Light Therapy
Application of light rays to the skin for the treatment of disorders

2. Effects of various kinds of Light Therapy
Ultraviolet
Beneficial effects
Increases the elimination of waste products
Improves the flow of blood & lymph
Has a germicidal & antibacterial effect
Produces vita min D in the skin
Can be used to treat rickets (soft & deformed bones ), psoriasis & acne
Produces a tan

3. Effects of various kinds of Light Therapy
Infrared
Beneficial effects
Heats & relaxes the skin
Dilates blood vessels & increases circulation
Produces chemical changes
Increases metabolism
Increases production of perspiration & oil
Deep penetration relieves pain in sore muscles
Soothes nerves

4. Effects of various kinds of Light Therapy
White light
Beneficial effects
Relieves pain in the back of the neck & shoulders
Produces some chemical & germicidal effects
Relaxes muscles

5. Effects of various kinds of Light Therapy
Blue light
Beneficial effects
Soothes nerves
Improves skin tone
Provides some chemical & germicidal effects
Used for mild cases of skin eruptions
Produces little heat

6. Effects of various kinds of Light Therapy
Red light
Beneficial effects
Improves dry, scaly wrinkled skin
Relaxes muscles
Penetrates the deepest
Produces the most heat

7. 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

8. 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

9. 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

10. CAUTION:
DO NOT use faradic or sinusoidal currents if it causes pain or discomfort, if the face is very ruddy (red in color), or if your client has gold-filled teeth, high blood pressure, broken capillaries, or pustular skin conditions
Never use faradic or sinusoidal currents longer than 15 – 20 minutes

11. CAUTION:
Tesla high-frequency current should not be used on clients who are pregnant, suffer from epilepsy (seizures) or asthma or who have high blood pressure, a sinus blockage, a pacemaker, or metal implants

12. Visible light Electromagnetic radiation that we can see
Also called “radiant energy”
Visible light makes up 35%
of natural light
Ultraviolet rays & infrared rays are
forms of electromagnetic radiation

13. 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 light
referred to as “combination light”
benefits of all the rays of the visible spectrum
Blue light
should only be used on oily skin that is bare
contain few heat rays, is the least penetrating
some germicidal & chemical benefits
Red light
used on dry skin in combination with oils & creams
penetrates the deepest & produces the most heat

14. 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

15. 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

16. 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

17. 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

18. Infrared rays Make up 60% natural light sunlight Long wavelengths
Penetrate the deepest
Produce the most heat

19. 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

20. 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
