The Laurier IBP features a conical tip. The rounded tip of the Probe serves several purposes. It prevents anything other than perfect insertions. It does not allow the Probe to perforate the wall of the follicle. It provides the operator with a distinct signal that the tip of the Probe has reached the bottom of the follicle, thus ensuring proper placement and ease of use.
Because a sharp needle can be inserted into the skin without regard to the follicle, it allows operators to develop poor insertion technique without being aware. Such an operator may initially encounter difficulty when switching to IBP because the tip is rounded and must therefore be placed into the follicle opening. This sense of difficulty very quickly gives way to an "Aha!" moment as skin punctures are replaced by perfect insertions.
The exacting flagpole taper on the blade is our unique signature. No other brand of probe provides a tapered blade.
The taper provides superior flexibilty without sacrificing strength, just like a well-designed fishing pole. The blade flexes smoothly, hugging the curve of the follicle and allowing the tip to settle perfectly in the root area.
The Laurier Insulated Bulbous Probe is a two-piece probe. The stem is fifty-thousandths inch in diameter and one half inch long. This size has been the industry standard for well over 70 years and will fit most push in holders. It is made of brass and plated in gold. The blade is made of high quality 304 surgical stainless steel, custom made to our specific standards. It is attached to the stem by means of a four-indent crimp, which locks the two parts together permanently. The blade is ground to an exacting flagpole taper, exclusive to our probe, for flexibility and strength while the tip is left larger and conical in shape. The blade is then highly polished to a mirror finish and insulated up to, but not including, the tip. Prior to shipping all Insulated Probes are heat sterilized and packed on a protective plastic insert.
The insulation on the blade of the Probe allows a small amount of RF current to escape, thus loosening the hair while concentrating the largest portion of the current at the tip of the Probe. When the Probe is properly inserted the tip comes in contact with the root area allowing the electrologists to use enough current to destroy the root while, at the same time preventing damage to the skin and surrounding tissues. Since damage to the tissue above the root area accounts for the greatest portion of discomfort associated with epilation treatments, a properly insulated Probe can greatly increase client comfort.
The images at right are actual microphotographs taken by J. Laurier in 1970. They show a side-by-side comparison of a bare wire needle versus the Laurier Insulated Bulbous Probe at the same power setting. The IBP concentrates the current at the tip, where the hair root would be. The bare wire needle releases current all along its length, unnecessarily damaging the surrounding skin and lessening the effect at the root where it is most needed.
To demonstrate the coagulation pattern shown and described above, or to test the needle you're using at present, discharge the Probe or needle into a metal teaspoon of egg white, held in the hand to provide capacitance. The videos below show this experiment using a Laurier Insulated Bulbous Probe versus an uninsulated one-piece probe at the same power setting.

Because of the intense concentration of the heat at the tip of the Probe during use, materials from the skin tend to adhere more so than you have been accustomed to with a bare needle or one whose insulation is transparent to RF current. This adherence is how you can tell that you are getting effective treatment. It indicates that sufficent heat has been applied at the follicle root to cause coagulation.
When using the Insulated Probe, coagulation does take place at the tip of the probe and adherence of material is unavoidable. It is, therefore, imperative that the Probe be cleaned often by pinching in a sterile cotton ball wet with sterile water, alcohol, or Zephiran Chloride solution. Unless this is done often the Probe will build up dried oil, etc, and become difficult to insert. The Laurier Insulated Bulbous probe may also be sterilized by dry heat or autoclave as required by CA and NJ law among others.
