Development Stage

Early Stage

Focused ultrasound research is in the laboratory phase and is not yet available for patients.

Clinical Trials

Focused ultrasound for this condition is being researched in clinical trials.

International Approval

Focused ultrasound is approved to treat this condition outside the US. Patients can seek commercial treatment at participating international sites.

FDA Approved

The US Food and Drug Administration has approved focus ultrasound for this condition. Patients can seek commercial treatment at participating sites.

FDA Approved

Focused ultrasound for this condition has been researched in clinical trials. However, at this time, we are not aware of any open clinical trials.

Focused Ultrasound Therapy 

Focused ultrasound is a therapeutic technology that could transform the quality of life and decrease the cost of care for patients with solar lentigo. This novel technology focuses beams of ultrasound energy precisely and accurately on targets deep in the body without damaging surrounding normal tissue. 

How it Works 
Where the beams converge, focused ultrasound produces several therapeutic effects that are being evaluated. The energy from high intensity focused ultrasound impacts the targeted tissue and causes tightening of the tissue and an alteration of the underlying tissue mechanics that results in an increased tension of supporting structures as well.  

The primary options for treatment of solar lentigo include laser therapy, cryotherapy, and chemical peels. For certain patients, focused ultrasound could provide a noninvasive alternative with possible increased efficacy to existing medical therapy.  

Advantages 

  • Focused ultrasound is noninvasive, so it does not carry added concerns like surgical wound healing or infection.  
  • Focused ultrasound can reach the desired target without damaging surrounding tissue. 
  • It can be repeated, if necessary. 

Clinical Trials 

At the present time, there are no clinical trials recruiting patients for focused ultrasound treatment of solar lentigo.  

The Foundation updates these pages regularly, but with the increasing number of clinical trials, we want to be sure that our audience has the latest information available. Therefore, we also added the website search information for the above trials. If you click here, it will take you to the latest information available from https://www.clinicaltrials.gov/.  

Regulatory Approval and Reimbursement  

Focused ultrasound treatment for solar lentigo is not yet approved by regulatory bodies or covered by medical insurance companies.
