The term "airbrushed" has two possible meanings.
1) In a general sense, airbrushed refers to something that is smoothed out or made more polished through the use of an airbrush tool. This can be applied to various mediums such as artwork, photography, makeup, and even cars. The airbrush sprays paint or other substances in a fine mist, allowing for precise and detailed work without brushstrokes or imperfections.
2) In a more specific sense, "airbrushed" can refer to the practice of retouching photographs using an airbrush tool to remove blemishes, wrinkles, or other unwanted features from subjects in order to create a flawless appearance. This is often used in advertising and fashion photography to make models appear more perfect than they may actually be.
