Frequently Asked Questions
What effects can The Ruby produce?
The Ruby can help with recovery, increased energy, and vitality, among other things. It uses both red and near-infrared light to provide a daily dose of red light therapy. The Ruby targets specific areas and promotes the body's natural processes, giving a sense of well-being. Many users experience improved sleep, a stronger immune system, and faster recovery. The systemic effect of red light therapy means that the treatment benefits not only a specific area but the entire body. Simple and effective – perfect for integrating into your daily routine, no matter where you are.
How long does it take before I notice an effect?
Use it for 20-40 minutes per day. Everyone responds to the treatment at different speeds, but continuous use is the key to good results.
Can I experience any side effects during use?
No, the light emitted from The Ruby is safe, without known side effects.
What is the difference between passive and active red light therapy?
Passive and active red light therapy offer two distinct approaches to improving health and well-being through light treatments. Passive red light therapy involves a lower dose of light over a longer period, where the body can absorb the light systemically without focusing intensely on a specific area. This method creates a slow, steady effect that supports the body's natural processes over time. Active red light therapy, on the other hand, focuses on a higher dose over a shorter period and is particularly effective for treating specific areas that require deeper penetration, such as muscles and joints. The Ruby offers a unique form of passive treatment, perfect for discreet occasions when you want an invisible dose of red light therapy. Thanks to its subtle design, you can gain the benefits of low-dose treatment without the light being visible, allowing you to wear The Ruby during the day and continuously support your body and well-being.
