Absolute Contraindications

• Eyes: The laser beam must never be aimed at the eyes, and appropriate protective eyewear is required for everyone in the treatment area to prevent serious internal eye damage.

• Malignancy: Avoid treating areas of known or suspected cancer.

Relative Contraindications

• Photosensitivity: Patients taking photosensitizing medications or those with conditions that increase light sensitivity should avoid treatment. 
• Hemorrhage: Be cautious with patients on blood thinners or with active bleeding, as the therapy could potentially worsen a hemorrhage. 
• Pacemaker: Avoid treating over areas near the heart if the patient has a pacemaker.
  
• Tanning: Recently tanned skin increases the risk of burns and pigmentation changes. 
• Epilepsy: Patients with seizure disorders should be treated with extreme caution, as certain light frequencies could trigger a seizure.

• Growth Plates: Caution is advised when treating over areas of bone growth centers.
