Laser therapy safety depends heavily on the type of laser, its application, and the expertise of the practitioner. Generally, when performed by a qualified professional, laser therapy is considered safe and effective for various medical and cosmetic purposes. However, like any medical procedure, it carries some risks.
Understanding Laser Therapy Safety
Laser therapy encompasses a wide range of applications, from surgical procedures to non-invasive treatments like low-level laser therapy (LLLT) or photobiomodulation (PBM). The safety profile varies depending on the type and intensity of the laser used.

Low-Level Laser Therapy (LLLT): Studies show LLLT has a low complication rate. https://pubmed.ncbi.nlm.nih.gov/26984240/ This type of therapy, often used for pain management and wound healing, is generally considered very safe. Even Class 1 and Class 2 lasers, like those found in barcode scanners and laser pointers, demonstrate daily safe usage. https://www.aaha.org/resources/laser-therapy/

Surgical Laser Procedures: While surgical lasers can offer benefits like faster recovery times compared to traditional surgery, they still carry risks such as bleeding, scarring, pain, and infection. These risks are comparable to those of open surgery. [Reference from 09-Sept-2023] However, the laser light beam itself does not pose health risks to the patient or medical team.

Potential Risks and Side Effects
While generally safe, laser therapy can have potential side effects, depending on the type of procedure:
- Bleeding: More common in surgical procedures.
- Infection: A risk with any invasive procedure.
- Pain: Can occur during and after treatment.
- Scarring: Possible, especially with surgical interventions.
- Changes in skin color: A potential side effect of some skin treatments.
These risks are usually minimized by proper patient selection, skilled practitioners, and adherence to safety protocols.
Conclusion
Laser therapy's safety is directly tied to its application and the expertise of the practitioner. When performed correctly, it is a safe and effective treatment option for numerous medical and cosmetic applications. However, potential risks should be discussed with a healthcare professional before undergoing any laser treatment.
