Myth #1: Hydroquinone bleaches your skin
Hydroquinone does not bleach your skin. Your skin color is determined primarily by a pigmentation called melanin. The more melanin, the tanner your skin appears. Hydroquinone works by decreasing the production and increasing the breakdown of melanin pigment granules in the skin's pigment cells, causing your skin to appear lighter. Hydroquinone, therefore, does not bleach or peel off your skin in order to reveal fairer skin.
Myth #2: Hydroquinone is harmful
Some people think that there are negative side effects of hydroquinone because of the misconceptions about the product. Research has shown that unwanted side effects are generally rare or minor.
Myth #3: Hydroquinone is carcinogenic
This myth came about from a study that injected large amounts of hydroquinone into rats. However, abundant research on the human use of hydroquinone has shown that it is both safe and effective, with 2% hydroquinone as the most effective concentration for over-the-counter use. Additionally, hydroquinone is an antioxidant and some research has actually shown that workers who handle pure hydroquinone have lower incidences of cancer than the general population.
