Desincrustation uses which pole and action?

• A. Positive pole; Open pores to enable penetration of active ingredients.
• B. Negative pole; Open pores and cleanse with acid.
• C. Open pores only.
• D. Negative pole. Open pores; Introduce alkaline preparation into skin; cleanse.

Answer: (D)

Desincrustation relies on using a galvanic current with an alkaline preparation and the polarity that places the electrode at the treatment area as the negative pole. The negative pole drives the alkaline solution into the skin, creating a strongly alkaline environment at the follicle level. This alkaline action saponifies fats in sebum, softening and emulsifying the oils lodged in pores. As a result, the pores effectively open and the debris becomes easier to cleanse and remove. So the key idea is that the negative pole introduces the alkaline preparation into the skin and provides cleansing by loosening sebum, rather than creating an acid effect or simply opening pores without the chemical action.
