Dermalux LED

No. Therapeutic LEDs are narrow-band. 633 and 830 nm overlap cytochrome c oxidase absorption; 415 nm overlaps C. acnes porphyrins. A broad infrared heater is warmth. This is photochemistry at named photoacceptors, which is a different object from a bathroom bulb.

ATP and blood flow can move in a sitting. Collagen I transcription and a drop in MMP-1 are repeated-exposure effects. Wunsch and Matuschka measured matrix changes after a course, not after a single glow, and that is the number to keep because it has histology behind it.

Neither. LED is a device occupying cytochrome c oxidase and porphyrins. BPC-157 and TB-500 are research ligands in other models — VEGFR2/NO and G-actin. Different inputs, overlapping tissue questions. We stock the ligands. The clinic owns the lamp.

Complex IV of the mitochondrial respiratory chain: copper-A, copper-B, haem a and haem a3. It reduces oxygen to water and is the working photoacceptor for red (~633 nm) and near-infrared (~830 nm) photobiomodulation. Nitric oxide binds it reversibly; photons can photodissociate that NO, after which ATP rises.

415 nm is the Soret-band overlap with coproporphyrin III in C. acnes. 633 and 830 nm sit on Karu’s cytochrome c oxidase action spectrum, at two tissue depths. Dermalux Tri-Wave puts three photoacceptor stories on one head so a clinician can choose.

In human skin, a course of red or red-plus-near-infrared LED phototherapy increased ultrasonographic collagen density and, on biopsy, collagen and elastin, and reduced MMP-1 (Photomed Laser Surg 2014; 32: 93–100). It is not a Dermalux-brand trial. It is the human matrix direction the 633/830 pair lives in.

C. acnes makes coproporphyrin III. Photons at ~415 nm excite that porphyrin; reactive oxygen then damages the organism. Host mitochondria are a poor target at that wavelength and depth. Different job from the red/near-infrared pair.

Too little fluence, nothing happens. Too much, and you inhibit the same enzyme or turn a signalling ROS pulse into damage (Arndt–Schulz, as the photobiomodulation field inherited it). Clinic devices exist to sit on the useful shoulder. Write milliwatts per square centimetre and joules, not just minutes.

No. It is a gastric 15-mer with a nitric-oxide and VEGFR2 literature, stocked as a characterised research sequence. The appointment is LED phototherapy, booked with eLIVEate. Patriot takes no commission on that diary, and nobody is reconstituting a peptide into the head.

Phototype is a filter here, not a chromophore the device requires. Darker epidermis absorbs more of the 633 nm on the way in; 830 nm still travels. Blue on a melanised follicle is a separate pigment-risk conversation the clinician owns. There is no plasma-style bronze eschar and no social week off.
