Hi-Def Matting Spray was formulated specifically for use in HD cameras as a means of sealing makeup without it being detectable or reflective under lights, and especially in camera. This water-based hybrid formula will matte down any skin texture glare or shine, and remain undetected, even under the harsh close-up lens of an HD camera. When sprayed very lightly it forms a film membrane that is completely matte to the natural eye and camera lens. It can also be very lightly sponged or brushed on by hand for greater control in application. It's the perfect makeup fixative wherever you need a makeup setting agent that will be truly matte on skin or hair, and not create any kind of sheen or noticeable texture. Use it to increase the daily wear of any kind of makeup, temporary tattoos-and it's great to use on hair, brows, and facial hair too when you need to set or protect makeup! IMPORTANT NOTE: This is a professional use product, and because this product contains matting agents, you must shake it thoroughly first before using. It is strongly suggested that you stop and shake it well during use as to keep the ingredients thoroughly mixed to eliminate irregular spraying issues or clogging. It is recommended that you wipe the nozzle area clean with alcohol after using and before storing to prevent a clogged sprayer. Ingredients: Deionized water, Acrylate Copolymer, SD-40, Silica Dimethyl Silylate.
