The described biological mechanism is based on photobiomodulation, where red and near-infrared wavelengths are absorbed by mitochondrial cytochrome c oxidase, potentially promoting ATP production. Systematic reviews, such as the one published in 'Seminars in Cutaneous Medicine and Surgery', indicate encouraging evidence for skin rejuvenation and collagen synthesis via this cellular stimulation. It is important to note, however, that while randomized controlled trials (RCTs) show positive results regarding texture and fine lines, actual efficacy depends heavily on fluence, dosage, and regularity of use. The term 'longevity' remains ambitious and must be nuanced: while local benefits to the skin are documented, systemic effects on overall longevity are still largely being explored in the laboratory and lack robust clinical evidence in humans. Dr. Youn relies on a recognized biological mechanism, but the extrapolation to overall health benefits warrants a cautious approach.

What the graded evidence says

Evidence: C

Effect: skin appearance and intradermal collagen density — Controlled trial (n=113): red/near-infrared light significantly improved skin complexion and feeling, reduced fine lines, wrinkles and roughness, and increased ultrasonographically measured collagen density vs untreated controls. No comparable human evidence for systemic 'mitochondrial recharge' or whole-body energy.
Measured on: adults seeking skin rejuvenation (single controlled trial); systemic claims unstudied

The skin benefits come from limited trials and device output varies, so keep expectations modest. The systemic 'mitochondrial energy' story is mechanistic hype without strong human evidence — Noli reframes it as skincare, not a metabolic upgrade.
