BEAKER

A “beaker cosmetic” refers to using laboratory-style glass beakers, typically heat-resistant borosilicate, for mixing, measuring, and blending cosmetic ingredients like essential oils, serums, and lotions, offering precise volume marking, easy pouring (spout design), and a neutral material that doesn’t affect product chemistry, common in DIY beauty or small-batch production. It’s essentially lab glassware adapted for beauty formulation to ensure accuracy and purity.
