Abstract

PROBLEM TO BE SOLVED: To easily color the skin to increase laser beam-absorbing efficiency without applying cream. SOLUTION: The purpose of this invention is accomplished by applying translucent pack 1 to a treating skin surface and then by illuminating the skin surface with a laser beam from a laser radiation unit 2. The pack 1 comprises a coating material such as poly(vinyl alcohol) polymer, a poly(vinyl acetate) emulsion, or the like, a basis such as a denatured alcohol or purified water, a moisturizing agent such as 1,3-butylene glycol and an antiseptic agent such as p-hydroxybenzoate, and is mixed with carbon as a colorant. The carbon is added as carbon fine grains by being dispersed so that or the pack becomes optically translucent, and absorbs part of a semiconductor laser beam having 830 nm wavelength and transmits the rest on the basis of the property of light which is absorbed by a black substance and is reflected by white one. When carbon fine grains absorb the laser beam, Joulean heat generates to increase the temperature of skin surface part covered with the pack 1 and to promote the photothermal reaction by the laser beam.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pack for increasing the energy density of laser light by applying it to skin when irradiating laser light to perform treatments such as beautiful skin, slimming, hair loss and hair growth.

[0002]

Lasers that irradiate the human body are generally classified into two types: strong lasers utilizing thermal destruction and weak lasers utilizing photoactivation. The former is called a high response level laser, and is applied to the treatment of aza and the removal of cancer. The latter is called a low response level laser,
It is applied to promote blood circulation and metabolism by light activation, cure wounds early, inflammation and relieve pain.

[0003] Low-response level lasers are applied in the field of esthetics and cosmetics, are small and light, have good oscillation efficiency, operate at low voltage, operate at low voltage, have low unit prices, and have no risk of causing skin damage. Semiconductor lasers having characteristics such as life are often used.

However, the output of a semiconductor laser is 100 to
It is about 200 mW, which is extremely smaller than that for medical use.
Therefore, when performing a treatment using a photothermal reaction such as hair removal using a semiconductor laser, it was necessary to increase the energy density of the laser light by applying cream and coloring the pores black with carbon. For this reason, there is a problem that the cream is applied before the treatment and the cream is wiped off after the treatment, which is troublesome and troublesome. Also, if the cream penetrates the skin, it has to be washed to remove it, which is troublesome.

Accordingly, the present invention has been made to improve the efficiency of laser light absorption by easily coloring the skin without using a cream.

[0006]

In order to achieve the above object, the present invention is configured as follows.

That is, a translucent coating composition applied to the surface of the skin irradiated with laser light when performing treatment such as beautiful skin, slimming, hair loss, and hair growth by irradiating laser light, and a colorant that absorbs laser light. , A part of the laser beam is absorbed to generate heat, and the remaining portion is transmitted to increase the energy density of the laser beam.

[0008]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a schematic diagram of a laser treatment embodying the present invention. In the laser treatment, a translucent pack 1 is applied to the skin surface on which the treatment is to be performed, and the laser light of the laser device 2 is irradiated.

The pack 1 comprises a coating agent such as a high molecular weight compound such as polyvinyl alcohol and polyvinyl acetate emulsion;
A base such as denatured alcohol and purified water, a humectant such as 1,3-butylene glycol, and a preservative such as p-hydroxybenzoate are added, and carbon is added as a coloring agent.

Carbon is added so that carbon fine particles are dispersed and optically translucent. Then, by utilizing the property of light that is absorbed by a black substance and reflected by a white substance, a part of the semiconductor laser light having a wavelength of 830 nm is absorbed and the rest is transmitted. When the carbon fine particles absorb the laser light, Joule heat is generated to increase the temperature of the skin surface layer covered by the pack 1 and promote the photothermal reaction of the laser light.

The pack 1 may contain an anesthetic for surface anesthesia for hair removal or a steroid containing an antibiotic for aftercare. Various nutrients that are effective for beautiful skin and hair growth may be added.

The laser device 2 has a Ga. Al. An As semiconductor laser is used. Ga. Al. As semiconductor laser,
Gallium (Ga), aluminum (Al), arsenic (A
s) A semiconductor laser which combines the three materials, has excellent oscillation efficiency, has characteristics of oscillating at a low voltage of about 2 volts, and is smaller and lighter than a conventional laser device.

Ga. Al. The wavelength of the As semiconductor laser is 830 nm in the infrared region. The As semiconductor laser has an effect of increasing skin blood circulation by a thermal effect, and has excellent skin penetration because it is hardly absorbed by moisture or blood. The output is about 100 to 200 mW, and recently there is a high output of 400 mW, but there is no action of damaging the tissue and there is no danger of causing skin damage.

The laser treatment embodying the present invention is structured as described above, and irradiates the skin surface coated with the pack 1 with laser light from the laser device 2 to perform treatments such as beautiful skin, slimming, hair loss, and hair growth.

The beautiful skin irradiates a melanin such as aza, spot, bacterium and the like scattered on the epidermis and dermis of the skin with a laser beam through the pack 1, and generates heat when carbon fine particles absorb the laser beam and heat generated by the laser beam. The photoactivation action activates blood circulation and metabolism in the surface layer of the skin, removes wastes and foreign substances from the cell tissue itself, floats them on the surface, and attaches these wastes and dirt to the pack 1 and peels them off.

The epilation is performed by irradiating a sebaceous gland, which is located at the root of the pores and in the middle of the pores and in the middle of the pores and supplying keratin, which is a kind of protein and a factor of hair, with a laser beam, the heat generation effect of the pack 1 and the photothermal energy of the laser beam. The reaction promotes the denaturation and degradation of keratin and suppresses hair growth.

Hair growth is performed by irradiating a laser beam onto the pores, opening the pores by the heat generation effect of the pack 1 and the photothermal reaction of the laser beam, washing sebum and dirt clogged in the pores, removing waste products, and removing scalp. And introduce the hair growth nutrients contained in Pack 1.

In slimming, the acupuncture points which are closely related to the sympathetic nerve are irradiated with laser light, and the acupoints are stimulated by the heat generation effect of the pack 1 and the photothermal reaction of the laser light to refresh the body and relax the whole body. Let it.

[0020]

As described above, in the laser treatment pack of the present invention, a coloring agent that absorbs laser light is added, a part of the laser light is absorbed to generate heat, and the remaining part is transmitted to generate a laser light. Increase energy density. Therefore, according to the present invention, it is possible to easily color the skin and increase the energy density of laser light without using a cream,
This eliminates the hassle of applying or wiping cream as in the past, and provides a comfortable treatment. In addition, when the cream penetrates the skin, there is no need to wash the cream, and discomfort due to dirt is eliminated. Furthermore, since the wastes and dirt emerging on the skin surface when removing the pack can be removed together, it is hygienic. In addition, the treatment effect can be further increased by blending various nutrients.
