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 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 about LED Light Therapy devices that have multiple colors?

There are hand-held devices and panel type equipment that incorporate multiple different colors, meaning wavelengths, in one device or in one panel.  For example, when someone turns on the hand-held device or panel unit, they may see blue and red colors at the same time. The question that you need to ask, what wavelength is created?  If you understand the color wheel, when someone combines red and blue together, they get purple or violet. What wavelength is that?  What does purple or violet wavelengths do for the skin?  We need to know the wavelength in order to know what skin conditions one can use the light for.  As far as dermatology research shows, there is no skin benefit when applying purple or violet color to the skin.  

Does it matter how many LEDs are in a device?

Many people assume that the more LEDs that there is in a device, that the device is more powerful, thus more effective.  That would be a wrong assumption.  A device can have 100 LEDs, but have low power output. For example, there are devices that have many LEDs, but require the user to hold the device in one spot for 3-4 minutes.  Our devices only require 30-60 seconds in one spot. 

Are panel style LED units better than hand-held LED devices?

People will contact us asking questions about a panel-style LED unit. They mention that they have been told or read on the internet that all you need is one panel to improve the appearance of every skin condition.  They mention that the panel has all "red" color, meaning wavelength, in that one panel and that "red" is all you need.  This is completely misleading and undermines the science of phototherapy.  For the esthetic professional, one needs to use different/various wavelengths, or "colors" to target various skin cells to achieve skin benefits.

A panel type unit has many limitations such as: 

  • one cannot target specific areas of the skin. For example, if you want to target only the chin area for acne. 
  • one cannot customize the Light Therapy skin treatment. Panel units are a one-color-fits-all.  
  • it is impossible to correctly incorporate all of the necessary therapeutic wavelengths in one panel at the correct power output.  One would need at least four different panels to target the various skin chromophores effectively. Having a little bit of blue, a little of red, a little of infrared, and a little of amber in one panel produces a weak, diluted range of wavelengths.  Imagine a box of crayons with all sorts of colors(diluted) rather than a box of all blue crayons(concentrated).
  • if you have multiple skincare professionals in a spa, you would need to have a panel in every treatment room.
  • the loss of "hands-on-wellness" approach by the skincare professional.  Clients are placed under the panel and the professional leaves the treatment room. 
  • panel units are designed for convenience for the operator rather than for maximum, targeted effectiveness for the client who is paying money.

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.

Is the purpose of LED Light therapy for skin rejuvenation to penetrate product into the skin?

LED Light Therapy, which is a broad band light source, is not used to penetrate product into the skin.  IPL, Intense Pulsed Light, which is a broad-band laser light source, has never been used in clinical practice to penetrate creams or other skincare products.  Companies who promote this simply do not understand the principles of light therapy to begin with.  The first law of photochemistry, the Grotthuss-Draper law, states that light must be absorbed for a photochemical reaction to take place.   There is not one single medical Laser/IPL company that uses their equipment to enhance penetration of a cream or serum into the skin. 

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.


What does joule(s) mean?

Quite often, with Phototherapy LED technology, you will read or hear about "joules".  Companies will state that their particular device delivers a certain amount of joules.  Joule is a term that describes energy.   Joule(s) is expressed as this: j/cm2.  Read this way: joules per second per square centimeter.  As you have just read this equation, you may or may not have noticed, this equation is expressed as "joules per second" in a "square centimeter".  We would also need to know, over what period time.
The formula would look like this( example only): 50 j/cm2 for 15 minutes.

The problem for individuals trying to understand this physics formula and how it applies to choosing the best device, is where on-line companies who retail LED technology,  will state that their LED device or equipment delivers a cetain amount of joules, for example,  "100 joules" or  "700 joules" or what have you.      Based on those numbers, the consumer will choose the higher number of joules because it "sounds" more powerful and better.  This is misleading and unfortunate.

There are several issues and marketing problems with this logic.  The problem is this: stating that a LED phototherapy device delivers "100 joules" is not clear and is vague.    Is it 100 joules per second, per minute, per hour, per day, per week? Is it 100 joules in a one inch square area, in a six inch square area, in a one foot square area?  If one wants to inquire about "joules", then one would need to know  how many joules are being delivered over what period of time and size of area.

Continuing on, for example, lets say the company stated their LED device delivers 100 joules per second per square centimeter.(100j/cm2).  To put this in perspective,meaning 100 joules, one could completely destroy( collapse) a leg vein.  That is a LASER, a medical device,  and not LED-light emiiting diodes.  LEDs,  do not and cannot deliver 100 joules per second.  Stating that a LED can deliver 50, 100, 500 or 700 joules per second is terribly misleading.

Here is another marketing example: some companies will take the "joules" number and state that their device is very powerful and delivers "7000 joules".  The average person would  conclude and assume that  7000 joules are being delivered  in "one treatment".  We already know that 7000 joules per second is impossible with LEDs.  We also know that 7000 joules per second cannot be delivered in one square centimeter. With further research, what one finds out is that what they really meant to say was " that a total of 7000 joules have been delivered over 10 treatments , each 45 mininutes long."   Meaning, one treatment did not deliver 7000 joules, but it was a total of 10 treatments, at 45 minutes each equals a total of 450 minutes( 7.5 hours) of treatment time delivering 7000 joules. 

Finally, there are companies, for example, will state a very large joules number, like "12, 000 joules".  With further research, we find that  that  their device is a large panel-style unit and that they are referring to the "12,000 joules" being delivered by the entire panel.  What we want to know is not what the entire panel delivers, but rather how many joules per second are being delivered in one square centimeter over a certain period of time.

Shopping and researching "joules" from one company to another is only effective if one is provided with correct information to begin with.     Remember, if you are researching joules, it is joules per second per square centimeter over a certain period of time.   A more accurate number to "shop" and "compare" with is mW( milliwatts).  We provide the mW/cm2 , rather than just joules, for each of our devices.

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.

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

Majority of the LED Phototherapy devices that are sold through the internet or in retail stores are not manufactured here in the US.      These devices are made with very inexpensive components, incorrrect wavelengths, exaggerated power output, while providing misleading information and testimonials.  Unfortunately, since the advent of the internet, you simply do not know who to trust or believe any more. 

Be believe that if a company advertises or states that their device is Made In America or that they manufacture their device, then it would make sense that they should be able to answer all questions about their device.  They should be able to answer all technical questions and not just the simple questions. They should know everything about their device including on how to best use their device for optimal results.

We believe in providing excellent customer service and every time you call, you will reach an actual person who can answer any questions that you may have.

What makes ProLight LED diodes different?

All of our ProLight LED devices ultilize ESLDs( Extra Super luminscent 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.

How do I register my warranty for my ProLight LED device?

You can go to  Warranty Registration  to complete your ProLight LED device product warranty registration.

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 devices 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 littel 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.

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(W), while LED's are measured in milliwatts(mW). 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 International 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 , 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.
