The spray machine that carries plant extract, herb teas, skin fresheners, and astringents to the face in a fine mist is called:

The correct answer is the pulverizer. This device is specifically designed to create a fine mist from various liquids, including plant extracts, herb teas, and skin fresheners. The pulverizer uses a mechanical process to break down these liquids into tiny droplets, allowing them to be evenly distributed over the skin. This fine mist application is beneficial for delivering hydrating and soothing ingredients directly to the facial skin, enhancing treatment effects and providing a refreshing experience for clients.

The atomizer, while a similar device used to create a spray, typically refers to smaller devices used for fragrance or very fine sprays rather than the more substantial mists needed in esthetics. A humidifier is designed to add moisture to the air, not specifically to spray liquids onto the face. The vaporizer is generally used for generating steam or vapor but does not refer specifically to the process of creating a fine mist from plant extracts or skin products. Thus, the pulverizer is the most accurate term for the machine described.
