What substance is emulsified or liquefied during the desincrustation process?

1. Dead skin cells

2. Makeup residue

3. Sebum and debris

4. Moisturizers

The correct answer is: Sebum and debris

During the desincrustation process, sebum and debris are emulsified or liquefied. This procedure is typically performed using galvanic current to facilitate the chemical reaction in the skin. The high-frequency electrical current helps to break down the oil, dirt, and other impurities that are trapped in the pores, effectively softening and loosening them for easier removal. The focus of desincrustation is primarily on the combination of sebum—a natural oil produced by skin glands—and debris, which may include dead skin cells, dust, and environmental pollutants that contribute to clogged pores. By targeting these substances specifically, desincrustation aids in deep cleansing the skin and preparing it for further treatments. Other options such as dead skin cells and makeup residue may be removed during different processes or treatments but are not the primary focus of desincrustation. Moisturizers, on the other hand, are typically applied after cleansing and do not undergo emulsification or liquefaction during this specific procedure. Thus, identifying sebum and debris as the substances involved during desincrustation clarifies the purpose and effectiveness of this technique in skin care.
