(Think of it as cooking at turkey at 800 degrees for 10 min rather than 300 degrees for 6 hours. The price has also been changed to $299. Sadick, N. (2009). Visible radiation affects epidermal permeability barrier recovery: selective effects of red and blue light. Majima, K. Watanabe, T. Ueda, H.P. Although a more recent in vitro study by Chen at el (2018) offers very preliminary evidence that LLLT with yellow light at 585nm can help reduce pigmentation. So thats a big lesson to not assume two masks would have the same irradiance if they have the same wavelengths, number of lights, and look identical. The internal temperature may be the same, but the skin of the turkey will be charred in the 800 degree oven). A downside for me is storing this huge mask and having to use it 7 days a week for 20 minutes. ) You can see that since the LG Beauty Mask doesnt have to have the EXACT same specs to be deemed substantially equivalent. If you come across a mask that you are curious about, I recommend identifying the wavelengths used, the irradiance and the treatment time. You will notice in the 510(k) document the LG BEAUTY LED MASK was used as the predicate device (that is how I initially got the specs of the LG Mask! B., Yoon, J. Y., Park, S. Y., Ryu, H. H., Park, B. M., & Suh, D. H. (2013). A. It is not that the device wont be effective, it is just that you really wont be able to gauge whether it is comparable to masks that have been found to be effective. The photobiomodulation zone comprises cells which have absorbed the incident photons, directly or indirectly transferred the photon energy to the cells own energy stores, becoming photoactivated (Calderhead, 2018). (Calderhead & Vasily 2016). So it is best to draw guidance from clinical studies only (later I provide an overview of some clinical studies focused on skin rejuvenation). Please let us know thanks!! A single-blinded randomised controlled study to determine the efficacy of Omnilux Revive facial treatment in skin rejuvenation. A systematic review of at home devices used for nonesthetic purposes (e.g., wound healing, scars, pain, and cognitive function) found that devices finding significant results had irradiances ranging from 8-50 mW/cm2 (Gavish & Houreld, 2019). Lightemitting diodes in dermatology: A systematic review of randomized controlled trials. In a meta-analysis of of low-power lasers in tissue repair and pain control (Enwemeka et al., 2004), 633nm had the largest effect size and 780 had the smallest. Reduction in inflammation due to light therapy is one of the most accepted LLLT effects (Lopes-Martins et al., 2007). Lloyd, A. Prospective randomized study on the efficacy of blue light in the treatment of psoriasis vulgaris. It is best to look for masks with red (at 633nm) ANDNIR(and ~830nm) is where you have the best chance to see results. Photomedicine: Advances in Clinical Practice. The main risks that have appeared in clinical trials were minor and self-resolving and include (Jagdeo et al., 2018). Low level light therapy with light-emitting diodes for the aging face. The efficacy and safety of 660 nm and 411 to 777 nm light-emitting devices for treating wrinkles. I was sad to find out they wont reveal their irradiance. Gupta et al (2014) carried out a similar comparison on wound healing in mice and again found that 660- and 810-nm lasers were effective, while a 730-nm laser was not effective. The optimal clinical irradiance is considered to be around 40150 mW/cm2 (Calderhead, 2018; Sorbellini et al., 2018). Journal of Photochemistry and Photobiology B: Biology, 155, 78-85. A. Available at, unconfirmed, but someone said it had a 2 year warranty, This is not available for those in the states. But you could lay it on your chest, for example, and press and hold it down. Evidence has been also reported indicating the higher efficacy of the combination of different wavelengths in LED therapy than monotherapy (Opel et al., 2015; Jagdeo et al 2018). Photomedicine and laser surgery, 32(2), 93-100. Inflammatory acne lesions contain bacterium, P. Acne, which has porphyrins415nm is the optimal wavelength for porphyrin absorption. Calderhead, R. G. (2018). And 415nm appears to be best and many recommend using it in combination with red or NIR (but blue +red has more evidence). Trelles, M. A., Allones, I., & Mayo, E. (2006). Also I couldnt confirm if the wavelength of the NIR was 760-900 or if it had a more narrow band. Orbit,28(4), 214-218.

