High radio frequencies represent a relatively new, but very safe method of permanent removal of hairs, hyperkeratosis, capillaries and other imperfections on the skin.
Radio frequency affects the hair follicle by creating magnetic field inside the follicle and initiating strong local warming which the patients feels like prickling. Local temperature triggers hair follicle coagulation. Depending on the hair root, after several treatments hair is completely and permanently destroyed, which prevents it from growing.
Active electrode may be a needle or a tweezer. As hair is keratin structure similar to wood, and wood is an isolator, hair is not a good conductor and thus complete destruction of hair by RT via tweezer is absolutely impossible. There are several electrodes in the form of:
1) small hair that looks like a moss. This type of hair is short, colorless and its root is at 1-2mm in the dermis
2) medium hair with pigmentation is a little bit longer and its root is at 3-4mm in the dermis
3) large hair is long, thick and dark, and its root is at 3-4mm in the dermis., i.e. public hair, armpit hair and scalp hair.

There are 3 phases in hair growth cycle: anagen (phase of growth) when the follicles are the deepest, catagen (phase of cessation) when the root is not so deep and telogen (rest phase) when the follicle is almost at the surface of the skin.

The needle transmits the dosed energy on the level of hair follicle. There are various needle-based electrodes: stainless surgical steel needles are used at patients with healthy skin who handle electrolysis well. 24 carat pure gold needles are used at patients with hypersensitive skin which is subject to frequent allergies. Gold needles prevent skin irritation, while redness and mild swelling withdraw very quickly after epilation with this type of needle.

Thermally isolated needles are covered with insulating material, thickness of 1 micron, in a way which makes only the top of the needle active on the level of hair follicle. This type of needle allows longer electroepilation (ED) sessions, as the intervention is painless- depending on the treated region and currency level, the patient has a sensation of very mild prickling or feels nothing at all. Needle diameter is from 0,1 to 0,8mm, flash exposition time from 0,002 to 0,006, which depends on the treated region and patient’s gender. Common characteristic of these needles is mildly sharp but polished top which can penetrate the follicle, i.e. opening on skin surface, into hair channel without damaging the surrounding tissue. The needle follows the direction of the hair, reaches its root and immediately burns weak roots. Physiological saline can be applied to the skin for better conductivity.

The device has a foot pedal for directing current into active electrode, i.e. needle, as well as sound signal which indicates currency duration, i.e. flash per hair. If a radio device is turned on during the protocol, one can have a live coverage of ED on specific radio frequency.

Even though female population is facing the problem of unwanted hair growth, majority of women hesitate to remove hairs as they believe they will be longer and thicker after the treatment. If one decides to try contemporary ED method under the supervision of professional therapist, there is no reason for fear. Moreover, depilation is to be an integral part of male and female care, as, in majority of cases hairs represent esthetic, hygienic and medical problem.

Needle epilation requires many years of experience, steady hand and sharp sight of the expert as the needle is placed directly in hair follicle. Unprofessional epilation results in damaging the surrounding tissue without destroying the hair. Consequences of unprofessional intervention may be burns, marks and scars.
