Facial and scalp treatments can utilize various methods and techniques in order to achieve their desired results. Among these methods, voltage, frequency, and current all play important roles. In particular, current is a term that refers to the flow of electrical charge, and in the context of facial and scalp treatments, it helps to stimulate muscles and skin cells. Out of the options provided, conduits and circuits are incorrect because they only refer to the path that electrical current travels through, rather than the actual type of current used. Wavelengths also do not apply as they refer to the distance between electrical waves or pulses rather than the type of current. The correct term for the different types of current used in facial and scalp treatments is referred to as modalities. These modalities can include direct current (DC) or alternating current (AC), both of which provide unique benefits in different types of treatments.
