A computer-implemented method of training a user to effectively apply makeup using a makeup brush, the method comprising:

• a. receiving, from a makeup brush movement tracking system that comprises at least one sensor for sensing the movement of the makeup brush relative to a particular portion of a user's body, data representing a movement of the makeup brush relative to the particular portion of the user's body over a particular period of time as the makeup brush is used to apply makeup brush to the particular portion of the user's body;
• and
• b. using the data to generate and display, to a user, a visual representation of the movement of the makeup brush over the particular period of time, wherein:
• the at least one sensor for sensing the movement of the makeup brush relative to the particular portion of the user's body is physically attached to an interior or exterior portion of the makeup brush.

A non-transitory computer-readable medium storing computer-executable instructions for training a user to effectively apply makeup using a makeup brush, the computer-executable instructions comprising instructions for:

• a. receiving, from a makeup brush movement tracking system that comprises at least one sensor for sensing the movement of the makeup brush relative to a particular portion of a user's body, data representing a movement of the makeup brush relative to the particular portion of the user's body over a particular period of time as the makeup brush is used to apply makeup to the particular portion of the user's body;
• and
• b. using the data to generate and display, to a user, a visual representation of the movement of the makeup brush over the particular period of time, wherein:
• the at least one sensor for sensing the movement of the makeup brush relative to the particular portion of the user's body is physically attached to an interior or exterior portion of the makeup brush.
