After a six-month-long investigation, a 33-year-old Mankato woman is facing charges for providing body modification and running a body art business without a license.

The Minnesota Department of Health says 33-year-old Virginia Nguyen was performing microblading – a tattooing technique that creates hairlike strokes to make thin eyebrows appear fuller – at Infinity Nails Spa and Salon on Cherry Street.

The state health department sent Nguyen several notices, telling her she needed to be licensed in order to perform the service, but the criminal complaint shows that she didn’t respond to them or return calls from the Mankato Department of Public Safety.
