“I just wanted to thank you and let you know that I have had amazing results from the DPL System. While I initially purchased the unit for skin rejuvenation, I had excruciating TMJ when I began use in April. My jaw suddenly stopped hurting and I have not had ONE incident of the searing pain since I started treatment!!! It has also brightened up my skin and given me a refreshed look, plus it’s plumped my lips…sweet!” —P.F., Kentucky

Q. What is the difference between the original DPL Therapy System and the DPL II? The DPL II is more powerful than the original DPL Therapy System, primarily because it has more LED bulbs. It also provides enhanced treatment of surface issues due to the larger number of red LEDs. Plus the amber LEDs help with redness, swelling, inflammation and related conditions (such as rosacea), as well as treatment of burns (such as sunburns).

Q. How long will I have to use an LED light before I see results? 
A. Some people see results in as little as a few days and others take a month or two to notice a change. Various physical conditions, age, skin condition, diet, alcohol consumption, prescription drug usage, smoking, exercise, and other factors influence the rate of improvement. The effects of LED light are often subtle at first, since unlike lasers, peels and other ablative treatments, LED light does not damage the skin to force it to regenerate. Your results will improve the longer you use the light; so though you should see improvement in 60 days, you should see a much more significant change after you’ve been using it for 6 months or a year. If you are using the panel system, to accelerate results you can try placing the panels directly on your skin instead of sitting in front of the light on the stand.

Q. How do infrared LED lights for home use compare to the photo rejuvenation light treatments done in spas and salons?
A. The concept and technology are the same. The difference is in cost and convenience. One photo rejuvenation treatment in a spa or salon typically costs $50-$200, and it’s usually recommended that you get a series of 5 to 10 treatments several times a year. With home-use photo rejuvenation lights you can enjoy unlimited treatments in the convenience of your own home for less than $500.

Q. Is infrared LED light safe for sensitive skin?
A. If you have very sensitive skin it might be a good idea to start with a shorter treatment time and work up to the full treatment. Also, be sure to start with clean skin… lotions could heat up and cause a problem. If there is any redness or discomfort after treatment, applying a damp cloth afterwards may help calm down your skin. Note that the DPL II should be less irritating to sensitive skin than the original DPL Therapy System.

Q. Are there any medical precautions?
A. See precautions page.

Q. Will infrared light help my rosacea?
A. The amber bulbs in the DPL II help reduce redness, swelling and inflammation, and often help reduce the symptoms of rosacea. With the original DPL Therapy System results were mixed…some rosacea patients benefited from using the light, but a few found they could not use it. If you have rosacea we recommend going slow at first to see how your skin reacts. (see sensitive skin tips above)

Q. What is the difference between the DPL Therapy System and the LightStim?
A. In our opinion the most important differences are the number of lamps, light wavelengths, treatment time and results, see comparison chart for details. Treatment time for the whole face is nine minutes with the DPL. The recommended treatment time for the LightStim is three minutes per area, and since the diameter of the light is only 2 1/2 inches it takes quite a while to treat the whole face. Since results will only be achieved with regular use, this time difference can be a critical factor for busy people.

Q. I heard about a red light called Tanda Red on Dr. Oz. How do the DPL Therapy System and DPL Nüve compare to the Tanda?
A. As in the above comparison to the LightStim, the DPL Therapy System has many more bulbs…192 in the DPL panel system vs. 20 in the Tanda Red. The DPL Nüve hand-held system has 60 bulbs, again many more than the Tanda Red. More bulbs means greater results, in a shorter period of time. Compare Amazon ratings…DPL Therapy System = 4.5 stars; Tanda Red = 2.5 stars (3/23/11).

Q. I have seen some improvement using a Beurer Softlaser. How do other lights compare?
A. The Beuer® light has only one 660 nm lamp. Most other home-use lights have larger surface areas and utilize multiple wavelengths. This means you get the benefits of multiple wavelengths over a larger area in a shorter period of time.

Q. Is photo rejuvenation safe?
A. YES! It has been proven in numerous studies that LED photo rejuvenation does not harm the human body in any way. The light waves are safe for any age, color, or skin type. The light energy delivered cannot burn sensitive skin tissue.

Q. Does LED light therapy hurt? 
A. NO! Unlike many other anti-aging treatments, LED light therapy is gentle, painless, safe, noninvasive and nonabrasive. There have been no reports of adverse reactions.

Q. Is it safe to use an infrared LED light while pregnant?
A. We have been told by one manufacturer that it would be OK to use an infrared LED light on the head, neck, face, arms and legs during pregnancy, but as a precaution they recommend not using it around the abdomen. LED Therapies, LLC recommends consulting your physician prior to using the DPL Therapy System.

Q. Do you ever discount your DPL Therapy System?
A. Because of our incredible money-back guarantee, we occasionally have returned units that are cleaned, tested and repaired if needed, then sold as refurbished units at a discounted price. If you are interested in a refurbished system, contact us to see if we have any in stock. Also, we occasionally run unadvertised specials. Contact us to find out if we are currently running a special.

