The DPL Therapy FAQ – Frequently asked questions and answers about DPL® deep penetrating light and comparison to other top brands. And, the uses and benefits of Infrared photo rejuvenation LED light panels
Below are many questions and answers about the DPL® Therapy’s deep penetrating photo rejuvenation and infrared LED light system. The Q & A's are broken down into 3 catagories; skin, pain and general.
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... The DPL® has 174 LED lamps, including 154 infrared. The LightStim has 72 lamps, including only 36 infrared. Treatment time for the whole face is nine minutes with the DPL®. The recommended treatment time for the LightStim is four minutes per area, and since the diameter of the light is only 2 1/2 inches it takes about an hour 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. I've used both lights (Lightstim for one year and DPL since mid-June, 2006) and have experienced faster and better results with the DPL system.
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. 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 $400.USES A BENEFITS OF INFRARED LED LIGHT THERAPY FOR SKIN CARE
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. I 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, I have seen reports of hyper-pigmentation and scars fading over time from the use of LED lights.
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.
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.
NOTE REGARDING BLUE LIGHT: We made the decision to not sell a blue light because it has been shown to damage the eyes if used without the proper protection. If you decide to purchase a blue light, be sure the merchant supplies 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?
Q. What is the best wavelength of infrared light for skin rejuvenation? And what is the importance of joule ratings?
A. There are over 30 commercial 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. We feel that the NASA study is the most independent and accurate of the studies, so that was the one used to develop the DPL System. The NASA study 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. Our DPL System utilizes 154 infrared (880nm) LEDs and 20 red (660nm) LEDs.
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. Our DPL® Therapy System reaches 4 joules/cm2 on the skin, like the NASA study specified, in 9 minutes. 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 less than 1 minute, but the machine costs tens of thousands of dollars.
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. Can LED light treatment be used on someone who has been treated recently with Botox® injections?
A. I believe that although the light would cause no harm to the tissue, since it has a regenerative effect it might shorten the life of the paralyzing effect of Botox, so the person might want to avoid using the light around the injected areas until the Botox wears off.
Q. Will the DPL® System work for stretch marks and loose skin on the stomach?
A. I'm not aware of any of our customers who have used the light on stretch marks, so I forwarded this question to the manufacturer. Here is their reply: "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 I was selling a different light (smaller and less powerful) I 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.
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 where applied.
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. 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 I'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 light we sell—the DPL® Therapy System—is 9 minutes a day for the first 8-10 weeks, then nine minutes two-three days a week after that. The light timer is factory set at 17 minutes and can not be change. The 17 minutes is recommended for the relief of pain and swelling.
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.
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. The DPL® Therapy System's user manual says to use the system for 17 minutes. I thought the treatments were 9 minutes?
A. The recommended time to treat pain is 17 minutes. However for skin rejuvenation you can do either two 9-minute treatments or one 17-minute treatment. After 2 months of use most people are able to reduce usage to one 9-minute treatment every day, or 3-4 times a week.
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.
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 DPL® System is built to last over 5 years with daily use and the LED bulbs should not burn out within that time. The bulbs are built into the two panels and are not user-replaceable, but should replacement of a panel be needed please contact me at firstname.lastname@example.org
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 afterward may help calm down your skin.
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. I 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 Technologies, LLC recommends consulting your physician prior to using the DPL® Therapy System.
Q.Where is the DPL® Therapy System made?
A. It's made in the USA.
