Is a warranty provided with Photizo?
If my Photizo isn’t working properly, what should I do?
In the unlikely event that you need to return your Vetcare device and you have purchased it in the UK, please review our Photizo Light Therapy – Troubleshooting Guide
Is Photizo Light Therapy a Laser device?
No, Photizo is not a laser device. The diodes in Photizo devices are LED (Light Emitting Diode) which are different to laser diodes. Laser diodes produce pinpoint beam (coherent) light which can damage eyes. LED diodes produce a more diffuse/spread out light (incoherent – like any normal light bulb or torch).
The manufacturers and distributors of Photizo never describe Photizo as laser although we hear that some users may call Photizo a laser device which is incorrect terminology.
Do I need Laser goggles/protective eyewear?
No because Photizo is not a laser device. The diodes in Photizo devices are LED (Light Emitting Diode) which are different to laser diodes. Laser diodes produce pinpoint beam (coherent) light which can damage eyes. LED diodes produce a more diffuse/spread out light (incoherent – like any normal light bulb or torch) so this does not cause damage to eyes. However we advise users do not stare directly into the lens when the Photizo is lit up because the red wavelength is extremely bright and this may temporarily affect vision (similar to looking at any bright light for a while).
What is the difference between the various Photizo models?
Across the handheld Photizo Home Care range which includes Vetcare and Blush, there is no difference in the wavelengths which the diodes produce (633nm and 850nm) or output power. The only difference is the timed dose which determines the level of dose applied to the tissue. Photizo Vetcare produces a 31 second dose compared with Photizo Blush which is a 16 second dose. The strength of dose in Vetcare is 3x stronger. Therefore the Blush model dose is more appropriate for superficial application, eg. used on face for improving skin tone/texture and anti-aging effects. Studies show the strength of dose is an important parameter to consider for improving the effectiveness across a different range of conditions.
The professional units work on a similar principle to the Photizo Home Care models, the strength of the dose changes between the different settings. Ideally a user might want to apply a lower dose for superficial tissue whereas a stronger dose may be more appropriate for deeper conditions & pain relief.
What are the side-effects of Light Therapy?
Photizo has been optimised to deliver an optimal dose of near-infrared light to treat several conditions, if used once daily or once every two days. Applying Photizo Light Therapy more than once a day will not cause any discomfort or pain, but may result in slower wound healing. In addition, some patients with painful conditions report a slight increase in pain when using light therapy, but this usually passes in a few minutes and is followed by a pain relief effect.
Will Light Therapy cause cancer?
Light therapy does not cure or cause cancer. However the user guide precautions state:
Do not use light therapy on any cancer or suspected cancerous mass. Light therapy cannot cause cancer – no mutational effects have been demonstrated for LED-based light therapy devices in any medical or scientific literature to date. The light produced by Photizo Vecare in infrared and near infrared, non ionizing light and is at the opposite end of the light spectrum to harmful ultraviolet (UV) light. The Photizo devices are, however, useful in treating patients from many of the side effects of cancer treatment, such as mucositis (a painful side effect of radiation therapy).
Can Photizo be used during pregnancy?
The effects of Photizo have not been tested on pregnant women or animals. While the fetus cannot be negatively influenced by light, as the penetration depth of the Photizo is only 12 mm depending on the type of tissue in application area, we would not recommend using Photizo on areas proximal to the developing fetus.
Can Light Therapy affect the thyroid gland?
While there are no known side effects related to LED-based light therapy, the thyroid gland is a sensitive gland and very close to the skin surface, so treatment directly over the thyroid should preferably be avoided. A slight increase in thyroid activity has been reported in one study using LED light therapy. We suggest you place a light permeable object over the thyroid when treating in or around this area.
Can Photizo be used to relieve arthritis pain?
Photizo has an analgesic effect in most patients suffering from various forms of degenerative joint diseases such as arthritis. Not only does Photizo relieve pain, but it also stimulates the replacement of chondrocytes, thereby assisting in the rebuilding of joints.
Can Photizo be used on or by epilepsy sufferers?
Some studies suggest that pulsed or strobed visible light at frequencies in the 5-10 Hz range can cause epileptic attacks. Photizo does not pulse in the 5-10 Hz range, but epileptics (like all other persons) should avoid looking directly at the light beam emitted from the probe for preventive measures.
Can Photizo be used on children or small animals?
No harmful effects have been demonstrated when treating growth plates in young animals. Young children and animals can be treated safely with Photizo, provided the protocols are strictly adhered to.
Can Photizo be used on or by cancer patients?
Light therapy does not cause or promote cancer. However, Photizo is useful in treating many of the side-effects of cancer treatment such as mucositis, a painful side-effect of radiation therapy.
Can Photizo be used on or by diabetic patients?
Yes, Photizo was designed originally for use in healing venous ulcers in diabetics. Diabetic patients having slow healing or non-healing wounds, and individuals suffering from loss of sensation in the hands or feet tend to benefit tremendously. However, it is important to treat wounds, cuts or scratches immediately following injury to ensure quick healing and to lessen the risk of infection.
Do I need to have training to use Photizo?
No, Photizo devices have been specifically pre-programmed with evidence-based doses to enable any level of user to use correctly and effectively to obtain faster healing outcomes and reduce pain or to use proactively. If a qualified practitioner requires training on the subject of phototherapy to improve background knowledge of this modality or training is required for insurance purposes, there are various options such as a CPD Phototherapy course offered through an independent training provider.
Is there a course on phototherapy if I would like to know more?
Yes, there is currently a course offered by Jo Rose Holistic Therapies. Contact us for the next available date or check out our Events page. We may be planning to offer more courses around the UK and if you would like to be added to our mailing list for phototherapy courses, please contact us.
