To use the Total Face Sponge Duo, begin by dampening the sponge with water and squeezing out any excess moisture. Next, take your preferred liquid or cream foundation and apply it to the rounded side of the sponge. Using gentle dabbing or stippling motions, blend the foundation onto your face for a flawless finish. The sponge's unique shape allows for easy access to all areas of your face, ensuring even coverage. For precise application of concealer or for reaching difficult corners and contours, make use of the precision tip of the sponge. To maintain hygiene and prolong the sponge's lifespan, it is recommended to clean it regularly with mild soap and water.
