Portability: The compact size of 30ml bottles makes them highly portable and convenient for travel or carrying in purses and makeup bags. They take up minimal space and are lightweight, allowing users to touch up their makeup on the go.

Economical: While smaller bottles may seem less cost-effective at first glance, they can actually be more economical in the long run. Users can purchase smaller quantities of foundation, allowing them to experiment with different formulas or shades without committing to a larger, more expensive bottle.
