Connected formula identifiable by device low cost sensor to customize treatment

A skin treatment sensor device comprising:

• one or more skin sensors configured to collect a plurality of skin surface measurements;
• a skin treatment effectiveness unit that is electrically coupled with the one or more sensors comprising:
• a processor configured to identify a type and an amount of at least one topical skin treatment formula applied to a skin surface based on the plurality of skin surface measurements;
• a memory unit electrically coupled with the processor, the memory unit configured to store a plurality of reference values corresponding to a type and amount of the topical skin treatment formula applied to the skin surface and a plurality of user baseline measurements corresponding to the skin surface;
• and
• a user alert unit electrically coupled with the processor, the user alert unit configured to present one or more notifications to a user.

A method for determining the effectiveness of a skin treatment, the method comprising:

• collecting a plurality of user baseline measurements;
• applying at least one topical skin treatment formulas to a skin surface;
• identifying, by a skin treatment sensor device, the at least one topical skin treatment formulas applied to the skin surface;
• collecting a plurality of skin surface measurements;
• comparing a plurality of reference values corresponding to a type and amount of the topical skin treatment formula applied to the skin surface, the plurality of skin surface measurements, and the plurality of user baseline measurements corresponding to the skin surface;
• and
• alerting a user of the effectiveness of the skin treatment.
