“ULTRA BRIGHT LIGHTENING CREAM Maximum Strength Hydroquinone” [from SKINPRO ULTRA BRIGHTENER HYDROQUINONE product label]

“With a maximum strength of Hydroquinone in the highest allowable amount, the Ultra Brightening Skin Lightener from SkinPro’s Medical Grade Skin Care line of products works fast to eradicate dark spots and prevent future occurrences of hyperpigmentation and uneven skin tone.” [from your website https://www.skinpro.com]

Introduction or delivery for introduction of such a product into interstate commerce is prohibited under section 301(d) of the FD&C Act, 21 U.S.C. 331(d).

Moreover, SKINPRO ULTRA BRIGHTENER HYDROQUINONE is misbranded under section 502(ee) of the FD&C Act, 21 U.S.C. 352(ee), because it is deemed as such under section 505G(a)(4) of the FD&C Act, 21 U.S.C. 355h(a)(4), and because it is a nonprescription drug subject to section 505G of the FD&C Act, 21 U.S.C. 355h, but is not the subject of an application approved under section 505 of the FD&C Act, 21 U.S.C. 355, and does not comply with the requirements under section 505G of the FD&C Act, 21 U.S.C. 355h.

The introduction or delivery for introduction of a misbranded drug into interstate commerce violates section 301(a) of the FD&C Act, 21 U.S.C. 331(a).

_________________________________________

1 On August 29, 2006, FDA issued a proposed rule (71 FR 51146) setting forth a determination that OTC skin bleaching drug products, including but not limited to those that contain hydroquinone as an active ingredient, are not generally recognized as safe and effective.

2 Section 505G(a)(4) of the FD&C Act, 21 U.S.C. 355h(a)(4), authorized FDA to take action before September 23, 2020 to extend the period during which a drug subject to that section may be marketed without an approved new drug application if the Agency determined that such an extension is in the interest of public health. However, FDA did not make such a determination for skin bleaching products
