MullenLowe UK has partnered with Unilever's Persil and Arsenal F.C. to launch a campaign addressing the stigma around period stains in sports. The campaign, titled 'Every Stain is a Part of the Game', features football stars like Beth Mead and Katie McCabe.

The campaign aims to challenge the double standards in athletic culture, where blood from injuries is often celebrated while period stains are shamed. The campaign encourages young girls to embrace their bodies and participate in sports without fear or embarrassment. By highlighting the importance of viewing every stain as a badge of honour, it fosters confidence and resilience among female athletes and promotes a more inclusive environment in sports where all marks are accepted and celebrated.
