The process that utilizes galvanic current to emulsify sebum in the pores is disincrustation. This technique primarily involves the use of galvanic current, which helps to break down excess oil and impurities within the skin. The galvanic current creates a chemical reaction under the skin's surface, leading to the formation of an alkaline solution that effectively softens and liquefies hardened sebum, allowing for easier extraction or cleansing.

Disincrustation is particularly beneficial for individuals dealing with oily or acne-prone skin as it prepares the skin for further treatments, such as extractions or deep cleansing. The technique not only helps in unclogging pores but also aids in the overall exfoliation of the skin, promoting a healthier appearance.

The other options involve different mechanisms and technologies. Microneedling focuses on creating micro-injuries to stimulate collagen production, while laser treatment uses focused light to treat various skin concerns, and neither involves the emulsification of sebum through galvanic current. Desincrustation is simply an alternate spelling for the same technique, reinforcing its significance in skin care.
