No way to know unless you measure its output spectrum, but as long as it's mostly IR, it shouldn't.
Question though, why would you do that? I don't see the difference between using this or applying any other heat source.
I'm interested to know if the LEDs will be pointed inwards or outwards...
Inward. Outwards would be just weird
Biohacking self-improvement light therapy supposedly to reduce inflammation. It has an immediate and noticeable effect on me, strong enough that I doubt it's just placebo. It started when I suffered long-term low-level pain in my ankle several months after twisting it (I hate aging!), and read how light exposure at the right wavelengths could help. My ankle did improve, although of course this might have been just natural healing. Then I started to consider other possible benefits of light therapy such as reducing inflammation in the brain. See this video.
I have very high prior against light therapy on forehead or scalp reducing inflammation in brain. There is thick bone between skin and brain! Blood supply to skin on head is separate system to blood supply to brain. Maybe beneficial effect on skin, creates healing particles in blood, blood carry them to brain. But have to go long way round. Also cross blood-brain barrier.
Phototherapy for SAD is different, more plausible, because proposed mechanism is direct via photonic stimulation of retina to influence biorhythm-generating processes. Signal passes in to brain by nerves, not blood.
But rigorous self-experimentation is good idea with low-risk treatment. So I wish you good luck even though I count low chance of success, except for placebo effect.
