LASER Therapy (LLLT): Healing at the Cellular Level
July 19, 2026 · 4 min read · by Avanish Chandra · 32
Low-level laser therapy uses light energy to calm inflammation and speed up tissue repair — here is how and when we use it.
Low-Level Laser Therapy (LLLT), also called cold laser therapy, uses focused light of a specific wavelength to stimulate healing inside cells without generating heat or damaging tissue.
How it works
The light energy is absorbed by the cell's mitochondria, boosting energy production (ATP) inside injured cells. This speeds up the natural repair process, reduces inflammatory chemicals, and can reduce pain signalling in the treated area.
Conditions we commonly treat with LASER
- Tendinitis (tennis elbow, Achilles tendinitis)
- Plantar fasciitis and heel pain
- Post-injury soft-tissue swelling
- Slow-healing wounds and scar tissue
Sessions are quick (5-10 minutes), completely painless, and are usually combined with exercise therapy for the best long-term result.
