Photobiomodulation
LED
Precisely calibrated wavelengths of non-thermal light — red, near-infrared, and blue — absorbed into skin at the cellular level to accelerate healing, reduce inflammation, stimulate collagen, and address acne at its biological source.

01
What it is
Photobiomodulation delivers light to skin at wavelengths and fluences calibrated for biological effect rather than thermal damage. Each wavelength reaches a different tissue depth and engages a different biological target: red light (620–680 nm) penetrates the mid-dermis and activates fibroblasts and mitochondrial pathways; near-infrared (780–900 nm) reaches deeper tissue and supports anti-inflammatory signaling; blue light (415–420 nm) interacts primarily with the epidermis and targets porphyrins produced by Cutibacterium acnes.
A single treatment head can deliver a combination of wavelengths in the same session, addressing multiple skin priorities simultaneously.
02
How it works in tissue
The foundational mechanism is the same across wavelengths: photons are absorbed by chromophores in skin cells — most notably cytochrome c oxidase in mitochondria — triggering a cascade of downstream biological responses: increased ATP production, release of growth factors, upregulation of collagen and elastin gene expression, and modulation of inflammatory cytokines.
The clinical consequence of this cellular activation is multi-dimensional: wound healing accelerates, post-treatment recovery shortens, new collagen is laid down over weeks, and acne lesion counts decrease through reduction of the porphyrin-photosensitizer interaction in the sebaceous follicle.

Where it earns its place
LED photobiomodulation is the upgrade an appointment deserves: added at no discomfort to the patient and minimal operator input, it accelerates healing post-procedure (reducing visible downtime for injections, microneedling, or resurfacing), supports standalone skin-clarity and rejuvenation programs, and manages acne across the maintenance gaps between more intensive treatments. It is also one of the few modalities supported by evidence across all Fitzpatrick skin types without pigmentation risk.
