A nail polish curing device with a light absorbing chamber is provided, including: a lower case, an upper case, a control module and a bottom plate. The lower case includes an enclosed wall and an opening on a side of the wall. A chamber is formed by the opening and the wall. The upper case is detachably mounted on the lower case. An upper opening and a recess that serves as a hidden handle are provided on the upper case. The control module is disposed on the upper case and is configured to activate UV light emitting diode module. Herein, a light absorbing layer is provided on the bottom plate and on each surface of the lower case in the chamber. The light absorbing layers are configured to completely absorb UV light emitted by the UV light emitting diode.

To provide a hair drier capable of emitting red LED light to the scalp efficiently to improve the scalp environment, a hair drier of the present invention is arranged such that a cover body provided at an air outlet of a blower has a facing surface that faces the head of the user in a state where the cover body is covering at least a portion of the head of the user, the facing surface being provided with an LED light-emitting section configured to emit LED light to the scalp of the head.

To provide a hair drier capable of improving the scalp environment, a cover body has an opening section and covers at least a portion of the head of the user in such a manner that the opening section faces the head, and a facing surface facing the head is provided with a plurality of LED light-emitting sections configured to emit LED light to the scalp of the head and is made of a highly reflective member.

The present disclosure relates to a gel nail curing device comprising a housing having internal space to accommodate the hand or foot where gel nail is applied, lighting part comprising a plurality of LEDs for curing said gel nail by emitting visible light toward the hand or feet; and controlling part controlling said LEDs of said lighting part, wherein said lighting part emits visible light reacting with a photoinitiator contained in said gel nail to promote curing of said gel nail.

A method of hair dying is provides that includes applying a polymer based hair dye to hair and emitting light on the applied polymer based hair dye for a duration to cure the polymer based hair dye on the hair. In certain aspects a device is provided that emits polymer curative energy for curing an applied polymer based hair dye that includes a housing, at least polymer curative light source disposed in the housing, and a controller operatively connected to the heat source and the at least one polymer curative light source. In certain embodiments a heat source is disposed in the housing that includes a polymer curative light source.

A battery powered blow dryer having a novel battery cooling feature to simultaneously cool the batteries and improve hair dryer performance.

An applicator for beauty products comprises a lighting device for providing lighting when applying beauty products. In various embodiments, the lighting device is a hollow body enclosing a power supply, such as one or more batteries, with the power supply and including a light source. The light source is surrounded by an opaque body so the light source casts an even glow of light. Further, the light source has in such a shape or an orientation allowing the light source to emit beyond an outer perimeter of one or more interchangeable brush heads that are coupled to an outer circumference of the light source. The hollow body also includes a switch coupled to the power supply and to the light source. When activated, the switch completes a circuit providing power from the power supply to the light source, causing the light source to emit light.

A system for improving a hair condition is provided in various embodiments. The system can have a sensor device having at least one sensor for detecting a hair condition parameter and a treatment device. The treatment device can have an illumination device for illuminating a scalp of a user with light and

an electronic circuit device coupled to the sensor device for receiving the detected hair condition parameter and/or a treatment parameter determined from the hair condition parameter by employing the sensor device, wherein the electronic circuit device can be configured to control an illumination of the scalp of the user using light by employing the illumination device based on the received detected hair condition parameter and/or the treatment parameter.

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.
