Radersi vs. rasarsi vs. farsi la barba
The Italian verbs radersi, rasarsi, and the expression farsi la barba all translate to the English concept of shaving oneself, but they carry distinct nuances and are used in different contexts. Understanding these subtle differences will help you choose the correct exact expression whether you are talking about shaving your face, shaving your head completely bald, or shaving your body.
Radersi
The verb radersi is the most standard, neutral, and versatile way to express shaving oneself. It refers universally to the act of removing hair from the skin using a razor and can be applied to any part of the body, such as the face, the legs, or the underarms.

Summary

Finally, farsi la barba is the most natural and frequently used expression for everyday conversation, but it is strictly restricted to a man shaving his facial hair.
