What is the difference between Cold Laser Light Therapy and LED Light Therapy?

Many companies who sell LED Light Therapy equipment will call their equipment Cold Laser Light Therapy.  Simply referring to LED Light Therapy as Cold Laser is actually quite misleading and technically not the correct terminology.  Let us explain why this is incorrect as simply as possible.

Lasers, by their very nature, deliver high heat energy which is directed or targeted at specific skin tissues or chromophores in the skin.  This high heat energy or thermal energy, commonly referred to as selective photothermolysis, is used to damage or injure specific skin tissues or chromophores.  The skin, in response to this injury or wound, will go through many processes to heal this injury or wound.  As a result of this healing process, the skin tissues are rejuvenated.   Lasers deliver this high heat energy in a very focused thin beam of light , which is referred to as collimated light.   This focused thin beam of light maintains a constant diameter regardless of its distance from the object, (ie.  skin).    LEDs do not deliver energy in a very focused thin beam of light(ie. collimated), like a Laser, but rather as a broad band light source.   Meaning, the actual LED diode does not emitt a very narrow focused beam of light like a Laser does. 

With LEDs, light emitting diodes, they do not deliver high heat energy to injure, destroy or burn specific skin tissues or chromophores, but rather the skin cells are stimulated by absorbing specific wavelength energies to begin the rejuvenation process.  Sometimes companies will refer to LEDs as "cold light therapy" because the LEDs do not use high heat energy to injure or wound skin tissues to achieve skin rejuvenation.  To compound the confusion even more, many individuals hear the word "cold" and expect the LED Light treatment to give a cooling or cold sensation on the skin.    

The confusion is compounded by  various licensed aesthetic professionals calling their photorejuvenation treatments "Cold Laser Light Therapy" treatments or facials, when in fact, they are using LED-light emitting diodes.  Referring to a LED Light Therapy treatment as "Cold Laser"  only perpetuates misinformation and confuses the client, consumer and professional.   LED Light Therapy is a non-prescription( meaning you do not need a prescription from a physician to have a LED treatment); non-Laser( meaning not  a medical Laser or IPL) , and non-medical treatment( meaning you do not need to be a Physician, Physician Asisstant, or RN to provide LED Light Therapy). 

If a non-medical professional, such as a licensed aesthetician or cosmetologist, were to operate a "true" medical Laser or IPL ( Intense Pulsed Light)  in her spa or salon, then this aesthetician or cosmetologist is practicing medicine without a medical license, which is against the law in all 50 states. Exceptions to this rule, some states allow non-medical professionals, meaning an aesthetician,  to operate a Laser only under direct supervision by a licensed medical professional( MD, Physician Assistant, RN).  And there are some states that allow non-medical professionals to operate Lasers for hair removal only.


Do all LED light skin therapy companies use the same "red" wavelengths?

Most people come to the conclusion, after spending hours on the internet researching LED light therapy skin rejuvenation, that every LED red light therapy and/or infrared LED light therapy device for anti-aging treatments are all made the same and there is absolutely no difference from one company to the next.

The biggest mistake a person makes is thinking that if one company advertises their light as having "red" light or "red" wavelengths, then all companies who sell LED light therapy equipment use the same "red" light or "red" wavelengths.  They figure "red" is "red" and they base their purchase on that. That same thinking is applied to blue, green, amber and so forth.

LED Light therapy is not just about using the color "red" or the color "blue" or the color "amber".   It is about using very specific "red"wavelengths, or specific "blue" wavelengths, or specific "infrared" wavelengths, referred to as nanometers, to improve various conditions on the skin/body. 

For example, you have a radio and you have numerous radio stations to choose from.  You have talk radio, sports, news, weather, music, and so forth.   If you wanted to specifically listen to  jazz music on your radio, you would have to tune into that exact radio station channel on your radio to hear  jazz music.  That jazz station can only be tuned in at 97.4FM(example only).   You would not turn your radio dial to the country music station, which is 103.5FM(example only), if you wanted to listen to jazz.

