How can we have deodorant cans that are smaller but still have the same amount in?

Deodorant cans can be made smaller while maintaining the same amount of product by optimizing the design and materials used in the packaging. Advances in aerosol technology allow for more efficient delivery systems, which can reduce the size of the can without sacrificing performance. Additionally, using lighter and thinner materials can also contribute to a more compact design. These innovations help maintain the same volume of product while reducing the overall dimensions of the container.
