The main job of the crew makeup artist is to put on makeup for the actors to help them better complete the role-play. Their work involves applying makeup to actors, removing makeup, adjusting skin tones, retouching facial details, and much more.
Whether the makeup artist's job is stable
For crew makeup artists, the stability of the job depends on the number and size of the crew. Generally speaking, large crews will have more characters who need makeup, so makeup artists will also be in greater demand. However, the crew's working hours are not fixed, and filming may need to be done late at night or early in the morning, which is also a challenge for makeup artists. In addition, if the crew stops filming or changes roles for various reasons, the work of the makeup artist will also be affected. 
Conversely, some small crews may not have as many characters to make-up, and the makeup artist's workload will be relatively small. However, it should be noted that small crews may have problems such as insufficient funds and short shooting cycles, which may affect the quality of makeup artists' work.
In general, although the position of makeup artists in the crew is very important, whether the job is stable or not depends on the specific situation. If you wish to pursue a stable job in this industry, it is recommended that you do your due diligence and understanding when choosing a crew to ensure that you can adapt to the working environment and earn a stable income.
While the job of a makeup artist can be challenging in some cases, the industry is still very promising. With the continuous development of entertainment forms such as movies, TV series, and online dramas, the demand for makeup artists is also increasing. If you aspire to become a good makeup artist and constantly improve your skills and experience, I believe you will be able to get stable jobs and development opportunities in the industry.
