Electrolysis comes with a number of risks and potential problems. On the practical side, electrolysis is time-consuming; it requires a technician to destroy hairs one at a time. Though treatment sessions are typically short, your first treatment may only destroy 15 to 50 percent of your unwanted hair [source: Leortec]. It could take a year of treatments to eliminate all your unwanted hair, which may take a hefty chunk out of your pocketbook [source: Bouchez].
Though electrolysis doesn't involve outside chemicals or burning lights, it's associated with a number of other negative side effects. In some cases, you could feel pain during treatment. Your technician might apply a numbing cream to the skin an hour before treatment to help reduce that pain. Scarring and temporary inflammation can also occur, though it's unlikely [source: Bouchez].
You should not choose electrolysis if you have a pacemaker, as a direct current could heat up the pacemaker's metal plates [source: Barba]. Electrolysis is also not recommended for people with rosacea, since the skin is so easily irritated.
Finally, though electrolysis is good at eliminating the curved hairs of people of African descent, the method has the potential to change their skin color. Areas of the skin treated by electrolysis may become lighter or darker than other parts of the skin. This change is most noticeable in darker-skinned people [source: Bouchez].
