Photobiomodulation

Photobiomodulation (PBM) is the current scientific name for what has also been called low level laser therapy (LLLT), low-power laser therapy, biostimulation, or simply cold laser. All the names describe the same idea: delivering light at wavelengths and intensities that produce a biological response in tissue, without heating or damaging it.

How it works

Light in the red and near-infrared range penetrates tissue more deeply than other parts of the visible spectrum. Within the cell, photons are absorbed by chromophores in the mitochondria — the cell's energy producers. This absorption is associated with changes in cellular energy production (ATP), nitric oxide release and cell signalling. In plain terms: the light gives cells a stimulus, and cells respond.

Because the response happens at the cellular level, the same technology appears across many fields — skin work, tissue recovery, lymphatic treatment — with the difference lying in the settings used and where the light is applied.

What it feels like

Very little, honestly. The device rests against the skin and delivers light — no heat, no sound, no vibration, no downtime. It is completely non-invasive, and treatments are commonly experienced as relaxing.

Kylie's training and equipment

Kylie is a Lymph Drainage Specialist and Cold Laser Specialist who has worked with this technology for over a decade, including device training with Multi Radiance (2014, 2015) and Raincorp (2015). In her clinic, PBM appears within skin treatments, tissue recovery work and lymphatic care — usually combined with hands-on techniques rather than used alone.
