Q: What is hydroquinone?

Q: How does hydroquinone fade dark spots?

Q: Is hydroquinone safe?

Q: Can hydroquinone cause cancer?

A: Unfortunately, this is misinformation spread online. There are zero reported cases of hydroquinone causing cancer in humans. In fact, millions of people have been using it for nearly 100 years. Hydroquinone is a plant extract, and you intake 300 times more hydroquinone daily from coffee or tea than from topical use. HQ is even safer with topical use under the supervision of our board-certified dermatologists. Since Sep 2020, any percentage of HQ requires a prescription in the United States and is not available over-the-counter. This ensures the medication is prescribed and sourced safely and in accordance with FDA regulations. Learn more here: https://www.aad.org/public/diseases/a-z/melasma-treatment#

Q: Why do I need to take breaks from using hydroquinone?

Q: Why is HQ banned in some countries?

A: In the past, hydroquinone products manufactured in other countries were found to contain mercury, which can lighten the skin but is highly toxic. Some countries banned the ingredient to prevent import/manufacturing of hydroquinone products that could potentially contain mercury. Mercury is illegal in the US. As long as the manufacturer of your hydroquinone products is reputable and based in the US (like ours), there isn't reason to worry about the possible addition of mercury.
