This study focuses on the recent increase in the use of older celebrities in cosmetics advertising. It asks what kinds of ideas and values these images may attribute to discourses of ageing. Drawing on a Multimodal Critical Discourse Analysis (MCDA) perspective, this study focuses on L'Oréal UK and Ireland Web advertisements, examining how these advertisements use older celebrities to redefine/reposition ageing and exploring how they relate to the notion of ‘successful ageing’. In these advertisements, using cosmetics is presented as a positive, empowering choice. The advertisements simultaneously promote new discourses about ageing in which older women's sexuality is presented as a form of power. However, the analysis shows that the underlying discourse pathologises ageing and presents ageing as something which can be evaded through the consumption of cosmetics. It thus turns ageing into a choice, but one where the ‘right choice’ aligns with neo-liberal ideas about ageing well. For women, decision-making about ageing seems to be a never-ending process that requires constant construction, promoted through the older celebrity's sexualisation. Women are expected to always look good and present the best versions of themselves, even at the latest stages of life, which reproduces and legitimises sexist and ageist expectations about women's appearances, including the expectations that for older women to remain visible and attractive, they must hide outward signs of ageing.