My top pick is the Omnilux Contour Mask (see below for more info). 1 year warranty [again, this is surprising given the price I would expect 2 year warranty]. Identical to Light Salon and Current Body. This does not impact your cost. The big downside is that when you use the Red/NIR setting, there are no light coverage on the chin at all (there is only light coverage on the chin with the blue + red setting). A randomized, placebo-controlled, single-blinded, split-faced clinical trial evaluating the efficacy and safety of KLOX-001 gel formulation with KLOX light-emitting diode light on facial rejuvenation. The higher the grade of the LED, the narrower the bandwidth of the emitted photons, allowing LEDs to emit the rated wavelength plus or minus a very few nanometers. (Calderhead & Vasily, 2016). So if you made it through all of those and wanted a cheat sheet that summarizes all of the info (minus the new masks that had been added since my initial post in Jan 2021), here is a summary sheet. Journal of the European Academy of Dermatology and Venereology, 25(1), 49-58. Downsides of this is it uses a bunch of wavelengths that have little to no evidence to support them and it doesnt have NIR.

Lasers in medical science,29(1), 257-265. Does the mask use wavelengths with published scientific evidence showing its effectiveness? Journal of Cosmetic and Laser Therapy,7(3-4), 196-200. Does the device use precise wavelengths (e.g., 633nm) versus wide ranges of wavelengths (e.g., 620-750nm)? However, my contact at Omnilux provided evidence of a, 2 year warranty (I have heard really great feedback from some people that needed to use the warranty.

Karu, T. I., & Kolyakov, S. F. (2005). So really, my TOP picks are Omnilux, Current Body, Light Salon, FaceLite, and Priori. The Higher Dose website shows 830nm for their LED mask. Springer, Cham. British Journal of Dermatology,168(5), 1088-1094. The Journal of clinical and aesthetic dermatology, 11(2), 21. Photodynamic and photobiological effects of light-emitting diode (LED) therapy in dermatological disease: an update. In: Madan V. (eds) Practical Introduction to Laser Dermatology. The results Ive seen from using LED mask for a year, Key Parameters (what you really want to look for when assessing masks), How does Low Level Light Therapy Work? But I want to note that I appreciate how helpful and transparent the contact at Dermashine was nonetheless, I was shocked at how low the irradiance it (I actually thought it was a typo so I confirmed it was 0.5mw/cm2). Journal of Investigative Dermatology, 128(5), 1335-1335. Stating at present, the published literature strongly suggests 830nm for all aspects of wound healing, pain, inti-inflammatory treatment and skin rejuvenation, with a combination of 415nm and 633nm for light-only treatment of active inflammatory acne vulgaris. (2017). Nikolis, A., Bernstein, S., Kinney, B., Scuderi, N., Rastogi, S., & Sampalis, J. S. (2016). Where did you see that it was 880nm? And a major downside in my eyes is that it doesnt include NIR AND it has to be plugged in to use (so it isnt, 2 year manufacturer warranty (you need to register it). Differences in visible lightinduced pigmentation according to wavelengths: a clinical and histological study in comparison with UVB exposure. Clinics in Plastic Surgery, 43(3), 541-550. AlmeidaLopes, L., Rigau, J., Amaro Zngaro, R., GuidugliNeto, J., & Marques Jaeger, M. M. (2001). If the cell has a function, e.g., collagen and elastin synthesis by fibroblasts, it will perform that function more efficiently. Lasers in surgery and medicine,44(3), 218-226. Lasers in surgery and medicine, 50(6), 613-628. If the cell is damaged or compromised, it will repair itself, or be repaired. Clinical, Cosmetic and Investigational Dermatology, 9, 115. Because these products only work if you use them). Then you can compare those specs with this list to see how it stacks up. InLasers in Dermatology and Medicine(pp. The effects of narrowbands of visible light upon some skin disorders: a review. Ok if you want to know even more about the mechanism of action, this section is for you! So unless it is Red and NIR, Red and Blue, or NIR and Blue, you may want to just use different colors separately. improvements in skin tone (Note that only a couple studies have specifically measured pigmentation or melasma, most ask for subjective assessments of improved skin tone), increased elasticity (less evidence for this compared to the the above benefits). Unfortunately, this one doesnt use evidence-based wavelengths AND they have a very wide band (ideally you want a specific wavelength with maybe +/- 15 nm variation,. Photochemistry and photobiology, 84(5), 1091-1099. Finally, the company doesnt provide information about the irradiance (power)and if the mask isnt appropriately powered, then the wavelengths arent going to reach their destination in the skin. I tried to include the most popular masks and any masks that I could find information on in the FDA 510(k) database.

