Abstract

Claims (29)

1. A system for applying a formula, the system comprising: an applicator comprising: a reservoir configured to hold a formula, a roller ball configured to apply the formula, and an accelerometer configured to map a surface as the roller ball rolls and applies the formula; an attachment configured to couple the applicator to a dispensing device; and a dispensing device comprising: a light source configured to apply light treatment, wherein the dispensing device is configured to accept the applicator; the accelerometer comprises a 9-axis accelerometer.

2. The system of claim 1 , wherein the system further comprises a communication device.

3. The system of claim 2 , wherein the communication device comprises circuitry configured to:

visualize the surface;

highlight one or more areas of the surface, wherein the one or more areas of the surface are locations where the user has not yet applied the formula and/or locations based on a user history;

direct the user to roll the applicator over the one or more areas; and

store the user history, wherein the user history is each time the user applies the formula with the applicator.

4. The system of claim 2 , wherein the communication device is a smartphone.

5. The system of claim 1 , wherein the surface is a user's face.

6. The system of claim 1 , wherein the formula is applied simultaneously with the light treatment.

7. The system of claim 1 , wherein the light treatment comprises administering two or more wavelengths of light simultaneously.

8. The system of claim 1 , wherein the light source comprises a plurality of LEDs.

9. The system of claim 8 , wherein the plurality of LEDs is disposed in a ring around an end of the dispensing device.

10. The system of claim 9 , wherein the light source is further configured to indicate a direction a user should move the applicator by lighting up one or more of the plurality of LEDs in the direction around the ring.

11. A method of using the skin care system of claim 1 , the method comprising:

rolling a roller ball of an applicator across a surface;

applying formula from a reservoir in the applicator as the roller ball rolls;

administering light treatment from a light source on a dispensing device as the roller ball rolls; and

mapping the surface with an accelerometer in the applicator.

12. The method of claim 11 , wherein the method further comprises visualizing the surface with an application on a communication device.

13. The method of claim 11 , wherein the surface is a user's face.

14. The method of claim 11 , wherein the method further comprises directing the user to roll the applicator in a direction through the light source on the dispensing device.

15. The method of claim 11 , wherein the method further comprises:

visualizing the surface with the communication device; and

highlighting one or more areas of the surface.

16. The method of claim 15 , wherein the one or more areas of the surface are locations where the user has not yet applied the formula.

17. The method of claim 15 , wherein the method further comprises directing a user to roll the applicator over the one or more areas of the surface with the application on the communication device.

18. The method of claim 15 , wherein the method further comprises storing a user history based on the user using the device and the one or more areas the user rolled the applicator over.

19. The method of claim 15 , wherein the method further comprises directing the user to roll the applicator over the one or more areas based on the user history.
