The 43-year-old "Modern Family" star claimed that the Venus Concept used her name and likeness without her permission to promote its products through multiple advertising materials, reported US magazine.
The lawsuit stated, "Vergara tried the Legacy treatment, but ultimately did not like it, finding that it was a waste of time and money with little in the way of any results."
It also stated that "(Vergara) would not use it again, and certainly would not endorse it nor agree to appear in an international advertisement campaign to promote it," and she didn't "recommend the Venus Legacy product or services."
She has been battling with the company for more than a year now.
