Incandescent Light
To balance the tones of light in the salon, a second source of light can be used.
This source is called incandescent light. This kind of light is provided by an
ordinary light bulb. Normally this light produces redder tones or warmer casts
in the objects it lights. Although more expensive to operate and replace than flu-
orescent light, incandescent light creates the closest substitute for natural sunlight.
Salon owners need to plan a balance of incandescent and fluorescent lighting in the salon design.
Proper lighting systems can have a pleasant psychological effect on staff and clients. Fluorescent
light can be irritating to some people, while incandescent light can create excessive heat. Lighting
should be comfortable to work under and easy to adjust.
Invisible Light
Cosmetologists use invisible light to produce physical effects in the skin. Since this range of light is
not visible to the human eye, you can be overexposed to invisible light in natural sunlight without
knowing it.
Eighty percent of sunlight is composed of invisible rays beyond red, which are called
Eight percent of natural sunlight is composed of invisible rays beyond violet, which are
called ultraviolet.
Small doses of infrared or ultraviolet light can produce beneficial effects. Using either ultraviolet or
infrared light to treat the skin is called light therapy.
Infrared Light
Just as infrared rays produce pure heat rays, any infrared light produces heat. Heat lamps
or infrared bulbs can be purchased for use in processing chemical services. Take care
to position the lamps according to the manufacturer's instructions.
Benefits of using infrared light during a facial include:
1. Increased circulation
2. Increased skin gland secretions
3. Relaxation of muscles
4. Stimulation of cell and tissue activity
Exposure times range from 5 to 15 minutes. The light must be placed at least 30 inches from the
client's face. Eye pads or protective eye forms must be used to cover the client's eyes.
Ultraviolet Light
Ultraviolet rays, also known as actinic rays, have a shorter wavelength and can be more
damaging than infrared rays. Ultraviolet light, or UV, produces both positive and negative
effects on the skin, depending on the exposure time. Small doses of UV light can tan the skin
and may help the body produce Vitamin D. UV light is germicidal and can kill bacteria that
