Aug. 10, 2022 -- The FDA has sent warning letters to three companies, including Amazon, for selling mole and skin tag removal products that the agency has not approved..

In addition to Amazon, the other two companies are Ariella Naturals, and Justified Laboratories.

Currently, no over-the-counter products are FDA-approved for the at-home removal of moles and skin tags, and use of unapproved products could be dangerous to consumers, according to the FDA. These products may be sold as ointments, gels, sticks, or liquids, and may contain high concentrations of salicylic acid or other harmful ingredients. Selling unapproved products to consumers violates the Federal Food, Drug, and Cosmetic Act.

Two products sold on Amazon are the “Deisana Skin Tag Remover, Mole Remover and Repair Gel Set” and “Skincell Mole Skin Tag Corrector Serum,” according to the letter sent to Amazon.

The warning letters alert the three companies that they have 15 days to address any violations. However, warning letters are not a final FDA action, according to the statement.

“The agency’s rigorous surveillance works to identify threats to public health and stop these products from reaching our communities,” Donald D. Ashley, JD, director of the Office of Compliance in the FDA’s Center for Drug Evaluation and Research, said in the press release. “This includes where online retailers like Amazon are involved in the interstate sale of unapproved drug products. We will continue to work diligently to ensure that online retailers do not sell products that violate federal law,” he added.

The statement says moles should be evaluated by a health care professional, as attempts at self-diagnosis and at-home treatment could lead to a delayed cancer diagnosis, and potentially to cancer progression.

Products marketed to consumers for at-home removal of moles, skin tags, and other skin lesions could cause injuries, infections, and scarring, according to a related consumer update first posted by the FDA in June, which was updated after the warning letters were sent out.

Consumers and health care professionals are encouraged to report any adverse events related to mole removal or skin tag removal products to the agency’s MedWatch Adverse Event Reporting program.

The FDA also offers an online guide, BeSafeRx, with advice for consumers about potential risks of using online pharmacies and how to do so safely.
