U.K. retailer Tesco has issued an urgent recall for its Kind & Pure facial cleansing wipes, one of the store’s most popular beauty products. Past shoppers who have purchased the wipes have been advised to return the product to a store for a full refund after detecting a ‘microbiological risk’ that could pose serious harm to customers’ health. Specicially, during a test, a bacteria called Pluralibacter gergoviae was detected, which can be particularly harmful for people with sensitive skin.

“As a precautionary measure, Tesco is recalling various Tesco Kind & Pure Facial Cleansing Wipes due to unsatisfactory microbiological testing and detecting the presence of Pluralibacter gergoviae, which can make these products potentially unsafe for use,” Tesco said in the product recall statement.

Pluralibacter gergoviae usually carries a low health risk, but it can also cause severe infections in people with weakened immune systems or chronic illnesses. It has been linked to respiratory diseases, eye infections, urinary tract infections and sepsis, according to UK testing laboratory Melbec Microbiology.

Tesco Kind & Pure 25 Facial Cleansing Wipes 163g and Tesco Kind & Pure Radiant Facial Cleansing Wipes Vitamin C 25 Pack 159g are included in the recall.
