UVB vs UVA - UVB light therapy mimics the sun's natural ultraviolet B (UVB) rays, which are essential for the skin to produce vitamin D. Natural sunlight consists of approximately 95% UVA and 5% UVB. Enyrgy Vitamin D Light Therapy devices, however, are engineered to deliver about 95% UVB and only 5% UVA, ensuring a safe and effective therapy. When the skin is exposed to UVB light, it initiates a natural process that converts a cholesterol precursor into vitamin D3, the active form of vitamin D that our body can use. This efficient process reduces the need for prolonged sun exposure, thus minimizing the risk of skin damage such as sunburn.
The Enyrgy Vitamin D Light Therapy lamp is specifically designed to emit UV light that is approximately 95% UVB and just 5% UVA. In contrast, fluorescent UV lamps, even those marketed as “UVB” for vitamin D production, can emit over 60% UVA. Some other narrowband UVB LED products may emit as much as 15%-30% UVA. There are several reasons for this discrepancy:
- LED Emission Band: UVB light ranges from 280nm-315nm, while UVA light ranges from 315nm-400nm. The peak wavelength of the LED used in the device dictates how much light falls outside the UVB range.
- Quality Control: LEDs can vary in quality, with margins of error in peak wavelengths of 5-10nm or more.
Enyrgy Vitamin D Light Therapy lamps undergo rigorous quality control, with 95% of sourced LEDs being rejected to ensure only the top 5% are used in the manufacturing process of the patented LED card. This meticulous process guarantees that the light emitted is approximately 95% UVB. No other device on the market is manufactured to such exacting standards, ensuring the highest level of safety and efficacy in Enyrgy Vitamin D Light Therapy.
Eye-Safe Design– Long-term exposure to UV light can increase the risk of developing chronic eye problems, such as: Cataracts, Pinguecula, Pterygium (surfer's eye), Macular degeneration, Eyelid cancers, and Corneal damage. By being completely enclosed and used on the abdomen and lower back, the Enyrgy device is designed to completely eliminate any possible exposure to the eyes to the user. Furthermore, special sensors inside the device, will automatically turn the device off if the user backs away from the light during an active session.
To safely use ultraviolet light, the exposure time, distance, and dosage must be precisely controlled. Enyrgy Medical Advisor doctors developed the Minimum Erythema Dose (MED) protocol to deliver the optimal ultraviolet exposure tailored to each user's unique skin type.
Consistent Dosing - A critical aspect of optimizing for safety and efficacy is consistency in the amount of light reaching the body each time the device is used. With UV light, if you are too close to the source, you increase the risk of injury and if you are too far from the source, you may not receive the proper intensity needed. The Enyrgy Vitamin D Light Therapy device is designed such that the user presses their body up against the edge of the device – therefore the distance from the light source is exactly the same each and every time the device is used. Only the Enyrgy device provides for such precise and consistent dosing.
Uniform Irradiance – Light emitted from a light panel or fluorescent lamp will have significant variations in intensity (irradiance) that reach various parts of the body. The part of the body perpendicular to the center of the device will receive a high intensity of light, whereas parts of the body not perpendicular to the center of the device will receive a very low intensity of light. In contrast, the Enyrgy device provides an extremely uniform intensity of light across the surface area of the skin exposed. This is due to its specific shape and reflective surface on the interior of the device. Stated differently, to optimize for safety and efficacy, one should minimize the difference between the PEAK irradiance and the AVERAGE irradiance that reaches the body – the Enyrgy Vitamin D Light Therapy device is the ONLY device on the market that does that.
The Enyrgy App is a key differentiator, as it is how users operate the device. The app first
administers a Fitzpatrick skin-type quiz to determine the client's skin type. Based on the skin type, the app provides a specific treatment regimen, starting at 1 minute per side (front and back), gradually increasing to a maximum of 2 minutes per side. Additionally, the app ensures clients can only treat themselves once per calendar day and records the history of all treatments. It also collects a medical release form for every treatment session.
