Skincare company Murad Inc. said it filed a lawsuit Monday against CVS Health Corp. alleging the retail pharmacy chain has been selling its products without the El Segundo firm’s permission.

The unfair business practices suit filed in Los Angeles Superior Court claims CVS has no business relationship with Murad and secretly diverts its products from unknown sources, according to the skincare firm.

Murad said that many of the products sold by CVS have been stripped of the skincare firm’s quality-control tracking features such as hologram protection seals and unique batch codes used to help prevent tampering or the distribution of counterfeit goods.

It appears that CVS is selling more than 40 of the skincare firm’s products on CVS.com and in certain brick-and-mortar CVS stores across the country, according to Murad.

“Our relationships with authorized retailers, such as Sephora, Ulta, Nordstrom, Massage Envy, and numerous spas and salons around the world, validate our mission to deliver high quality merchandise to the consumer through trusted retail outlets,” General Manager Richard Murad said in a statement. “We will continue to take unrelenting legal action against anyone who threatens Murad’s brand integrity or otherwise poses a risk to the public by defacing the quality-control features we put on our products.”

A spokesman for CVS, Mike DeAngelis, said in an email that the company had not been served and would have no comment.

Murad executives would not comment further on the suit. The firm said it’s seeking an injunction against CVS.
