Low Level Laser Therapy Ireland, What It Is and Where to Access It
Low level laser therapy (LLLT) is the clinical term for therapeutic light therapy using red and near-infrared wavelengths at doses designed to stimulate cellular repair rather than cut or destroy tissue. It is now more commonly called photobiomodulation (PBM).
What Is Low Level Laser Therapy
The term low level refers to the dose, not the quality or effectiveness of the therapy. The light is applied at energy levels that activate the body's own biological repair processes without causing thermal damage to tissue. LLLT has been studied since the 1960s and is now used in clinical settings across Europe, Japan, the United States and Ireland.
LLLT, PBM and GigaLaser, Understanding the Terms
Low level laser therapy, photobiomodulation and red light therapy all refer to the same underlying mechanism. The GigaLaser is a medical-grade LLLT system that delivers red (650nm) and near-infrared (830nm) light across a large treatment area, up to 500cm² in a single session, penetrating up to 12cm into tissue.
At GigaLaser Ireland, every protocol is individually designed based on your condition, the depth of tissue being targeted and the clinical evidence for your specific situation.
Conditions LLLT Supports, What the Evidence Shows
Strong clinical evidence
- Knee osteoarthritis, 8 to 12 sessions typical.
- Fibromyalgia, benefits measurable at 6-month follow-up in the strongest RCT.
- Tendinopathy, meta-analysis of 25 RCTs.
- Oral mucositis, formally in oncology guidelines.
- Post-exercise recovery, systematic review of 46 RCTs.
Growing evidence
- Fertility support, informed by Danish clinical protocols and the Ohshiro 2012 study.
- Neuropathic pain, confirmed by a 2025 systematic review.
- Endometriosis, LLLT reduces pelvic inflammation and supports nerve sensitivity regulation.
How Many LLLT Sessions Are Needed
The number of sessions depends on the condition. Surface conditions, 5 to 8 sessions. Knee osteoarthritis, 8 to 12. Fibromyalgia, 12 over 4 weeks. Neuropathic pain, 15 to 20. Fertility support, weekly sessions over 3 to 4 months.
LLLT for Practitioners, Referral Information
GigaLaser Ireland welcomes referrals from GPs, physiotherapists, gynaecologists and other healthcare practitioners. No formal referral letter is required, a brief clinical summary is helpful. We provide clinical progress updates to referring practitioners with patient consent.
FAQ
Frequently asked questions
What is low level laser therapy?+
LLLT is therapeutic light therapy using red and near-infrared wavelengths at doses that stimulate cellular repair without causing tissue damage. It is also called photobiomodulation or red light therapy.
Is LLLT available in Ireland?+
Yes. Medical-grade LLLT is available at GigaLaser Ireland in Sandyford, Dublin 18 and Edenderry, Co. Offaly.
What is the difference between LLLT and high-powered laser therapy?+
High-powered surgical lasers cut and destroy tissue through heat. LLLT uses light at doses that stimulate cellular biology without damaging tissue. Non-invasive, painless and no downtime.
How many LLLT sessions are needed?+
Surface conditions, 5 to 8 sessions. Knee osteoarthritis, 8 to 12. Fibromyalgia, 12 over 4 weeks. Neuropathic pain, 15 to 20. Fertility, weekly sessions over 3 to 4 months.
Can I be referred for LLLT by my GP in Ireland?+
Yes. GPs and physiotherapists can refer directly to GigaLaser Ireland. No formal referral letter is required, a brief clinical summary is helpful.
Is LLLT safe?+
Yes. Non-invasive, painless and no downtime. Compatible with most medical treatments. Specific contraindications are assessed at initial consultation.
