Describe a situation where a cosmetologist might need to know basic information about one of the major systems (skeletal, muscular, endocrine, circulatory, etc.).

For example, a comprehensive understanding of the muscles localized in the face can help in the application of facial treatments (i.e., for skin rejuvenation, anti-aging, etc).

Explanation :

Cosmetologists are professionals that provide different types of personal care services (i.e., people's hair care/skincare routines, nails care and more). The cosmetologists can be barbers, hairstylists, skincare specialists, etc. In the work of a cosmetologist, it is important to take into account the main systems of the human body and its anatomy because this information will help them to understand how a person reacts to a given treatment.
