1 of the top 6 ingredients in YSL Beauty's formula also appear in Maybelline's, so treat this as supporting evidence rather than proof of an identical formula.
YSL Beauty and Maybelline 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, Maybelline's SuperStay Vinyl Ink Liquid Lipcolor shares 5% of its top ingredients with YSL Beauty's Vinyl Cream Lip Stain, at roughly $13 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.
How matching works: We match products by publicly documented parent company ownership. Ingredient overlap is shown alongside each match as supporting context, so you can judge formula similarity for yourself.
