Abstract

Claims (20)

1 . A method for selectively applying a composition to skin within an undereye region of a user, comprising:

obtaining, by a detector arrangement, image data corresponding to an image of an area of skin in the undereye region, the area of skin consisting of a plurality of skin frames imaged by the detector arrangement;

analyzing, by a processing arrangement, the image data to generate a target reflectance value higher than reflectance of at least half of the plurality of skin frames imaged by the detector arrangement;

determining, by the processing arrangement, a desired level of reflectance modification for a location within each of the plurality of skin frames by comparing image data corresponding to reflectance of the location to the target reflectance value; and

selectively applying, by an applicator arrangement, the composition to each location based on the corresponding desired level of reflectance modification determined for the each location.

2 . The method of claim 1 , wherein the target reflectance value is higher than reflectance of at least 70%, at least 75%, at least 80%, at least 90%, at least 95% or at least 99% of the plurality of skin frames imaged by the detector arrangement.

3 . The method of claim 1 , wherein the target reflectance value corresponds to an average reflectance across a target frame selected from the plurality of skin frames.

4 . The method of claim 3 , wherein the target frame is selected by

determining an average or median reflectance value for each of the plurality of skin frames,

comparing the average or median reflectance values for the plurality of skin frames, and

selecting as the target frame an area having a higher average reflectance value as compared to at least half of the plurality of skin frames.

5 . The method of claim 4 , wherein the target frame has a higher average reflectance value as compared to at least 70%, at least 75%, at least 80%, at least 90%, at least 95% or at least 99% of the plurality of skin frames.

6 . The method of claim 1 , wherein the area of skin in the undereye region has an elongated shape and the plurality of skin frames are arranged in a linear array along a length of the elongated area of skin.

7 . The method of claim 1 , wherein the applicator arrangement withholds from applying the composition when the applicator arrangement is positioned within about 3 mm to about 5 mm from a lower edge of an eye of the user.

8 . A handheld device for selectively applying a composition to skin within an undereye region of a user, comprising:

a detector arrangement obtaining image data corresponding to an image of an area of skin in the undereye region, the area of skin consists of a plurality of skin frames imaged by the detector arrangement;

an applicator arrangement comprising a plurality of nozzles applying the composition to the area of skin, wherein each of the plurality of nozzles is aligned to apply the composition to skin within a corresponding skin frame selected from the plurality of skin frames imaged by the detector arrangement; and

a processor and a non-transitory computer readable storage medium including a set of instructions executable by the processor, the set of instructions operable to analyze the image data obtained by the detector arrangement to select a target frame from the plurality of skin frames, and to generate a target reflectance value based on image data corresponding to reflectance across the target frame, analyze the image data obtained by the detector arrangement to generate a target reflectance value higher than reflectance of at least half of the plurality of skin frames imaged by the detector arrangement, determine a desired level of reflectance modification for a location within each of plurality of skin frames by comparing image data corresponding to reflectance of the location to the target reflectance value, and direct the applicator arrangement to selectively apply the composition to each location based on the corresponding desired level of reflectance modification determined for the each location.

9 . The device of claim 8 , wherein the applicator arrangement comprises a grated end effector defining the plurality of skin frames within the imaged area of skin.

10 . The device of claim 8 , wherein the grated end effector has an elongated shape and the plurality of skin frames defined by the grated end effector are arranged in a linear array along a length of the grated end effector.
