Which type of electrical current is used to close the pores?

The type of electrical current used to close the pores is galvanic current. This form of current operates by using a direct current to facilitate various skin treatments. In particular, galvanic current is effective for iontophoresis, which helps in penetrating product ingredients into the skin and can also assist in tightening and closing pores after a facial treatment.

When applying galvanic current, the positive electrode is typically used to create a tightening effect on the skin, which helps to minimize pore size. This direct current stimulates the tissue while optimizing the delivery of active substances, enhancing overall skin appearance and health.

In contrast, alternating current and high frequency current have different applications. Alternating current changes direction periodically and is found in devices that focus on varying skin stimulation, while high frequency current generates ozone to treat conditions like acne and improve overall skin firmness but does not specifically target pore closure as effectively as galvanic current.
