The beauty brand has long supported cancer-fighting causes, raising more than $75 million (£46 million) through fundraising efforts such as its annual Entertainment Industry Foundation Revlon Run/Walk for Women, reports People.
"These lips can flirt, laugh, turn heads. These lips can save lives by talking to all the women you love about cancer, encouraging them to talk to their doctors about early screenings, asking them everyday until they go, because with cancer the sooner you detect it the greater your chance of survival. Save a life with your lips. Talk about cancer today," Berry and Stone say in the PSA.
Stone also has appeared in a print ad with her mother, a breast cancer survivor.
Earlier this month, American Idol alum Kellie Pickler shaved her head in support of her best friend, who is undergoing chemotherapy after getting a double mastectomy due to breast cancer.
Writer Judy Blume recently opened up about her diagnosis with breast cancer, and 64-year-old actress Kathy Bates revealed that she had a double mastectomy after she was diagnosed with breast cancer several weeks ago.
