Methods and systems for predicting and/or tracking changes in external body conditions

摘要

The present invention includes a method for predicting evolution of at least one condition of an external body portion of a subject. The method may include receiving first data, receiving second data, generating a forecasted or expected evolution of the at least one condition of the external body portion of the subject based on the first data and the second data, and transmitting to the subject the forecasted evolution. The first data may be representative of at least one condition of the external body portion of the subject in a first time frame. The second data may be representative of the at least one condition of the external body portion of the subject in a second time frame occurring after the first time frame. A beauty product may be applied to the external body portion between the first and second time frames.
