What do I need to know about starting lustra (hydroquinone)?

Hydroquinone. Lustra is a type of topical skin bleaching agent that contains hydroquinone. Hydroquinone has been used for years to bleach out darks spots on the skin (usually the face). Some people are voicing concern that hydroquinone may have long-term safety issues. Therefore, the use of hydroquinone for skin bleaching has been used less and less over the past couple years.
