What type of electrical current is used in a galvanic facial?

In a galvanic facial, pulsed direct current is utilized primarily because it is effective in inducing chemical reactions in the skin through the process of iontophoresis. This type of current allows for the delivery of active ingredients into the skin by using charged ions, which can enhance product penetration and effectiveness.

Additionally, pulsed direct current can also help in the breakdown of impurities and facilitate a deep cleansing effect, making it especially useful during facial treatments. It contrasts with other types of electrical currents, which may not provide the same chemical interaction with the skin tissues, thus reaffirming the importance of pulsed direct current in achieving specific skin benefits during galvanic facials.
