What is the controversy with hydroquinone?

The controversy surrounding hydroquinone stems from its safety concerns and regulatory status. While it's an effective skin-lightening agent, its long-term use has been linked to potential risks, including bluish-gray skin discoloration and skin irritation. Due to these risks and regulatory changes associated with the CARES Act, the FDA banned over-the-counter hydroquinone products in 2020. While Tri-Luma (fluocinolone / hydroquinone / tretinoin) is the only FDA-approved product containing hydroquinone, compounded formulations or prescription-only hydroquinone creams may still be available under medical supervision. View original source
