Is The Topical Skin Lightening Agent Hydroquinine Safe?
Topical hydroquinone has been used for over 50 years to lighten dark areas on the skin such as age spots and melasma. “In some senses, Hydroquinine has become a standard for treating acne scars, hyperpigmentation and dyspigmentation on the skin,” says Dr. Miriam Hanson, board certified dermatologist and cosmetic skin care expert in Austin, Texas. “Whether used alone or in combination with other lightening agents like retinoids, a steroid, Kojic acid – the so called Kligman formula, it is a highly effective agent for lightening and bleaching the skin.”
In 1982, the United States Food and Drug Administration(FDA) stated that creams that contain 1.5 to 2 percent hydroquinone were safe. However in 2006, the FDA reviewed all available data and decided that further studies are required on hydroquinone after researchers found that the product caused cancer in rats. Data also indicates that prolonged use of hydroquinone may lead to a condition known as ochronosis (a skin darkening disorder). Regardless of these observations, with its years of widespread use in the cosmetic and photography industries, there has never been a report of anyone developing cancer from hydroquinone.
Currently, the safety of hydroquinone is being evaluated by studies conducted by the National Toxicology Program (NTP) and researchers are working to answer the find out the safety of topical hydroquinone for skin.