When choosing LED light equipment, one must never talk in terms of the name of the color, such as red, blue, green, etc. , but in nanometer.  Asking if a particular piece of equipment has "red" wavelengths, is vaque.   The nanometer is the exact number for that specific wavelength of "red".   There can be a 633nm( called 633 nanometer) or a 650nm, or a 620nm and so on.  There are numerous "red" wavelengths.  To the human eye, the red spectrum can appear as red, red-orange, deep red, light red, and many other colors in between.  For example, take the term "Infrared", which "infra"means -below or after and "red".  Infrared wavelength frequencies are not visible to the human eye.  When it comes to red light therapy, or blue LED light therapy, or infrared LED light therapy, etc., there are certain, specific wavelengths( nanometers) that have been proven, in clinical studies and research papers, to be more effective than other  wavelengths.

When choosing LED light therapy equipment, the correct wavelengths along with other technical specifications are extremely necessary for an effective LED light therapy treatment.

In conclusion, the best LED light therapy system will incorporate multiple, specific wavelengths that have been shown through clinical research to be effective for LED light therapy for skin rejuvenation.


Does "pulsing" or providing different power settings make a LED Light treatment more effective?

The concept of pulsing, such as with Intense Pulsed Light Lasers, comes from the thought that if one "pulsed" the intense light, it would reduce or minimize the thermal damage to the non-treated surrounding skin tissues. Pulsing is used to control this high heat energy. For example, when treating a blood vessel, one would want to specifically target the blood vessel while minimizing the damage to the skin tissues that surround that blood vessel. These periods of "pulsing" the high heat energy is followed by a very short period of "pulse delay".  This pulse delay is often referred to as the thermal relaxation period. During this "pulse delay", where no high heat energy is being applied, the tissues are allowed to cool preventing permanent thermal tissue damage.

With LEDs, we are not using high heat energy or high heat laser energy to destroy or injure skin tissues, therefore there would be no need to pulse the LEDs.  Keep in mind, that if one were to pulse or flash a LED, then there would be a period of "no light" which would decrease the light output. Having various settings with LEDs, such as a high setting or low setting would not be necessary because LEDs are either on or off.  Either the LED is operating correctly or it is not.  LED Phototherapy is based on cells absorbing light energy and not  whether there is high/low settings or pulsing light.  With LED light treatments, we want maximum light output through out the entire treatment.


Why is there such a huge price range in LED/Phototherapy devices on the market?

There are many units/devices out there in the market place that are absolutely made with very inexpensive components, incorrrect wavelengths, exaggerated power output, while providing misleading information and testimonials.   Its simple as that.  Unfortunately, since the advent of the internet, you simply do not know who to trust or believe any more. 

Then, there are the companies who charge thousands for their unit/device.  They say they are the best or the first. They say they developed the technology when in fact the technology has been out there a very long time. Companies that charge a lot, do so because they have either high overhead expenses such as marketing/advertising costs, sales people, buildings, or they have huge profit margins.


Why don't you charge more for your devices?

We have priced our LED Light Therapy Devices far below what other companies charge who provide substantially less quality, effectiveness, training, and personalized service.  We did this because we wanted our products to be affordable to just about anyone who wants to own our devices.   We put our money into the components and eliminated the things that really have very liitle to do with the over all results. We wanted to make this technology affordable, high quality and results-oriented. Since we are the manufacturer we can pass the savings on to you.  Furthermore, we are honest business people.


How do I know that your device has the correct specifications?

Since we are the manufacturer and engineered, designed, every aspect of our devices we know exactly what wavelengths, milliwatts, joules, viewing angle, volts, and currents, to name a few, have been incorporated into our device. When you purchase our device, we include a manufacture letter certifying our specifications. We know it is very confusing out there when it comes to buying a LED device, that is why I encourage you to e-mail or call me with any questions that you might have at email: rita@prolightaesthetics.com   We can be reached by phone at 702-245-4842, M-F, 9-5, Eastern Time Zone.


What is the difference between a hand-held LED device and a LED panel-type device?

