Since 2005, La Mer has worked with Oceana to promote ocean protection and restoration. La Mer has supported Oceana's Partners Award Gala, which honors outstanding work in the field of marine conservation.
In 2009, in celebration of the United Nations’ designation of June 8 as World Oceans Day, La Mer hosted nationwide retail events in late May in Washington, DC, New York, Los Angeles, and Orange County. Guests were treated to signature La Mer treatments and 15 percent of the proceeds went to Oceana.
In June 2008, Oceana and La Mer celebrated World Oceans Day in New York City. The luxury skincare company presented Oceana with a $100,000 donation to aid the organization's work to save the oceans.