Q. Do you have to replace light bulbs in the DPL Therapy System? If so, how often do they need changed and how much are the replacement bulbs?
A. The bulbs are built into the panels and are not user-replaceable, but the system is built to last over 5 years with daily use and the LED bulbs should not burn out within that time.

Q. I just turned on my system for the first time and not all the bulbs are lit up. Is my unit defective?
Infrared light is not visible to the human eye, so the majority of the bulbs will not appear to be lighted when you turn on your system. To check whether the infrared bulbs are working you can view the lighted panels through a digital camera.

Q. Will LED light therapy help with acne or blemishes? 
A. Although the anti-aging photo rejuvenation lights were not designed specifically to handle acne and blemishes, the light waves stimulate the skin’s natural healing process which helps in the treatment of acne, pimples and blemishes. However, the blue DPL Nuve was specifically designed for treatment of acne, as was the Claro which utilizes IPL (Intense Pulsed Light) to speed healing of individual pimples.

Q. I’ve been looking for information on the LED light treatments that I’ve been receiving from my skin care specialist. Is there a significant difference between the benefits of blue and infrared/red light? 
A. The choice of light depends on what you are trying to accomplish. BLUE light comforts and soothes skin, and has anti-sensitive functions. It is used clinically to treat acne, as it is absorbed by bacterial acne, resulting in a toxic environment for the bacteria. RED light stimulates and activates skin cells and promotes blood circulation. VISIBLE red light penetrates to a depth of about 8-10 mm, and is beneficial in treating problems close to the surface such as wounds, cuts, scars, trigger and acupuncture points, and is particularly effective in treating infections. INVISIBLE red light (infrared) is the longest wave length, and penetrates to a depth of about 30-40 mm, which makes it more effective for bones, joints, deep muscles, etc. Infrared light is absorbed by the skin and used as a source of energy to stimulate fibroblast cell activity in the skin, which increases the production of collagen and elastin—the proteins responsible for your skin’s tone and elasticity. Most infrared LED lights produce both red and infrared wavelengths, and are effective for rejuvenating aging skin as well as treating acne and blemishes. Amber light, which was added in the DPL II, helps with redness, swelling, inflammation and related conditions; as well as treatment of burns.

NOTE REGARDING BLUE LIGHT: Blue light has been shown to cause damage to the eyes (macular degeneration) if used without proper protection. If you decide to purchase a blue light, be sure to use the proper eye protection. And if you have a teenager using it for acne be sure he/she actually uses the eye protection!

Q. I’ve been receiving red light therapy to firm my skin and reduce wrinkles and I’ve seen a slight improvement after many sessions, but not as much as I’d like. Will infrared work better?
A. It’s very likely you will see better results with infrared light. As explained in the last question, infrared light penetrates much deeper than red light, so it is able to reach the layer of skin where collagen and elastin are produced.

Q. What is the best wavelength of infrared light for skin rejuvenation? And what is the importance of joule ratings?
A. There are many systems on the market using similar and different LED wavelengths. Most companies say that the specific wavelengths they are using are *the best* so it’s hard for the consumer to determine what is true. The NASA study, upon which the DPL Therapy System was based, used three LED wavelengths: 670nm, 728nm and 880nm. The 880nm (infrared) proved to be the most effective when tested alone in both 3T3 fibroblast DNA synthesis and osteoblasts DNA synthesis.

However, the real key to achieving results is the energy delivered (joules/cm2), not the particular nm of the LEDs. Many units have variable energy output that goes as high as 150 joules/cm2. The DPL II Therapy System reaches 31 joules of energy per cm² in 8 minutes (3.9 joules/cm²/minute). Some more powerful systems used by physicians and spas reach this level more quickly, but these machines are too expensive for home use and can be purchased only by licensed professionals. For example, the GentleWaves system reaches the required output in under 1 minute, but the machine costs tens of thousands of dollars.

Q. While doing research on the Web I read that yellow light is effective for skin rejuvenation. What are the benefits and results of infrared and red light therapy vs. yellow?
A. We am aware of some testing done comparing yellow light to red and infrared wavelengths. Without question, red and infrared were found to work better for skin rejuvenation.

Q. Will infrared LED light help with hyper-pigmentation (age spots) or scarring?
A. YES, we have seen reports of hyper-pigmentation and scars fading over time from the use of these lights.

Q. Will infrared LED light help with dry skin? 
A. YES, using infrared LED photo rejuvenation lights according to directions will help normalize dry skin.

Q. Will infrared LED light help with thinning hair? Will it help re-grow hair? 
A. We have read reports of accelerated hair growth and stimulation of dormant hair follicles with the use of infrared LED light.

Q. Can LED light treatment be used on someone who has been treated recently with Botox® or fillers? 
A. Reply by the manufacturer of the DPL System: From our research and review of studies, using LEDs typically does not cause an increase in dissipation of fillers or Botox. Filler dissipation is usually a result of poor insertion. Also, everyone’s skin is different and dissipation will not be the same for every person. But it appears that in most cases using LED therapy will not cause fillers or Botox to dissipate more quickly. Normally a person should wait a couple days to let the fillers settle a bit, then start using the LED’s slowly. If there is bruising at the injection site the LED light will help with healing. If someone is hesitant to use the light in an area where there have had botox or fillers they can cover that area with a thick material, such as a rolled-up towel.

