Bottles come in a diverse array of shapes, sizes, materials (such as glass, plastic, and metal), and designs to cater to different product types and brand aesthetics. They can be equipped with various types of dispensers, including pumps, sprayers, droppers, and flip-top caps, depending on the viscosity of the product and the desired application method. Key uses include: • Serums and Lotions: Often packaged in smaller bottles with pump or dropper applicators for precise, hygienic dispensing. • Cleansers and Toners: Typically found in larger bottles with pump or flip-top caps for easy application. • Foundations and Liquid Makeup: Bottles with pump dispensers are popular for their convenience and control over product quantity.
