A skin care machine is operated by beauticians in clinics to improve the condition of the skin of the face and body. A unit transmits energy to a small wand, which is applied to the skin. Skin care machines emit different forms of energy, such as singular wavelengths of light, ultrasound and electric current. Some consumers choose to purchase commercial skin care devices for personal use, but manufacturers generally advise them to obtain the proper license before using these machines.
Advertisements of skin care machines claim that they immediately improve blood circulation and lymphatic drainage, as they increase the production of collagen and elastin. In addition, studies show that some machines get rid of the harmful bacteria that cause acne. Other visible benefits of the skin include reducing swelling of the eyes, lightening dark areas of the skin, toning and firming sagging skin and minimizing wrinkles and fine lines. In addition, manufacturers claim that they can reduce the appearance of cellulite.
A skin care machine that has a high frequency comes with a power generating unit and a rod. The interchangeable glass electrodes containing neon or argon gas fit under the tip of the rod. When it is turned on, electricity passes through the gas, causing the electrode to emit infrared light. The skin is heated with light, whether or not it is applied with a conductive gel. The power supply has adjustable dials that allow technicians to regulate the intensity of the electric current and the heat produced.
Blue Light skin care machines have a base power unit and rod with light emitting diodes or LEDs that generate blue light. The bacteria that cause acne absorb light, causing damage by free radicals, as well as the eradication of the organism. The red LED rods are designed to rejuvenate the skin, while the cells absorb light energy. It is believed that these dilate blood vessels and increase the supply of hemoglobin that carries oxygen. While dermatologists often use Yag erbtrium (yttrium and aluminum garnet), lasers for skin rejuvenation, beauticians use infrared light emitting lasers.
There is a milder type of skin care machine that causes biochemical and intracellular reactions to promote skin cleansing and tightening. As acupuncture points are stimulated, infrared light increases the rate of cell growth, increasing lymphatic activity and improving protein synthesis. Normally, wavelengths of 635 to 675 nanometers have an effect on the superficial cells of the skin. Machines that produce wavelengths that reach 1000 nanometers penetrate the deepest cells of the skin.
Most skin care centers use microdermabrasion machines. These exfoliate the top layer of the skin. They usually come with a wand that has an opening to apply a slight suction as it passes over the skin. During suction, the wand releases fine sand or crystals that scrape the surface layer of the skin. This procedure removes a thin layer of skin consisting of oils, dead cells, keratin and debris.
