What Is Photobiomodulation? A Simple Guide to the Science Behind Laser Healing
What is Photobiomodulation (PBM)?
Photobiomodulation (PBM), also known as low-level laser therapy (LLLT) or red light therapy, is a safe, non-invasive treatment that uses specific wavelengths of red and near-infrared light to stimulate healing within the body. Originally developed in the 1960s, PBM has grown into a clinically validated therapy used across fertility, pain management, post-surgery recovery, hormonal balance, and more.
The Science: How Light Supports Healing
PBM works by delivering light directly to your cells, where it's absorbed by the mitochondria — the cell's energy centre. This triggers a boost in ATP (adenosine triphosphate), your body's natural energy currency. More energy means faster repair, reduced inflammation, and better cellular communication.
PBM also enhances blood flow, reduces oxidative stress, and modulates immune function — all essential for recovery, hormonal health, and fertility.
What Can PBM Help With?
Fertility support (egg quality, uterine lining, hormone balance)
Chronic inflammation and pain
Hormonal conditions like PCOS or endometriosis
Post-operative healing
Fatigue and low energy
PBM vs LLLT vs Red Light Therapy — What’s the Difference?
PBM refers to the therapeutic process itself
LLLT is a term often used for lower-power clinical lasers
Red Light Therapy is often used in the wellness world and may refer to LED devices
While all three terms overlap, true PBM uses medical-grade lasers (like the GigaLaser™) capable of deep tissue penetration for maximum effect.
What to Expect from a Session Sessions are non-invasive, pain-free, and relaxing. You’ll lie comfortably while a laser is placed over the treatment area. Most sessions take 20–30 minutes.
