The U.S. Food and Drug Administration (FDA) has warned the public to avoid using certain over-the-counter topical products marketed to relieve pain before, during, or after specific cosmetic procedures, including microdermabrasion, laser hair removal, tattooing, and piercing.
The agency has issued warning letters to six companies responsible for manufacturing these products, citing violations of federal law due to containing higher concentrations of lidocaine than permitted.
