A new Pinterest feature will allow users to virtually try on products, starting with lipstick, before they shop from retailers like Estée Lauder, Sephora, bareMinerals, Neutrogena, NYX Professional Makeup, YSL Beauté, Lancôme, and Urban Decay from L’Oréal. To use the new feature, pinners will first open Pinterest’s smart camera, “Lens,” while in Search, then click “Try it” to explore the different lipstick shades available. To shop the products, you just swipe up.

Another way to access Try on is by typing in lipstick-related terms into Pinterest’s search engine — like “plum lipstick” or “red lips,” for example.
