Step-by-step explanation:
An automated Air Brush tan is a method of applying a tanning solution to the body using a machine. This technique utilizes a spray gun or a booth that releases fine mist of tanning solution, which contains active ingredients like dihydroxyacetone (DHA) that react with the skin's surface to create a temporary tanned appearance. It's a popular alternative to traditional sunbathing or tanning beds, providing a more uniform coverage without UV exposure.
