Laser Hair Reduction

The removal of unwanted hair can be a true challenge for many people. Shaving takes time and can lead to razor burn or cuts, waxing is painful and can lead to ingrown hairs, threading is painful, and tweezing and plucking are labor intensive. With all of these options, the hair will keep growing back. Electrolysis is painful and is very time consuming.

Finally, with the newest technologies, we can offer the best solution for removing unwanted hair quickly and relatively painlessly with Laser Hair Reduction. The heat from the laser will target the hair and the cells in the follicle that are responsible for regenerating new hair growth.

The state-of-the-art GentleMax Pro laser is unique in that it has dual action. It combines an Alexandrite and a Nd:YAG laser, allowing for successful, quick and safe hair reduction in men and women of ALL skin types from the fairest to the darkest skin colors. This laser stands above the others because of its patented “DCD cooling system,” which is a cryogen spray that sprays on the skin milliseconds before the laser pulses. This essentially cools down the skin making the treatment comfortable as well as clean since you don’t have to deal with messy gel or numbing cream. (end paragraph ).

Most patients will need 4- 6 treatments spaced 4-6 weeks apart.  Hair takes 2-3 weeks to shed after a treatment.  During the treatment cycle, avoiding sun exposure and avoiding waxing/plucking/tweezing are advised. Some patients may need “touch up” treatments in a year, several years, or sometimes never again.

Our pricing is competitive. See our price list for details. When compared to waxing, the cost of a package will pay for itself in less than 2 years, and it is well worth it!

The Alexandrite laser of the GentleMax Pro is very effective in removing sunspots.  We can treat solitary spots or large areas of sunspots and sun damage.  The procedure feels like a rubber band snap and is easily tolerable without topical pain medication. In the days following the treatment, the sunspots will darken and form a fine crust, which will then slough off and the underlying skin will continue to lighten over the course of the next 4 weeks. Treatment of sunspots typically require 1-3 visits spaced 4 weeks apart.

Leg and Facial Veins

With the Nd:YAG laser on the GentleMax Pro, we can remove cherry angiomas, small spider veins on the legs and facial veins.  This laser works best on veins that are less than 3mm in diameter. The laser beam will heat up the hemoglobin within the vessel and in turn heat up the vessel wall and ultimately making the vein disappear. The special cooling device on the GentleMax Pro allows this treatment to be performed without numbing medication.Typically, it will take 1-3 treatments for veins, spaced 8 weeks apart.

Skin Tightening

Skin Tightening or Facial rejuvenation is an increasingly popular non-surgical procedure, producing impressive results with minimal downtime. It will reduce the look of fine lines and wrinkles and give the skin a firmer and more youthful look and feel. It can smooth skin texture and treat dull skin or diffuse redness.

In a controlled setting, the heat of the laser will heat the skin and the underlying collagen, causing skin contraction and subsequently new natural collagen growth. During the procedure the skin will feel heat, but no numbing medication is needed. Temporary redness of the skin is expected for up to a couple hours after the procedure. There is really no social downtime and going back to work immediately after the procedure is not a problem. Make up can be reapplied as soon as the redness has resolved. The skin will feel tight immediately and additional tightening will continue to occur for months after the series of procedures. Typically, 3-6 treatments are advised for optimal results.

“I felt so much more confident and relaxed knowing a doctor and NP were performing the service. I had unbelievable results with the laser hair removal procedure after only 2 visits.
