Skin lightening products -- also known as bleaching creams, whiteners, skin brighteners, or fading creams -- work by reducing a pigment called melanin in the skin. Most people who use lighteners do so to treat skin problems such as freckles, age spots, acne scars, or discoloration related to hormones.

March 24, 2014 marks the 25th anniversary of one of the worst environmental disasters in U.S. history. The Exxon Valdez oil spill began when a 987-foot-long oil tanker ran aground on a reef in Prince William Sound, Alaska. The spill stood as the worst in U.S. history until BP's Deepwater Horizon spill in the Gulf of Mexico in 2010. The Exxon Valdez released an estimated 10.8 million gallons of crude oil before the spill was contained, fouling about 1,300 miles of coastline. The remote location of the spill and a delayed and inadequate response from Exxon and Trans-Alaska Pipeline operator Alyeska made matters even worse.
