Q

This process uses a positive pole (anode) or electrode to force positively charged (acid) solutions into the skin without breaking the skin:

A

Cataphoresis

Effects:

  1. Produces an acidic reaction, which can force acidic solutions to penetrate the skin
  2. Slows the blood flow by contracting the vessels to decrease redness or inflammation when applied to simple blemishes on the skin
  3. Hardens tissues, closing pores after facial treatment
  4. Soothes nerves
