A system is provided that includes a mobile user device (300) that executes an application and determines and transmits a recipe for generating a target cosmetic material that is based on a combination of a plurality of separate ingredients that are associated with the user. The system includes a dispensing device (100) configured to receive the transmitted recipe from the mobile user device 300) and dispense each of the plurality of separate ingredients onto a common dispensing surface such that when the dispensed amounts of each of the plurality of separate ingredients is blended on the dispensing surface, the target cosmetic material is achieved.

A diffuser may include a diffusing case having a rear side removably coupled to a main body of a hair dryer. Fluid (such as gas or air) discharged from the main body is introduced into the diffusing case through an inlet hole defined at the rear side. The fluid introduced into the diffusing case is discharged to an outside through a front side of the diffusing case. A light irradiator may be provided inside the diffusing case to irradiate light toward the front side of the diffusing case. The light irradiator may include a plurality of light emitters arranged on a circuit board to emit light. Some of the plurality of light emitters may be spaced apart from others of the plurality of light emitters in a front-rear direction.

A skin care device can include a body including a battery and a grip electrode electrically connected to the battery, and a head connected to one end of the body. The head includes a contact electrode electrically connected to the battery and configured to come in contact with a skin of a user, and at least one ultraviolet light source disposed inside the head to face the contact electrode. Further, the contact electrode includes a fastening part fastened to the head and having at least one hole formed therein to correspond to the at least one ultraviolet light source, and a plurality of contact protrusions protruding from a top surface of the fastening part.

Provided is a continuous curing rate change type gel nail, and more particularly, a continuous curing rate change type gel nail characterized in that a curing rate of a resin portion of a gel nail is continuously changed from a soft property to a hard property.

A cosmetic activator system for activating a cosmetic is provided including: an activator having an energy source configured to emit an energy pulse and a controller; and an imprinter having an imprint pattern and at least one activation element configured to be in communication with the energy source, wherein the imprinter is configured to create an imprint on the cosmetic.

The present disclosure discloses a method of manufacturing a semi-cured gel nail for nail art, and more particularly, to a method of manufacturing a UV-C semi-cured nail cured by being irradiated with ultraviolet of a UV-C wavelength. A gel nail according to an embodiment of the present disclosure may have a smooth surface on which luster is maintained and no fingerprint marks or traces remain even when the gel nail comes in contact with a hand or a device.

A nail curing bowl comprising a hollow body. The hollow body includes a light-housing component removably attached to a base to create a UV irradiation area. The light-housing component includes a plurality of UV LED lights that generate UV radiation within the UV irradiation area. The hollow body further includes a hand rest that protrudes through an open top portion of the hollow body, allowing a user to rest the palm of their hand on the hand rest while extending their fingers downwards along the shaft of the hand rest into the UV irradiation area of the hollow body. The irradiation area is suitable for curing UV/LED curing product, while minimizing the user's exposure to the UV radiation emitted from the UV LED lights.

A UV LED curing apparatus can have an inner casing having a plurality of planes formed at a reflective angle with an outer casing detachably attached to the inner casing. The outer casing and the inner casing can define a space suitable for receiving an ultraviolet (UV) light emitting diode (LED) light source therein which can include a plurality of LED modules and at least one LED module arranged on two or more planes. An adjustable arm can be pivotally coupled with the outer casing at a proximal end and extend a predetermined distance to a distal end having a second UV LED light source including a second plurality of LED modules coupled therewith. A switch controller electrically connected to the UV LED light source and/or the second UV LED light source controlling an on-off state of the UV LED light source and/or the second UV LED light source.

A method of preparing a light-curable artificial nail includes extracting from an adhesive film in a semi-cured state a portion of the adhesive film in a shape of a human nail. The portion of the adhesive film includes a light-curable composition in the semi-cured state. A portion of the polish film in the shape of the human nail is extracted from a polish film. The portion of the adhesive film and the portion of the polish film are combined to form layers of the light-curable artificial nail.

A nail tip curing composition includes an Extend Gel, an edge-off flat brush, a nail filing device, a plurality of GEL-X tips, a pH Bonder, and a Non-Acidic Gel Primer. The pH Bonder forms a pH Bonder layer on a surface of a fingernail. The Non-Acidic Gel Primer forms a Non-Acidic Gel Prime layer overlapped on the pH Bonder layer. The Extend Gel forms an Extend Gel layer overlapped on the Non-Acidic Gel Prime layer. The GEL-X tip is filed by the nail filing device and the Extend Gel is applied on an underside contact surface of the Gel-X tip by the edge-off flat brush. The underside contact surface of the Gel-X tip is contacted with the Extend Gel layer on the fingernail in such a manner that the Gel-X tip is firmly affixed on the fingernail.
