to fractional laser skin resurfacing is more comprehensive, and considerably more effective, than previous fractional systems utilizing other laser systems (i.e. Fraxel re: fine/re:store™, Palomar StarLux®).

Are there any Lumenis FX™ Fractional CO2 Laser Side Effects? 

In dozens of controlled clinical trials with the Lumenis FX™ CO2, the incidence of unwanted side effects was extremely rare. To date, the two most feared complications of traditional CO2 laser resurfacing, depigmentation of the skin (white spots) and scars, have not been reported in any patient. 

However, patients who are treated with the Lumenis FX™ are overjoyed with the laser’s effectiveness. Several clinical trials have shown its superiority in the treatment of coarse and fine wrinkles, skin laxity, dyschromia and sun spots, rhytids, and overall skin aging. Simply put, there is no procedure on the market, either laser or surgical, that can deliver the results of fractional CO2 resurfacing with the Lumenis FX™.

Lumenis FX™ Fractional CO2 Laser Treatment Levels 

Treatment can be tailored to each patient’s needs, with regard to both clinical indication and severity. Dr. Knight can adapt your treatment to your specific problem and tolerance for downtime.

Deeper wrinkles and scars require treatment with the DeepFX™ protocol; the fractional CO2 laser penetrates deep dermal collagen but there is a higher percentage of untreated skin, enabling fast healing.

The ActiveFX™ protocol treats sun spots, dyschromia, and light wrinkles; a larger spot size but limited skin penetration also promotes rapid healing. 

Lumenis FX™ Fractional CO2 Laser Results

 Results are both instant and long-term. Only one treatment is required. Each pulse of the laser removes a column of tissue, eliminating pigment problems and causing skin tightening. Deep skin heating further promotes collagen contracture and long-term new collagen formation. In addition, the Lumenis FX™ can treat areas off the face, such as the hands, neck, and chest.

What to expect after Lumenis FX™ Fractional CO2 Laser treatment 

Downtime ranges from two to five days, depending on the treatment protocol. In all cases, most of the superficial skin peeling is resolved by five days, leaving only a slight pinkness. Over the next six months, there is a progressive skin tightening, helping to correct fine and deep wrinkles, scars, and laxity.

Candela® VBeam Laser

Candela® VBeam Laser is used to treat:

  • Facial redness and blood vessels
  • Fresh surgical and traumatic scars
  • Acne Scars
  • Resistant warts
  • Port-wine stains
  • Vascular birthmarks

The Candela® VBeam Pulse Dye laser’s ability to treat a wide range of skin conditions makes it the most utilized laser in our practice.

The Candela® VBeam Pulse Dye laser is a “visible light” laser; by delivering an intense but gentle burst of yellow light into the skin, its energy is absorbed by hemoglobin in blood vessels. The body then removes these blood vessels during the natural healing process.

How Candela® VBeam Laser Works

By using an inherent property of lasers called selective photothermolysis, the Pulse Dye laser targets vessels while sparing other skin structures such as pigment cells (melanocytes), hair follicles, etc. The incidence of dark spots, white spots, and scarring is extremely low. Additionally, the Candela® VBeam uses dynamic cooling of the skin to further enhance the safety and comfort profile. 

In some cases, we combine Candela® VBeam Pulse Dye laser treatment with a topical photosensitizing agent (aminolevulinic acid)) that enhances the laser’s properties: this is called photodynamic therapy or PDT.