Photobiomodulation or low-level laser therapy. Ultrastructural observations of human skin following irradiation with visible red light-emitting diodes (LEDs): a preliminary in vivo report. Karu, T. I. Light-Emitting Diode Phototherapy.

This is the mask that I used from Nov. 2019-Dec. 2020. Three wavelengths of light that have demonstrated several therapeutic applications are. I have focused this review on skin rejuvenation, but there is a huge body evidence looking at LLLT on wound healing and reducing inflammation. Very expensive mask and the company is very guarded about the wavelengths and power. A controlled trial to determine the efficacy of red and near-infrared light treatment in patient satisfaction, reduction of fine lines, wrinkles, skin roughness, and intradermal collagen density increase. I have updated it with the new price. It uses evidence based wavelengths for red and NIR and has a great irradiance. However, it has high absorption in blood for which it could potentially be useful for some very superficial vascular conditions like rosacea (De Cordova, 2021). And for me the large size is a negative because I always wonder where to store it. Comparisons of findings among studies of LLLT is greatly complicated by use of different wavelengths and dosages. This one is the one I think I would choose if I went with a hard-sided mask because it has great wavelengths, one of the best irradiance, and it has a neck attachment.

If you ask for the power density and the company tells you the energy density instead, you can calculate the power density by using the suggested treatment time (and converting it so seconds). Efficacy of blue light vs. red light in the treatment of psoriasis: A doubleblind, randomized comparative study. 285-337). Wavelengths shorter than 600nm tend to scatter, rather than to penetrate deeply into the body tissues. So if you are more likely to consistently use a 3 min mask versus a 10 min one, I would get the Qure mask (and I would stick with the red setting for the primary mode to consistently use). Pigment cell & melanoma research, 27(5), 822-826. (Mechanism of Action), Things to keep in mind (including notes about blue wavelengths), Some IG posts Ive done on the LED use, results Ive seen, and. (2016). Res. Press Esc to cancel. Photobiomodulation stimulates fibroblast proliferation, collagen synthesis, growth factors, and extracellular matrix production by activating cellular mitochondrial respiratory pathways (Ablon, 2018). Serrage, H., Heiskanen, V., Palin, W. M., Cooper, P. R., Milward, M. R., Hadis, M., & Hamblin, M. R. (2019). Bhat, J., Birch, J., Whitehurst, C., & Lanigan, S. W. (2005). When that gap gets large that indicates low quality LED). This is why you really want to find out the irradiance before buying! One thing to keep in mind is that the irradiance and fluence used in vitro studies are often different from those used in clinical studies. So I personally think 2 year warranties are the way to go with LED masks. The combo of 633nm red light and 415nm blue light is recommended because the red light also tackles inflammation and appears to improve the efficacy on noninflammatory lesions (Greaves et al 2015). IEEE Journal of selected topics in quantum electronics, 22(3), 348-364. Omnilux and FaceLite are almost identical except they differ in terms of the, Here is where it gets complicated and super nuancedOf the 7 masks that are all made by the same manufacturer, the manufacturer told me that all 7 have the exact same wavelengths and irradiance. (2013) Low-level laser (light) therapy (LLLT) in skin: stimulating, healing, restoring. Red light can help this process because it stimulates collagen synthesis and fibroblast formation, anti-inflammatory action, energy production in mitochondria, and DNA repair (Barolet, 2018; de Freitas & Hamblin, 2016; Hamblin, 2016). (2016). In a meta-analysis of LLLT in wound repair, energy densities from 19 to 24 J/cm2 were found to be more effective than energy densities at or below 8.25 J/cm2 (Woodruff et al., 2004). This should be the bare minimum requirement. A higher irradiance often means a shorter treatment time. Adjunctive 830 nm light-emitting diode therapy can improve the results following aesthetic procedures. This next figure from Kim and Calderhead (2011) further illustrates the confirmed mechanisms of action for the three main endpoints of 830 nm LLLT (633 nm has beneficial effects as well), namely wound healing, the anti-inflammatory response through acceleration and quenching of the post-wound inflammatory phase and pain attenuation. 2013 Mar;32(1):41-52. This is the most gimmicky LED maskapparently this one also has rose quartz crystals. So while it doesnt have my ideal wavelengths, using the mask consistently is what is most important. In LLLT, the irradiance and wavelength is analogous with the medicine, and the energy density is the dose. Another downside is that you get 4 uses before needing to charge it again (that is really low and would be annoying in my opinion). Regulation of skin collagen metabolism in vitro using a pulsed 660 nm LED light source: clinical correlation with a single-blinded study. Light emitting diodes technology-based photobiomodulation therapy (PBMT) for dermatology and aesthetics: Recent applications, challenges, and perspectives.

