Red light Beneficial effects

Improves dry, scaly wrinkled skin Relaxes muscles Penetrates the deepest Produces the most heat

Light Therapy

Artificial light rays are produced by an electrical apparatus called a therapeutic lamp

In some states it is illegal to cause visible muscle contractions with faradic or sinusoidal currents. Always check w/your regulatory agency

CAUTION:

For high-frequency current, either direct or indirect, the same contraindications apply as for galvanic current

In addition, the client should avoid any contact w/metal, such as chair arms, stools, jewelry, & metal bobby pins during the treatment

A burn may occur if such contact is made

CAUTION:

Client’s eyes always should be protected during any light ray treatment

Use cotton pads saturated w/alcohol-free freshener or distilled water

The eye pads protect the eyes from the glare of the reflecting rays

Visible light

Violet has the shortest wavelength & red has the longest

Primary source of light used for facial and scalp treatments

Bulbs used for therapeutic visible light therapy are white, red, and blue

White lightreferred to as “combination light”benefits of all the rays of the visible spectrum

Blue lightshould only be used on oily skin that is barecontain few heat rays, is the least penetratingsome germicidal & chemical benefits

Red lightused on dry skin in combination with oils & creamspenetrates the deepest & produces the most heat Brought to you by

Therapeutic lamps

Used to produce artificial light rays in the salon

Capable of producing the same rays that are produced by the sun

Three effects produced by therapeutic lamps are: Thermal ( heat ) Mechanical Chemical Brought to you by

Ultraviolet rays (UV)

Make-up 5% of natural sunlight and are also referred to as cold rays or actinic rays

Least penetrating rays Produce chemical effects Kill germs

Brought to you by

Page 16: Light therapy

Ultraviolet rays (UV)

Exposure to the sun can be beneficial if guidelines are followed

Natural sunlight kills germs and produces vitamin D in the skin

Stimulates the skin’s production of melanin, which causes a tan and helps protect the skin from further damage But deep tanning is another matter

It is a sign that the skin is under attack from UV radiation Brought to you by

Page 17: Light therapy

Ultraviolet rays (UV)

Over 1 million new cases of skin cancer are diagnosed each year

Estimated that 1 in 5 will develop skin cancer & 90% of those cancers will be the result of exposure to UV radiation from the sun and from tanning beds

Brought to you by

Infrared rays

Make up 60% natural light sunlight Long wavelengths Penetrate the deepest Produce the most heat

Did You Know……..

Although salon lighting is not a form of light therapy, the quality of this light can have an effect on your work and your client’s satisfaction

Fluorescent light is produced by fluorescent lamps and is much cooler (green-blue) than natural sunlight

Incandescent light is produced by standard (tungsten) light bulbs and is warmer (yellow-gold) than either natural sunlight or fluorescent light

Brought to you by

Page 20: Light therapy

Did You Know……..

Your client’s hair and skin will appear more green-blue when viewed with fluorescent lighting and more golden when viewed with incandescent lighting

Take caution when handling fluorescent light bulbs; they contain dangerous substances, including mercury

Be careful not break fluorescent bulbs, and dispose of used bulbs properly Brought to you by
