Support Radia
Keep the research unsponsored.
We buy the masks we write about — including our competitors' — at full retail, measure them properly, and publish what we find. No affiliate links, no paid placements, no brand approvals. If that is worth something to you, this is where you can say so.
One
Devices on the bench
Every comparison in the Journal starts with a device we paid for ourselves. Measuring wavelength and irradiance honestly means owning the hardware.
Two
Writing that is free
Forty-plus guides on photobiomodulation, dosing and safety, with no paywall and no sponsor deciding the conclusion.
Three
Saying the unhelpful thing
Including when a cheaper device in our own range is the better buy, or when light therapy is simply the wrong tool for the concern.

Secure checkout. Nothing is shipped, nothing expires, and no code is issued — this is a contribution, not a purchase.
Before you contribute
- What does a contribution to Radia pay for?
- Device testing and editorial work. We buy competitor masks at full retail to measure them, and we publish the results in the Radia Journal without sponsorship or affiliate arrangements.
- Is a donation the same as a gift card?
- No. A contribution is not redeemable, carries no code, and cannot be exchanged for a device or store credit. If you want to buy someone a device, shop the collection instead.
- Is my contribution tax deductible?
- No. Radia is a company rather than a registered charity, so contributions are not tax deductible.
- Can I contribute more than the listed amounts?
- Yes. Choose an amount and use the multiplier to increase it — the total updates before you reach checkout.
- Will anything be shipped to me?
- Nothing is shipped. You will receive an order confirmation by email as your record.
