The campaign by Ogilvy includes activity across TV, print and Facebook, as part of the global re-launch of the Hand & Body range.
The TV ad promotes the body lotions and uses the strapline "For skin so good, your body language shows it".
The campaign will run through key markets in Europe, with the core component of the digital activity featuring a bespoke Facebook application called The Body Language Tool.
The tool features six real women who use their bodies to spell out typed messages, which can be sent to friends, posted on Facebook and shared via various social media applications.
Michelle St Jacques, global brand director of Unilever, said: "This is an exciting new campaign for Dove.
"Women are spending more and more time on social media, which is why we decided to focus on Facebook creating engaging and playful applications they could share with their friends.
"It will enable us to bring Dove even closer to our consumers and give them an opportunity to have a live relationship with our brand."
The Facebook campaign also offers advice from body language expert Tonya Reiman at the 'Dove School of Body Language'. Further Facebook applications outline the new range and explains its benefits.
