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

A method for enabling a subject to gauge effectiveness of at least one beauty product, the method comprising:

• receiving first data, wherein the first data is representative of at least one condition of an external body portion of a subject in a first time frame;
• receiving second data, wherein the second data is 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, and wherein at least one beauty product is applied to the external body portion between the first time frame and the second time frame;
• generating evolution data based at least in part on the first and the second data;
• presenting the subject a first representation of the evolution data;
• and
• presenting the subject, in conjunction with the first representation, a second representation of an expected evolution of the at least one condition, the conjunctive presentation of the first and second representations being configured to permit the subject to gauge effectiveness of the beauty product applied between the first and second time frames.

A system for enabling a subject to gauge effectiveness of a beauty product, the system comprising:

• a data receiving module for receiving first data and second data, wherein the first data is representative of at least one condition of an external body portion of a subject in a first time frame, the second data is 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, and at least one beauty product is to the external body portion between the first time frame and the second time frame;
• a processor for generating evolution data based on the first and second data, the evolution data representing evolution of the external condition between the first and second time frames;
• and
• a graphical generator for causing the subject to be presented conjunctively with a first representation of the evolution data and a second representation of an expected evolution of the at least one condition, the conjunctive presentation of the first and second representations being configured to permit the subject to gauge effectiveness of the beauty product applied between the first and second time frames.

A method for predicting evolution of at least one condition of an external body portion of a subject, the method comprising:

• receiving first data, wherein the first data is representative of the at least one condition;
• receiving second data, reflective of how the at least one external body condition is expected to evolve over time, wherein the second data is derived using characteristic data collected from the subject;
• generating, based on the first data and the second data, a forecasted evolution of the at least one condition;
• and
• transmitting to the subject the forecasted evolution.

• a data receiving module for receiving first data and second data, wherein the first data is representative of at least one condition of an external body portion of a subject and the second data is reflective of how the at least one external body condition is expected to evolve over rime with at least one application of a beauty product;
• a processor for generating evolution data based on the first and second data, the evolution data representing evolution of the external condition;
• and
• a graphical generator for causing the subject to be presented conjunctively with a first representation of the evolution data and a second representation of an expected evolution of the at least one condition, the conjunctive presentation of the first and second representations being configured to permit the subject to gauge effectiveness of the beauty product.
