The webcast will be held on 27 September at 7pm GMT. Listeners can post questions to the Dove team.
Unilever has been hugely successful with its Dove campaign, which focuses on the virtues of 'real' women rather than models.
PRWeek is bringing PR and ad teams together in a forum to learn more about the campaign's strategy.
Participants include Unilever senior marketing and communications manager Stacie Bright, Edelman general manager of consumer brands Lisa Sepulveda and Ogilvy & Mather creative director Maureen Shirreff.
