Product Description: Pro is the perfect application method for darker-toned products that would be difficult to rinse clean from a lighter colored applicator. Use with complexion products, long-wear makeup and self-tanners for flawless results. beautyblender features an open cell structure that fills with small amounts of water when wet. This allows the sponge to be “full” so that the makeup product sits on top of the sponge rather than being absorbed, allowing you to use less product every time. When wet, beautyblender doubles in size and becomes even softer, returning to its original size when it air dries.
