Abstract

Disclosed is a skin care device which performs skin care under the condition that it is attached to a user's face, performs both skin care using light and skin care using microcurrent, and prevents electrical interference between light source elements and microcurrent elements. The skin care device includes a non-conductive flexible substrate, at least one light source element provided on the flexible substrate, microcurrent elements provided on the flexible substrate, an insulating layer provided with first holes to expose the at least one light source element and second holes to expose the microcurrent elements, and a conductive layer including a plurality of conductive parts, each conductive parts contacting each microcurrent element through each second hole, and the conductive parts are divided so as to be spaced apart from one another and are provided with third holes to expose the at least one light source element.

Claims (21)

1. A skin care device comprising:

a non-conductive flexible substrate;

at least one light source element provided on one surface of the flexible substrate;

microcurrent elements including at least one positive electrode and at least one negative electrode and provided on one surface of the flexible substrate;

an insulating layer stacked on the flexible substrate and provided with first holes to expose the at least one light source element and second holes to expose the microcurrent elements; and

a conductive layer stacked on the insulating layer and including a plurality of conductive parts, a single conductive part contacting a single microcurrent element through each second hole,

wherein the conductive parts of the conductive layer are divided so as to be spaced apart from one another and are provided with third holes to expose the at least one light source element.

2. The skin care device according to claim 1 , further comprising a controller combined with the flexible substrate to selectively or simultaneously apply voltage to the at least one light source element and the microcurrent elements.

3. The skin care device according to claim 1 , wherein:

the insulating layer forms a side boundary of the skin care device; and

the side boundary of the insulating layer has a ‘V’ shape.

4. The skin care device according to claim 3 , wherein the conductive parts of the conductive layer include:

a first conductive part and a second conductive part corresponding to both ends of the ‘V’ shape; and

a third conductive part provided between the first conductive part and the second conductive part,

wherein the first conductive part, the second conductive part and the third conductive layer are spaced apart from one another.

5. The skin care device according to claim 1 , further comprising a gel pad stacked on the conductive layer.

6. The skin care device according to claim 1 , further comprising slits provided in at least one of the flexible substrate, the conductive layer and the insulating layer.

7. The skin care device according to claim 1 , wherein each of the conductive layer and the insulating layer includes a flexible material and has an inner surface with a concave shape.

8. The skin care device according to claim 1 , wherein the at least one light source element includes a plurality of light sources, and the light sources emit light having different wavelengths.

9. The skin care device according to claim 1 , wherein the insulating layer includes a receiving part forming a staircase in a region of the insulating layer corresponding to the conductive layer.

10. The skin care device according to claim 1 , wherein the conductive layer includes carbon silicone.
