What does a higher viscosity indicate about a product?

A higher viscosity indicates that a product is thicker. Viscosity refers to a fluid's resistance to flow; the higher the viscosity, the more resistance it has, leading to a thicker consistency. Products with higher viscosity tend to be more gel-like or creamy, which can be advantageous in various applications, including manicures and other beauty treatments, as they may adhere better to surfaces or provide more controlled application.

While it's important to understand the properties of products you use, recognizing that higher viscosity relates to thickness will help you select the right products for specific tasks. The other options address unrelated characteristics, such as dilution levels, pH, or safety, which do not directly relate to viscosity.
