YSL Beauty Rouge Pur Couture Vernis À Lèvres vs L'Oréal Paris Brilliant Signature Shiny Lip Stain

Both made by L'Oréal Groupe. Here's how the ingredients actually compare.

YSL Beauty and L'Oréal Paris are both owned by L'Oréal Groupe. When two brands share a parent company, they sometimes develop products with overlapping ingredients, though not always identical formulas. In this case, L'Oréal Paris's Brilliant Signature Shiny Lip Stain shares 97% of its top ingredients with YSL Beauty's Rouge Pur Couture Vernis À Lèvres, at roughly $12 compared to $45. Whether that overlap is enough to make the switch is up to you — this page exists so you can judge the actual formula for yourself instead of guessing.
