Usage Instructions To replace the refill push the original refill pan out through the pinhole in the bottom of the case. Dampen the Beauty Cake Sponge in water or with the Balancing Gel Mist until well hydrated. Pick up the foundation with the sponge in a firm circular motion. Gently buff evenly over the face until the desired coverage is reached. Using a damper sponge will give a lighter sheerer coverage.
