The treatment device has a camera for taking an image of the skin. The system may include or be in communication with an application programming interface (API) that can process the image. The system or an associated API can recommend the use of treatment regimens or topical products according to information determined from the digital image of the skin. ## Claims ### Claim 1 A personal care device comprising: a handle portion; a head portion disposed at an end of the handle portion, the head portion including a platform; a treatment head extending away from the platform along a first direction of a longitudinal axis of the head portion; and a lens module positioned within the head portion, the lens module comprising a compartment that is enclosed by a cover and a housing of the head portion, the lens module comprising a camera lens and a light source that are each disposed within the compartment, wherein the camera lens faces away from the platform along a second direction of the longitudinal axis, the second direction opposite the first direction. ### Claim 2 (depends on 1) The personal care device of claim 1, wherein the treatment head is reversibly detachable from the platform. ### Claim 3 (depends on 1) The personal care device of claim 1, wherein the treatment head is selected from the group consisting of a facial brush, a micro current device, a LED light device, and an ultrasound device. ### Claim 4 (depends on 1) The personal care device of claim 1, wherein the light source is a LED light. ### Claim 5 (depends on 1) The personal care device of claim 1, further comprising a sensor disposed on the handle portion and adjacent to the cover. ### Claim 6 A personal care device comprising: a handle portion comprising a grip portion that extends along a first longitudinal axis; a head portion positioned at an end of the handle portion, the head portion including a platform; a treatment head coupled to the platform, the treatment head extending away from the platform in a first direction along a second longitudinal axis that is transverse to the first longitudinal axis; a controller disposed on the handle portion and oriented to face toward the first direction, the controller disposed on a medial plane of the handle portion such that the controller is centered relative to the treatment head when the device is viewed facing the controller; and a lens module positioned within the head portion, the lens module extending away from the platform along the second longitudinal in a direction opposite the first direction. ### Claim 7 (depends on 6) The personal care device of claim 6, wherein the treatment head is selected from the group consisting of a facial brush, a micro current device, a LED light device, and an ultrasound device. ### Claim 8 (depends on 6) The personal care device of claim 6, further comprising a light source, wherein the light source is a LED light. ### Claim 9 (depends on 6) The personal care device of claim 6, further comprising a sensor disposed on the head portion. ### Claim 10 A personal care device comprising: a handle portion; a head portion positioned at an end of the handle portion, the head portion including a platform; a treatment head extending from the platform, wherein the treatment head extends away from the platform along a first direction of a longitudinal axis of the platform when the treatment head is coupled to the platform; a lens module positioned within the head portion, the lens module comprising a camera lens facing away from the platform along a second direction of the longitudinal axis, the second direction opposite the first direction; a camera controller button disposed on the handle portion and facing toward the second direction; and an indicator disposed on the handle portion and between the camera controller button and the camera lens. ### Claim 11 (depends on 10) The personal camera device of claim 10, wherein the indicator is configured to allow a user to aim the camera lens based on feeling the orientation of the indicator relative to the camera controller button. ### Claim 12 (depends on 10) The personal camera device of claim 10, wherein the lens module comprises a compartment that is enclosed by a cover and a housing of the head portion, the camera lens disposed within the compartment. ### Claim 13 (depends on 10) The personal care device of claim 10, further comprising a sensor disposed on the handle portion. ### Claim 14 A personal care device comprising: a handle portion; a head portion at end of the handle portion, the head portion including a platform; a treatment head extending from platform, wherein the treatment head extends away from the platform along a first direction of a longitudinal axis of the platform when the treatment head is coupled to the platform; a lens module positioned within the head portion, the lens module facing away from the platform along a second direction of the longitudinal axis, the second direction opposite the first direction; and a sensor disposed on the head portion, the sensor adapted for measuring a characteristic of a skin. ### Claim 15 (depends on 14) The personal care device of claim 14, wherein the characteristic measured by the sensor is selected from the group consisting of: a moisture content, a pore size, a pore count, a sebum amount, a sebum composition, an elasticity, a fine line count, a fine line branching, a wrinkle count, and a wrinkle depth. ### Claim 16 (depends on 14) The personal care device of claim 14, wherein the device is in contact with the skin when the sensor measures the characteristic of the skin. ### Claim 17 (depends on 14) The personal care device of claim 14, wherein the device is spaced apart from the skin when the sensor measures the characteristic of the skin.
