A dropper bottle is a packaging container designed for liquid cosmetics and skincare products, commonly used for serums, essential oils, and medicinal liquids. The bottle is typically made of glass or high-quality plastic, equipped with a precise dropper design that ensures accurate control of each drop, minimizing waste and optimizing usage. Dropper bottles offer excellent sealing, effectively preventing air or external contaminants from affecting the product's ingredients, making them an ideal packaging choice for high-end skincare and serums.
