What does non-porous mean in terms of materials?

Non-porous materials are those that do not have any pores, openings, or gaps in their structure, making them unable to absorb liquids. This quality is significant in various applications, especially in aesthetics and hygiene. In the context of lash extensions, for example, non-porous surfaces are crucial because they do not harbor bacteria and are easier to clean, which minimizes the risk of infections and ensures a safe application process.

When a material is classified as non-porous, it means that it can withstand exposure to substances like water or other liquids without allowing them to seep in. This characteristic helps maintain the integrity of the material over time and ensures that products applied on or with that material do not penetrate or alter its properties.
