THE SCIENCE
How it works.
Silicon dioxide and titanium dioxide are well-documented broadband far-infrared absorbers and re-emitters — published materials research on IR-emissive coatings has measured meaningfully higher infrared emissivity in fabrics coated with these two minerals compared to uncoated material, with the effect holding steady across a range of skin-relevant temperatures.
Raylieve Freeze Gel carries that same mineral pairing — silicon dioxide and titanium dioxide — suspended directly through a fast-absorbing gel base, rather than as filler. Applied to skin, the matrix behaves like a resonant cavity: it captures a portion of the body's own emitted thermal radiation and reflects it back into tissue instead of letting it dissipate into the air.
The gel's cooling sensation is immediate and sensory. The mineral matrix's far-infrared activity is separate and continuous — it keeps working quietly after the cooling fades, for as long as the formula stays on skin.
Because the gel glides on and absorbs quickly, this becomes an easy way to add interactive FIR to a daily routine — no wrap, no sauna session, just direct, targeted application.
