Abstract

An apparatus for modifying a keratinous surface that has an applicator that with a motor, and at least one protrusion The applicator further has a ribbon with a first and second side, the first side being adjacent the protrusion and a first modification composition on the second side of the ribbon. Further there is a sensor and a CPU. The sensor reads the properties of a small portion of the keratinous surface, the readings are transmitted to the CPU. If the CPU sends a signal to the applicator to treat the surface, the motor is activated to move the applicator to the keratinous surface such that the ribbon contacts the keratinous surface near the protrusion to apply a portion of the first modification composition to the keratinous surface that was read by the sensor.

Claims

1. An apparatus for modifying a keratinous surface comprising:

an applicator that comprises a motor, at least one protrusion, a ribbon having a first and second side, the first side being adjacent the protrusion and a first modification composition on the second side of the ribbon;

a sensor;

a CPU;

wherein the sensor reads the properties of a small portion of the keratinous surface, the readings are transmitted to the CPU, the CPU analyzes the sensor reading of the keratinous surface, the CPU sends a signal to the applicator to treat or not to treat the analyzed surface, and wherein if the CPU sends a signal to the applicator to treat the surface, the motor is activated to move the applicator to the keratinous surface such that the ribbon contacts the keratinous surface near the protrusion to apply a portion of the first modification composition to the same portion of the keratinous surface that was read by the sensor.

2. The apparatus of claim 1, where the applicator comprises two or more protrusions.

3. The apparatus of claim 1, where the ribbon is moved each time the motor is activated to such that each time the ribbon contacts the keratinous surface the ribbon contains a portion of the first modification composition.

4. The apparatus of claim 2, wherein each protrusion has a different shape, a different surface area or both.

5. The apparatus according to claim 1, wherein the first modification composition is an adhesive, and after the apparatus treats the keratinous surface, a second modification composition is applied to the keratinous surface which sticks to the adhesive completing the modification of the keratinous surface.

6. The apparatus according to claim 1, wherein from about 1.0% to about 10% of the keratinous surface that is read by the sensor is modified by application of the first modification composition.

7. The apparatus according to claim 1, wherein the applicator applies from about 0.01 μ

g to about 100 μ

g of the first modification composition to the keratinous surface when the applicator is activated by the CPU.

8. The apparatus according to claim 1, further comprising a second modification composition.

9. The apparatus according to claim 1, wherein the readings made by the sensor contain a value for a characteristic selected from the group of color, brightness, reflectance, temperature, texture, and mixtures thereof.

10. The apparatus according to claim 1, wherein the first modification composition is selected from the group consisting of inks, dyes, pigments, adhesives, curable compositions, optically activated compounds, hair colorants, hair removal compositions, hair growth stimulants, metal oxides, bleaching agents, texture reducing polymers, skin care compositions, and mixtures thereof.

11. The apparatus according to claim 1, wherein the keratinous surface has an outer surface of from about 1 mm to about 5 mm in thickness and an inner core directly below the outer surface, and wherein the sensor reads the inner core or the keratinous surface.

12. The apparatus according to claim 1, wherein the applicator applies the first modification composition in droplets having an average diameter of from about from about 0.1 μ

m to about 50 μ

m.

13. An apparatus for modifying a keratinous surface comprising:

an applicator that comprises a motor, at least one protrusion, a ribbon having a first and second side, the first side being adjacent the protrusion and a first modification composition on the second side of the ribbon;

a sensor;

a CPU;

wherein the sensor reads the properties of a small portion of the keratinous surface, the readings are transmitted to the CPU, the CPU analyzes the sensor reading of the keratinous surface, the CPU sends a signal to the applicator to treat or not to treat the analyzed surface, and wherein if the CPU sends a signal to an operator of the device, the operator then chooses to treat or not to treat the identified portion of the keratinous surface, when the operator chooses to treat the portion of the keratinous surface she activates the motor to move the applicator to the keratinous surface such that the ribbon contacts the keratinous surface near the protrusion to apply a portion of the first modification composition to the same portion of the keratinous surface that was read by the sensor.

14. The apparatus according to claim 13, wherein the signal sent to the operator is selected from the group consisting of visual, auditory, tactile and mixtures thereof.

15. An apparatus for modifying a keratinous surface comprising:

an applicator that comprises a motor, at least one protrusion, a ribbon having a first and second side, the first side being adjacent the protrusion and a first modification composition on the second side of the ribbon;

a sensor;

wherein the sensor reads the properties of a small portion of the keratinous surface, the readings are analyzed, the sensor sends a signal to the applicator to treat or not to treat the analyzed surface, and wherein if the sensor sends a signal to the applicator to treat the surface, the motor is activated to move the applicator to the keratinous surface such that the ribbon contacts the keratinous surface near the protrusion to apply a portion of the first modification composition to the same portion of the keratinous surface that was read by the sensor.