This one has a lot of unnecessary wavelengths (personally, I would Just use the 630nm setting on this) and it has some wavelengths (439, 450-460nm) I would actively avoid using. I started using this mask in Jan and I also have been using. How can you avoid wasting your money? But right now it is available on.

But onebigdownside of this mask is that it doesnt have NIR. This ones parameters are pretty good (this is the mask that FaceLITE used as the predicate device in their 510(k) submission.) The beneficial effects of LLLT are governed by the ArndtSchultz law, which says that cells will respond differently to varying levels of irradiance (mW/cm2) or radiant exposure (J/cm2). (2008). Some companies like to highlight the number of wavelengths used, but often those additional wavelengths have very little or no published work to back up the claims of the manufacturer (and they seem more like a marketing gimmick than anything), and a careful consideration of the wavelength/penetration ratio will rule out many of the shorter visible light wavelengths (Calderhead, 2018). Another major downside is that it doesnt include NIR. Begin typing your search above and press return to search. In Handbook of Low-Level Laser Therapy (pp. Lasers in Surgery and Medicine: The Official Journal of the American Society for Laser Medicine and Surgery, 39(2), 180-188. Non-invasive peri-orbital rejuvenation: Radiofrequency dual radiowave energy source (rf) and light emission diode system (LED). In order for LED masks to actually be effective, the wavelength and irradiance are key. Then it uses orange (590-620nm) which doesnt have evidence to back up its claims, And the other major downside is that it doesnt have Near Infrared. Lima, A. M. C. T., da Silva Sergio, L. P., & da Fonseca, A. D. S. (2020). Photobiomodulation via multiple-wavelength radiations. Karu, T. I. Journal of Photochemistry and Photobiology B: Biology,88(1), 51-67. This matters because research has found that wavelengths between 700-770 have been reported to not have any significant activity (Gupta et al., 2014; Karu, 2010; Wu et al 2012). De Cordova, J.

Weinstabl, A., Hoff-Lesch, S., Merk, H. F., & Von Felbert, V. (2011). Van Tran, V., Chae, M., Moon, J. Y., & Lee, Y. C. (2021). Avci P, et al. Photochemical & Photobiological Sciences,18(8), 1877-1909. It has been suggested that oxidative stress is an early step in the process of cellular damage incurred by blue LED exposure even at low doses (10 J/cm2) (Nakanishi-Ueda et al., 2013). This comes with a little neck (NOT chest, just neck) attachment, which is a nice perk. The masks in my comparison represent only a small selection of the LED masks available. First, we convert the treatment time to seconds (10*60=600). Red and Near infrared (NIR) have a number of different mechanisms of action, but two main ones involve: Through these mechanisms, LLLT is thought to help increase the skins ability to resist the photoaging processes. Whilst the perceivable dangers of LLLT are mainly related to retinal damage (both clinician and patient) and skin burn (mainly related to shorter UV wavelengths), the safety of LLLT is well documented in a number of standards such as US Code of Federal Regulations, American National Standards Institute and the International Standards Manual, and other laser safety books and review articles [21, 22]. Hamblin, M. R. (2016). Ideally, you would want to see 633nm), the blue wavelength is better (405nm to 420nm wavelength, 415nm is the ideal), but blue light comes with downsides to consider and eye protection is necessary which this doesnt provide. That means that 90% of the photons are at the rated wavelength and will therefore optimally target wavelength-specific chromophores at that wavelength. They report their power density, but if they didnt here is how we could find it. If LED therapy is administered several times prior to a UV insult, a mechanical trauma such as a CO2 laser treatment or a surgery, one may prevent undesirable consequences such as sunburn, postinflammatory hyperpigmentation (PIH), or hypertrophic scarring, respectively. Barolet goes on to talk about those applications, ocular symptoms (typically with blue light), discontinue sessions if any side effects occur, Many companies cite evidence from in vitro or animal studies. A difference of even 5nm from the peak can in some cases dramatically lower the action potential (Calderhead, 2018). It is the power density of a beam that will determine more than anything else (apart from wavelength) the magnitude of the bioeffect in the target tissue (Calderhead, 2018). If the wavelength is not correct, optimum absorption will not occur (and without absorption there will be no reaction). Barolet, D. (2018). It has been reported for a continuous wave system that shorter irradiation times with a higher intensity (irradiance) got significantly better results in first passage human gingival fibroblast proliferation. Out of the flexible LED mask options I would pick Omnilux because it is the most affordable (after coupon code) out of the Shape A masks and for all the other reasons I outlined above. Photomedicine and Laser Therapy,22(4), 323-329. The use of wavelengths in LLLT at 400nm or lower should be utilized in practice with extreme caution. (Serrage et al., 2020). ~590 nm (yellow): it has effect only in the epidermis with poor penetration into the dermis. New addition to list as of 6/11/2021. Calderhead, G., & Tanaka, Y. Medical Laser Application, 21(3), 165-175. I was sent the mask by the brand to try (with no string attached) and I loved it. 47 (2013) 774780. In the red wavelength, this uses 620nm -750nm (thats a HUGE span not great at all.