Q. Will the DPL System work for stretch marks and loose skin on the stomach?
A. According to the manufacturer “We have customers who are using the system on the stomach and for stretch marks, and I know that is it very helpful with scaring… the age of the scar tissue will determine the time required to see results.” Also, when we were selling a different light (smaller and less powerful) we heard about a woman who used the light on a scar while she was laid up in bed for 10 days. She said the scar diminished a great deal during this time by treating it for 15 minutes a day.

Q. Will the DPL System help with psoriasis?
A. The red and infrared lightwaves of the DPL System increase circulation and help put moisture back into the skin, which benefits those with psoriasis. One of our customers told us “I’ve been using the light, per the instructions, and find the psoriasis spot I mentioned to you is almost healed. The light is actually accelerating the healing process. Normally it takes about a week or so to heal on its own. It has been only 3 days.”

Q. Can DPL Therapy help with other types of problems?
A. In addition to skin rejuvenation, infrared and near-infrared (NIR) light often helps with the temporary relief of minor muscle and joint pain; arthritis and muscle spasms; relieving stiffness; promoting relaxation of muscle tissue; and temporarily increasing local blood circulation.

Q. What will I notice during and after treatment?
A. Different sensations are possible with use of the system. You may experience a sensation of warmth, relief of pain, a calming or soothing effect, and you may find you achieve a greater range of motion.

Q. When will I feel better or see positive results?
A. Factors such as age, sex, level of fitness and various physical conditions can affect how quickly the treatment helps. In cases where a condition has lasted for many years (chronic) it may take longer to notice a benefit.

Q. How often can I use the DPL System for pain and healing?
A. For pain relief, the maximum use of the system should be four 9 minute treatment sessions, with 12 hours separating the first two 9 minute treatments.

Q. How close to the skin should I hold the DPL System?
A. For best results the panels should be as close to the skin as possible, and they may be placed directly on the skin. Center the panel(s) over the main area of pain for maximum effectiveness.

Q. I have arthritis in my hands. Will I be able to use the system?
A. Yes, the DPL System was designed with the arthritis sufferer in mind, and hands can be held in front of the panels on the stand, or the panels can be placed on or beneath the hands.

Q. I have used my system for a couple of days; why am I still hurting?
A. Keep in mind that this system serves as therapy for minor discomfort; it is not a miracle drug or pain killer and is not intended to replace medication prescribed by your physician. Consult your physician if the pain persists or intensifies, as this may be a symptom of other conditions that need attention.

Q. Why doesn’t the system get hot?
A. The DPL System isn’t designed to generate heat, but some people report that it gets warm or they feel warmth in their skin, and this is normal. When you follow the recommended usage guidelines, the LEDs should not get uncomfortably hot.

Q. I had a huge bruise on my leg so I tried my LED light on it, and it went away much more quickly than bruises typically do. I’m now using it on the bruises that my daughter gets on her legs from climbing on playground equipment. Does it make sense that the light works on bruises?
A. NASA research found that infrared LED light accelerates healing, so yes, it may help bruises heal faster.

Q. Does the light work through clothes?
A. Some materials can prohibit the system from delivering the treatment most effectively. If possible, use without clothes on the treatment area.

Q. How long do you need to apply the LED light for skin rejuvenation?

A. Recommended treatment time varies among different brands of LED lights, and we’ve seen these recommendations change over time as more data is collected. Generally, for the quickest results, daily use is recommended. The recommended treatment time for the DPL II Therapy System is 8 minutes/day.

Q. The DPL System instructions say that after 4-8 weeks of using it twice a day, I’m supposed to use it only 2-3 times a week. Won’t that slow the rejuvenation process down? What will happen if I continue using it daily?
A. It’s recommended to use the system twice a day at the beginning to build up circulation and stimulate your skin, which will cause it to respond to the LED light. You can continue twice a day usage up to 10 weeks if you would like. After that you should be able to use the system just 2-4 times per week and your skin should continue to respond nicely. Some of our customers have continued to use the system daily after 10 weeks, and we have heard of no ill effects. However, should you notice redness, irritation, peeling, or other unusual effects we would recommend cutting back on usage.

Q. How far away should I place the light from my skin?
A. The light intensity becomes weaker the further away it is from your skin, so it’s best to use the light very close to your skin. It is fine if the DPL Therapy System touches your skin; in fact, a number of customers have reported fast, enhanced results when they started laying the panels directly on their skin.

Q. The DPL Therapy System’s user manual says to use the system for 17 minutes. I thought the treatments were 8 minutes?
A. The recommended time to treat pain is 17 minutes. However, for skin rejuvenation you can do just one 8-minute treatment. After 2 months of use, most people are able to reduce usage to one 8-minute treatment every day, or 3-4 times a week.
