Frequently Asked Questions
Do Usuie devices ship internationally?
Yes, of course! We ship to all countries worldwide using only fully insured global carriers such as UPS/FedEx/DHL/TNT/etc.
Should I wear any eyewear when I use the red light device?
Eyeglass is necessary. Do not stare directly into the LEDs. Eyeglasses are included and we recommend you wear the Eyewear when you use NIR mode.
Will the treatment interfere with or be affected by any medications I use?
If you use medications such as Tetracycline, Digoxin (used for heart irregularities), and photosensitizing drugs (e.g., tranquillizers, sulfa drugs, oral anti-diabetic drugs, antidepressants, and steroids), please consult your physician before using Red Light.
How often should I use the red light device?
It is recommended to start with a commitment of 20 minutes 3-5 times per week for the first 1-4 weeks. Then 2-3 times per week for the following 4-12 weeks, and finally 1-2 times per week to maintain results.
What are the differences between red and near infrared light?
The wavelength is different. Red light is absorbed by surface tissues and cells and delivered at 660nm. Near-infrared light is invisible to the human eye and penetrates deeper tissues provided at 850nm.
Is Red Light Therapy similar to tanning?
No! During a red-light therapy session, you will not get a tan, as you are not exposed to damaging UV rays.
Why do the Near Infrared LEDs look like they're not working?
Red light belongs to the higher wavelength component of the visible light spectrum, whereas infrared light, which has a longer wavelength than red light, is invisible to the naked eye. Although it is not seen when used, it works for our body, such as reducing the side effects of cancer treatment and speeding up the recovery time.
Can both the red and the near infrared lights be used at the same time?
Yes, you can turn on the Red and NIR lights at the same time if you need. Just press the two buttons.
What is the EMF (electromagnetic field)? Is it safe?
Usuie devices are designed to have low EMFs. You won’t be exposing yourself to unwanted EMFs, because we’ve integrated advanced components into our devices to serve as a barrier.
Is red light therapy FDA approved?
Red light therapy devices have received FDA approval for wound healing and for chronic joint pain. Other applications of red light therapy have strong clinical and scientific evidence but are still being researched for FDA approval.
When will I see results from red light therapy?
For most people, visible results from red light therapy take at least 2 weeks or 6 total sessions. Depending on the condition you are treating, you may not see results for months. Think of red-light therapy like a gym workout- it takes more than one session before you notice a difference.
What is the difference between at-home and in-office red light therapy?
The only major difference between at-home and in-office red light therapy is the strength of the beam. Just like other dermatology procedures, medical professionals can use a higher-strength form of treatment safely. However, you may see similar or greater results at home because you can use your therapy device more frequently.
Is at-home red light therapy safe?
Yes, at-home red light therapy is safe. The risks of at-home red-light therapy are not different from the risks of red-light therapy at a dermatologist’s office. Side effects are rare and mild. If you are following the instructions of your device properly, your injury risk will be very low.