Lasers in medical science,35(2), 307-316. In an animal study, Blue light (430510nm) delayed the barrier recovery, whereas red light (550670nm) accelerated it. Irradiation with a wavelength of 415nm can destroy the P.acnes but it doesnt address the associated inflammatory problem. I would pass on this one because the Omnilux Contour and FaceLITE are identical but cheaper. For example, to repair damage from UV rays, your skin needs to be able to repair cellular and DNA damage (which is similar to what it does during wound healing). Journal of Dermatological Science,89(1), 11-18. But a higher irradiance isnt always better. This includes The Guidelines for Skin Exposure to Light in the International Standards Manual (IEC-825) which states that an exposure of less than 200 mW/cm2 is safe, and the marketing and the use of therapeutic LLLT is approved by the Food and Drug Administration. T. Nakanishi-Ueda, H.J. But in terms of where to buy it, it can be a little hard to find. A study to determine the effect of combination blue (415 nm) and near-infrared (830 nm) light-emitting diode (LED) therapy for moderate acne vulgaris. I believe the company is based in Australia, so for those in the US, the shipping will be $19.95. The term blue light can refer to a relatively wide range of wavelengths from violet (390425 nm), indigo (425450 nm), royal blue (450475 nm), blue green (475500 nm)and they have had very different results. The dark art of light measurement: accurate radiometry for low-level light therapy.

Opel et al (2015) Light-emitting Diodes: A Brief Review and Clinical Experience. Exact action spectra for cellular responses relevant to phototherapy. (2005). Fournier N, Fritz K,Mordon S. Use of nonthermal blue (405-to 420-nm) and near-infrared light (850- to 900-nm) dualwavelength system in combination with glycolic acid peels and topical vitamin C for skin photorejuvenation. Woodruff, L. D., Bounkeo, J. M., Brannon, W. M., Dawes, K. S., Barham, C. D., Waddell, D. L., & Enwemeka, C. S. (2004). On the lower threshold, I think 5mW/cm2 is a good bottom value, but I would prefer something closer to 40 since the majority of the studies used 55mW/cm2 (and it also means that it is more likely that I can wear the mask for 10 minutes versus 30 minutes, which some of the masks with the lowest irradiance suggested). Some of the limited studies using yellow light were not able to be replicated by different researchers. Light stimulus will be insufficient to trigger a cellular function if it is delivered below the recommended dose and will inhibit activation of these responses if a dose higher than indicated is delivered. In Part 2 of this blog I want to summarize all of the growing areas of research because there were far more that I couldnt cover in one post. Ng, J. N. C., Wanitphakdeedecha, R., & Yan, C. (2020). I was happy to see this had a good irradiance and used Red and NIR in the right wavelengths (and that the company disclosed it but that was, 2 year warranty (BUTbe sure to register your device within ONE MONTH of buying it or the warranty is void. International journal of cosmetic science,38(4), 325-345.
