Once the germ cells are destroyed, that hair follicle cannot produce another hair. Proprietary gels, creams and solutions work in conjunction with this equipment and are vital to successful results. Water content of each hair follicle determines whether a sufficient amount of electrical current will be conducted through the hair. Without effective products, conductivity is limited, making permanent removal very time consuming. Some manufacturers state that the current is dissipated in the skin itself with these gels and that they cannot possibly aid in conducting current to the hair root.
All hair removal takes more than one or two treatments.
This method, not unlike needle electrolysis, does not kill all the hair follicles the first treatment. However, in blind clinical studies, results were shown to match, and sometimes exceed, results achieved with needle epilators. Manufacturers stress that this method does not require as much skill on the part of the practitioner as needle methods because the hair root is always located on the end of the hair which is held in the tweezers and eliminates probing for it. These devices, like needle epilators, are Class I devices by FDA classification but unlike needle epilators, all manufacturers must submit clinical test results to the FDA for review before they can market their equipment as permanent hair removal devices. A 510k must be submitted to the FDA for safety review and clinical studies must be submitted prior to marketing as permanent.
