The NYX Marshmellow Prep + Set Duo is a 2-piece makeup kit featuring a smoothing primer and matte setting spray that work together to create long-lasting, flawless makeup. The Marshmellow Smoothing Primer is a 10-in-1 multitasking makeup primer with plumping properties that smooths skin, grips makeup for better application, and helps conceal pores. The Marshmellow Matte Setting Spray provides up to 16 hours of makeup wear with a soft matte finish.
The primer applies with a light, fluffy texture and can be worn alone or layered under foundation and concealer. The setting spray should be shaken before use and misted about 6 inches from the face for optimal results. Both products feature a pleasant marshmallow scent and are formulated to be vegan and cruelty-free. This duo is ideal for prep and set routines, offering smooth makeup application and extended wear throughout the day.
