Are Skin-Lightening Moisturizers Safe?
Using skin-lightening moisturizers to erase hyperpigmentation can come with its fair share of health risks. These risks are due mainly to the potent ingredients in skin-lightening products.
Hydroquinone, the main ingredient in most skin-lightening moisturizers, may lead to cancer as well as ochronosis, which further darkens the skin and causes joint problems [source: Merola]. In many Asian and European countries, hydroquinone has been banned from over-the-counter products. In the United States, however, manufacturers are allowed to use the ingredient, as long as it makes up only 2 percent or less of a formula.
Physicians may prescribe a skin-lightening moisturizer with up to 4 percent hydroquinone. But this may not be a healthy prescription. In 2006, the FDA proposed a ban of skin-lightening products that contain hydroquinone. They are currently reviewing research, data and public comments on the proposal [source: Bouchez]. While some physicians agree that hydroquinone is dangerous, others argue that the ingredient is highly effective and acceptable to use [source: Janes].
In rare cases, mercury salts are also incorporated into the skin-lightening formulas, but use of products containing mercury is not often recommended. Though it can stop melanin production, mercury is also a toxic substance [source: Oakley]. Once a common ingredient in a number of products, mercury has been removed from most cosmetics over the years and is still strictly regulated. Exposure to mercury can lead to neurological complications and kidney damage [source: MedicineNet].
If you intend to use a skin-lightening product, check the ingredient list. A skin lightener with mercury or a high concentration of hydroquinone could be unsafe. A good replacement formula might contain kojic acid or a combination of retinol and botanicals [source: Janes]. If you have concerns about a particular formula or your skin condition, contact your physician for advice.