This is one of the most confusing and most misleading area of LED technology.   The most important thing to remember here is the farther the light source is from the skin, there is less  light intensity at skin level which means, an ineffective treatment.  It does not matter how many LED diodes there are.  You can have a hundred LED diodes, but if the panel or device is even 1 inch or 2 inches or more from the skin, you are  going to get less light energy at the surface of the skin.  As you hold the LED device farther from the skin the light becomes more diffused and less powerful at skin level.  The reason for this is that LEDs are not collimated like a laser beam. With a laser, the light is the same intensity from the source to the skin level. It is absolutely essential to have the LED at skin level for results.  One of the ways to determine the light output of a light source is with a light meter.  You can measure the light output at the source--- at the LED diode itself, and you can measure the amount of light at the skin level. It is absolutely important to measure the amount of light at skin level and not at just the LED diode( the source). 


What makes ProLight LED diodes different?

All of our ProLight LED devices ultilize ESLDs( Extra Superluminscent diodes) for superior power density for optimum dose and reduced exposure times, for the quickest possible results. Our ESLDs safely provide higher output, as much as 10  times the power of regular LEDs.


Should I base my purchase on testimonials?

Testimonials can be an important factor to consider when making your purchase, however it should not be your only reason to make your purchase.  Be very cautious about reading testimonials on message boards or forums.  All too often, there are salespeople who work for a particular company who want to increase their product sales. One of the most common ways to do this is to pose as an expert giving their opinion rather than facts or  they are just the average person out there that "stumbled" across an amazing ingredient, product,or equipment.  These salespeople try to hype their product on these message boards in hopes that other members on the forum get excited and make that purchase. These salespeople do this because it works.  This is a common practice in internet marketing.   


What is a Laser?

Laser is an acronym for "light amplification by stimulated emission of radiation." Lasers are monochromatic, meaning a single color wavelength; collimated meaning non-divergent; and coherent, meaning light waves that are "in phase" with one another.  For example, two waves are coherent if the crests of one wave are aligned with the crests of the other and the troughs of one wave are aligned with the troughs of the other. Laser light is an extremely well defined beam of light. This beam of light is sharp like a scalpel, sharp, thin and able to do delicate, intricate work.


What is a LED-Light Emitting Diode?

LED's are not coherent nor collimated and generate a broader band of wavelengths.  Non-coherent or non-culminated light is the result of photons moving in random directions at random times, generating random frequencies.  The widely scattered light of an LED is like the pattern of raindrops. Light comes out in a broader, more diffused pattern, composed of a spread of wavelengths from one area of the spectrum.


Are LED's the same as LASER?

No.  The biggest difference between these two is the power output.  Lasers are measured in watts, while LED's are measured in milliwatts. LED's are broad band light, similar to IPL-Intense Pulsed Light treatments.  LED's are non-collimated and non-coherent light sources.


What is ROHS?

ProLight Aesthetics is one of the first companies to incorporate ROHS in all of their light therapy devices.

The ROHS directive is often referred to as "Lead-Free" legislation.  This is not very accurate nickname, because it extends to other pollutants as well.  The proper name for ROHS is:

Directive 2002/95/EC

"The restriction of the use of certain hazardous substances in electrical and electronic equipment" and it applies to the following substances:

         Lead, Mercury, Cadmium, Hexavalent Chromium,
         PBB, PDBE.

In order to comply with the EU ROHS legislation, all of these substances must either be removed, or must be reduced to within maximum permitted concentrations, in any products containing electrical or electronic components that will be sold within the European Union.


Does the ROHS Directive apply to USA manufactured electronic products?

ROHS is a European Union Directive.  Manufacturers in the USA and the Far East will be unaffected by this directive, with regards to the products that they sell outside the EU.

However, it's not that simple for non-EU manufacturers...
Many companies who both operate and manufacture outside Europe, will still eventually sell their products inside the EU.  Many EU-member states/countries are huge markets for both Asian and American companies.  As such, these companies have to make all their products that they sell/export to Europe compliant with the EU ROHS Directive.

Since we do not manufacture our devices within the EU market nor have a dealer/distributor in Europe,  then the Directive does not apply to our products, however, we have decided to manufacture our product to the ROHS Directive to comply with our European customer who purchases our device and will operate our device in their European country.
