FREQUENTLY ASKED QUESTIONS
1. What is light?
We normally refer to the visible part of the spectrum as light. Visible light is only a small portion of the range of energy used in tanning.
2. How is light measured?
Light is measured by the length of the wave. This is an extremely small distance and is referred to as a nanometer (nM). There are 1 000 000 000 in every 39 inches.
3. What is Ultra Violet light?
There are different types of light associated with the tanning process. Ultra Violet, which is comprised of UVA and UVB rays, as well as visible and infrared light. UVB light stimulates the tanning process. It is the most powerful form of UV light and is responsible for sunburn. It is vital to have UVB to initiate the tanning process, but not enough to cause overexposure. UVA light is responsible for the dark, golden color results. Visible light is the light you see in a rainbow, we use the violet color to see the rays and assist in the tanning process. Finally, there is infrared light, which is associated with heat and can cause discomfort while tanning.
4. What is UVA?
UVA is the portion of UV with wavelengths between 320nM and 400nM. It is primarily responsible for the oxidizing in the tanning process.
5. What is UVB?
UVB is the portion of UV with wavelengths between 280nM and 320nM. It is primarily responsible for stimulation of the tanning process.
6. What is Infrared?
Infrared is the light beyond the visible spectrum above 700nM. It is primarily associated with heat although near infrared, which is (-700 - 1500nM), is similar to the soothing warmth of the sun delivered early morning and late evening.
7. What Mix of light is contained in natural sunlight?
Natural sunlight varies considerably according to the time of day, season and proximity to the equator. UVB levels in the early morning are low as these wavelengths bounce of the earth's atmosphere, gradually increasing to a peak that can be as high as 10% by mid-day.
8. What light is used in tanning beds?
A mixture of light from different portions of the spectrum is required to effectively tan the skin. It is only through this mixture of wavelengths right across the spectrum that we can control the optimum tanning performance.
9. What characterizes a low-pressure bed?
Tanning beds, which deliver power from fluorescent type tubes, are referred to as low-pressure beds. The output of low-pressure beds tends to be rich in UVB and low in UVA.
10. What characterizes a medium-pressure bed?
When high-pressure facial lamps are added to a low-pressure bed it is referred to as a medium-pressure bed.
11. What characterizes a high-pressure bed?
High-pressure sunbeds use only Quartz lamps to deliver results. These lamps have a much lower content of UVB, thus reducing the risks of burning and allowing your skin to maintain a normal exfoliation process. Therefore results by high pressure tanning last much longer!
12. What is the difference between high pressure and low pressure?
Low-pressure beds are characterized by having high levels of UVB whereas high-pressure beds have increased levels of UVA and lower levels of UVB. Higher levels of UVA allow the tan to last longer and reduce the risk of UVB burning.
13. How do I explain high pressure tanning to my clients?
A simple explanation would be that Natural sunlight varies during the day from low UVB in the early morning to high UVB in the mid day sun. Low pressure tanning has the sunburn potential of the midday sun and the sun tanning potential of the early morning sun. High pressure offers the tanning potential of the mid-day sun and the burning potential of the early morning sun.
14. What would be the perfect tanning light?
The perfect tanning light has enough UVB to stimulate production of melanin, the tanning power delivered by UVA, production of vitamin D, and the warmth of near Infrared. This combination can only be found in Spectrum tanning
