What type of water should be used in the Skin Wellness Pro to avoid mineral buildup?

The use of distilled water in the Skin Wellness Pro is essential for preventing mineral buildup because it is water that has been boiled to remove impurities and then condensed back into liquid form. This process eliminates minerals and other contaminants that could otherwise accumulate in the equipment over time, leading to potential clogs or malfunctions.

In contrast, purified water might still contain certain trace minerals even after filtration, which makes it less effective for this specific purpose. Spring water, while generally considered clean, often contains a variety of minerals that could contribute to buildup. Similarly, mineral water is explicitly high in various minerals and should be avoided entirely if the goal is to maintain the equipment in optimal condition. Thus, distilled water is the best choice to ensure longevity and functionality of the Skin Wellness Pro.
