Recovering from cosmetic surgery can be challenging. Swelling, bruising and pain often extend downtime and affect comfort. Photobiomodulation (PBM), also called low-level laser therapy (LLLT), is an evidence-based, non-invasive method that accelerates recovery by reducing inflammation and stimulating tissue repair.
Recent research, including a clinical trial investigating 830 nm PBM after eyelid surgery, highlights its effectiveness in reducing complications and supporting smoother healing outcomes.
How photobiomodulation works
PBM delivers targeted wavelengths of red or near-infrared light into tissues. This light energy is absorbed by mitochondria, increasing cellular energy (ATP) and promoting repair. Key benefits include:
-
Reduced inflammation through modulation of pro-inflammatory signals
-
Improved circulation and lymphatic drainage for less swelling
-
Accelerated wound healing via faster cell turnover
-
Enhanced scar quality with better collagen organisation
Clinical evidence for post-surgery recovery
-
Blepharoplasty: A 2025 study demonstrated PBM significantly reduced swelling and improved recovery after eyelid surgery.
-
Oral and facial surgery: Meta-analyses confirm PBM lowers pain, swelling and muscle stiffness, showing its potential across multiple surgical settings.
-
General wound care: Reviews highlight faster wound closure and improved tissue outcomes under PBM.
Benefits for cosmetic surgery patients
PBM can make a noticeable difference after procedures such as liposuction, facelifts and breast surgery by:
-
Minimising post-operative swelling for greater comfort.
-
Reducing pain levels and reliance on medications.
-
Speeding wound healing and lowering infection risks.
-
Improving scar outcomes for smoother cosmetic results.
Treatment approach
-
Timing: PBM is most effective when started in the first week after surgery.
-
Frequency: Sessions are typically daily or every other day during the initial 1–2 weeks.
-
Wavelengths: Red (630–680 nm) and near-infrared (800–850 nm) are most effective for deep tissue healing.
Devices such as the Pulsed Low-Level Laser Therapy unit are designed to deliver these wavelengths safely and effectively.
Safety and considerations
PBM is low risk and non-invasive, but precautions include:
-
Avoiding use over active cancer sites
-
Eye protection for periocular treatments
-
Care in patients taking photosensitising medications
When applied correctly, PBM is safe and well tolerated, with few side effects.
Faster Healing with Laser Therapy
Laser therapy through photobiomodulation is a powerful adjunct to traditional recovery care. It reduces swelling, speeds wound healing and improves patient comfort after cosmetic procedures such as liposuction, facelifts and breast surgery.
For patients and clinics interested in integrating this evidence-based approach, the Pulsed Low-Level Laser Therapy device provides a practical and accessible solution for recovery support.
