RadiantU uses two wavelengths of light. 660nm (Red Light) works at the surface to boost circulation. 850nm (Near Infrared Light) reaches deeper, provides soothing heat and calms the inflammation which causes chronic pain.
RadiantU is designed to ease the pain, inflammation, and bloating that come with these conditions. It won't treat the condition itself, but it's built to calm the pain, consistently, without a pill.
We have a 60 day satisfaction guarantee. So if you're not completely satisfied with RadiantU, feel free to reach out to our friendly team anytime at support@radiantustore.com to organise a return.
RadiantU is 100% drug-free with no known side effects for most users. If you are on medication, or have any concerns, we recommend checking with your doctor before starting daily use.
For The Woman Who Needs Deep Relief
For the bad flare-up days. When the heating pad barely takes the edge off. When the painkillers do nothing.
RadiantU is designed to reach the pain where nothing else can touch.
The dual-wavelength technology combines heat therapy with red light therapy to improve circulation and relieve cramps and daily endo pain.
Backed by real relief, loved by real women
Take Back Your Life From Endo
When Painkillers Only Do Half the Job
You deserve better than pills which only work sometimes. RadiantU delivers fast, drug-free relief via red light and heat therapy — it works on your best and worst days.
For Those Days You Can't Get Out of Bed
Whether you're lying down or in fetal position, it keeps working the whole time to relieve your cramps. Relief you can feel in minutes.
Saying NO to Cancelled Plans
You are not your cancelled plans. 15 minutes a day with RadiantU gives you the freedom to start saying yes again.
How does RadiantU work?
1. Deep Pain & Inflammation
Endo pain and bloating start deep in your pelvis, often too deep for surface heat to reach.
2. Wrap It On
Place RadiantU on your stomach or lower back. It sends light straight through your skin.
3. Dual Wavelengths Go to Work
660nm works at the surface to boost circulation. 850nm reaches deeper, providing soothing heat and calming the inflammation that causes chronic pain.
4. Relief
Less pain, less bloating, and you get back control of your day.
What to Expect
Most women feel initial relief within 1 to 3 days of starting RadiantU.
Our customer survey found that with consistent use, flare-ups dropped and average pain fell by 54%.
Because relief that fades in an hour isn't the goal, relief you can count on cycle after cycle is.
What you'd actually want to know
RadiantU uses two wavelengths of light. 660nm (Red Light) works at the surface to boost circulation. 850nm (Near Infrared Light) reaches deeper, provides soothing heat and calms the inflammation which causes chronic pain.
RadiantU is designed for daily use, 15 to 20 minutes at a time. Most people see initial relief within 1 to 3 days, with fuller results building over a full cycle of consistent use.
RadiantU is 100% drug-free with no known side effects for most users. If you are on medication, or have any concerns, we recommend checking with your doctor before starting daily use.
Some users have reported changes in flow with direct use during their period due to the increase in circulation. If you have a heavy-flow condition, we recommend checking with your doctor before starting daily use during your cycle.
RadiantU is designed to ease the pain, inflammation, and bloating that come with these conditions. It won't treat the condition itself, but it's built to calm the pain, consistently, without a pill.
Red light therapy is generally considered safe for pregnancy, but we don't recommend RadiantU until you have discussed this with your doctor.
RadiantU runs on power, not a built-in battery, but we provide an adapter cable that lets you run it off a portable charger, so you're not tied to a wall outlet.
RadiantU works best as an ongoing part of your routine. Most women use it daily, especially in the days leading up to and during their period. It's designed to be part of managing flares long-term.
