The negative pole during device treatment is associated with which effect?

• A. Increased blood flow
• B. Decreased blood flow
• C. No effect
• D. Increased sebum production

Answer: (A)

The main idea here is how polarity in galvanic device treatment changes skin response. Using the negative pole (the cathode) on the skin creates an alkaline environment at the treatment site and provides mild electrical stimulation. This combination tends to cause superficial blood vessels to dilate, increasing microcirculation in the area. So, you get more blood flow under the negative pole, which supports nutrient delivery and product uptake. This is not about reducing blood flow or having no effect, and it isn’t about increasing sebum production. In fact, the negative pole is more associated with stimulation of circulation and, in practice, desincrustation occurs through the alkaline environment to soften and remove sebum, not to boost its production.
