The present invention relates to a cosmetic ink application device which functions by producing a region as an alignment marker on human skin and detecting the region to align an applicator with the skin, and a method thereof. A cosmetic ink application device according to the present invention comprises: a light source for irradiating human skin with ultraviolet light; an optical sensor for detecting intensities of fluorescence in a ultraviolet range and/or a visible light range emitted from the skin in response to the irradiation of the ultraviolet light; an applicator for applying a cosmetic ink to the skin; a head portion for holding the light source, the optical sensor, and the applicator; and a controller, wherein the controller defines a region on the skin, which emits fluorescence having an intensity different from fluorescence emitted from other regions of the skin when irradiated with the ultraviolet light, as a marker region, wherein the controller determines a position of the ink application based on the marker region, and wherein the controller causes the applicator to apply the ink on a predetermined portion of the skin.

The present invention relates to a method for identifying ingredients or compositions, based on green chemistry performance, comprising the steps of: (a) identifying a cosmetic ingredient or a cosmetic composition; (b) calculating each of; (b1) a Green Chemistry Performance Score; (b2) a Binary Score; and (b3) a Certainty Score; and (c) selecting the cosmetic ingredient or the cosmetic composition having an aggregate score above the category average.

An object of the present invention is to provide a display nail tip suitable for being arranged, as samples of nail tips for nail art to be provided to customers, in a hard case, frames, boards, pedestals or the like and being presented to the customers or displayed in shops. Another object of the present invention is to provide a nail tip for the display nail tip described above and a nail tip positioning assistance tool. A display nail tip of the present invention includes a nail body (1) and a nail tip positioning assistance tool (14a, 14b) for assisting arrangement of the nail body on a nail tip display tool. The nail tip positioning assistance tool is integral-molded with any one of a thickness portion (3) of the nail body, a thick peripheral edge (1h) of the nail body, a concavely curved surface (1b) of the nail body, a base portion (4) arranged on the concavely curved surface (1b) of the nail body and a convexly curved surface (1a) of the nail body.

A device for producing a skin care pack using hydrogel and a control method of the device are disclosed. The device includes a housing which is provided with a door for selectively opening and closing a work space for forming a skin care pack, and which maintains a forming temperature required for producing the skin care pack; a platform having a base supported on a floor plate of the work space of the housing; a former including one or more nozzle modules which are provided to be movable in the work space, and each of which includes a pump for receiving a heated hydrogel and then discharging it onto the platform through a nozzle, and includes a cooling device for cooling a pump motor of the pump; and a control unit for controlling the discharge of the hydrogel from the nozzle modules.

The inventions relate to cosmetology and are intended to increase a cosmetic effect. A mask comprises a cream-type cosmetic agent and an additional reagent, which are isolated from one another. The agent contains a water-soluble biocompatible polymer which has a mass in the range of 50,000-1,000,000 Da and is capable of entering into a cross-polymerisation reaction. The reagent consists of a substance-electrolyte solution containing multicharged ions. The mass ratio of polymer and substance-electrolyte is from 10:1 to 1:1 respectively. A method involves separately applying to the skin the cream-type agent and then the additional reagent on top.

A beauty product device is disclosed which includes a variety of sensors for sensing the way in which a user is operating the device. The sensor data can be processed and compared with pre-stored data representative of a desired style and feedback messages generated and provided back to the user to help them achieve the style they wish to achieve based on the comparison.

Systems and methods for formulating a personalized skincare product for a user. Data inputs reflecting dermal information of the user (e.g., hydration level measurements, oil level measurements, and a photograph of the user's skin reflecting a set of skin concerns) are collected by a computing device and used to determine a set of normalized scores. A skin health data set is generated based on the normalized scores and stored in memory. A skin health metric is determined based on the skin health data set and is stored in memory. The computing device determines, using a machine learning framework, one or more first skincare product formulations based on the user skin health data set. The formulation(s) can be used to manufacture one or more customized skincare products for the user and can be iteratively refined over time, e.g., by collecting additional data from the user over time.

Systems, devices, and methods for generating, sharing, and presenting augmented reality cosmetic design filters. One or more non-transitory computer memory devices can store computer-readable instructions that, when executed by computing circuitry, cause the computing circuitry to perform operations for generating augmented reality cosmetic design filters. The operations can include defining a baseline description of a biological surface using one or more radiation sensors, the radiation sensors being electronically coupled with the computing circuitry. The operations can include identifying an application of a cosmetic formulation to the biological surface using one or more of the radiation sensors. The operations can include generating a trace describing the application in reference to the baseline description. The operations can also include outputting the trace.
