1Introduction
2 paragraphs
This letter is to advise you that the United States Food and Drug Administration (FDA) reviewed your website at the Internet address https://www.isis.gold/ in February and March 2024 and has observed that your website offers numerous chemical peel drug products, including “TCA 100% Trichloroacetic Acid” and “Whitening SA Peels” for sale in the United States. As described below, your “TCA 100% Trichloroacetic Acid” and “Whitening SA Peels” (labeled to contain salicylic acid 30% and various “whitening agents" including hydroquinone) products are unapproved new drugs introduced or delivered for introduction into interstate commerce in violation of sections 505(a) and 301(d) of the Federal Food, Drug, and Cosmetic Act (FD&C Act), 21 U.S.C. 355(a) and 301(d).
The Agency is concerned about potent chemical peel products that are available to be purchased and used by consumers. Such products pose a public health risk because they can cause skin injuries such as burns on the area of application, wounds, pain, swelling, and scarring. FDA has received adverse event reports of injuries involving use of such products, some of which required emergency room care, specialty care from a dermatologist, and/or surgical intervention.

Your “TCA 100% Trichloroacetic Acid” and “Whitening SA Peels”1 products are not generally recognized as safe and effective (GRASE) for their above referenced uses and, therefore, are “new drugs” under section 201(p) of the FD&C Act, 21 U.S.C. 321(p). Subject to certain exceptions not applicable here, new drugs may not be introduced or delivered for introduction into interstate commerce without an approved application from FDA in effect, as described in sections 301(d) and 505(a) of the FD&C Act, 21 U.S.C. 331(d) and 355(a). There are no FDA-approved applications pursuant to section 505 of the FD&C Act, 21 U.S.C. 355, in effect for these products.
