What is the primary effect of the desincrustation process?

The primary effect of the desincrustation process is that it produces alkali at the cathode. This process is typically used in facial treatments, especially during galvanic treatments, where a direct current is passed through the skin. The electrical current helps to break down sebum and impurities within the pores, facilitating their removal. Specifically, when an alkaline solution is generated at the cathode, it helps to saponify the oils and other impurities, making them easier to extract from the skin.

While the other options may reflect some benefits associated with skin treatments, they don't capture the fundamental chemical action of the desincrustation process. For instance, enhancing blood circulation is a result of improved skin health but not the primary effect of desincrustation itself. Additionally, while toxins may be removed as a secondary result, this is not the core mechanism of action. Similarly, hydration can occur due to different treatments but is not specifically tied to the desincrustation process. Thus, the production of alkali at the cathode is central to the efficacy of desincrustation.
