The principle for using these is the same as with the Beauty Blender - you need to dampen them, they expand in size and then you work liquid and cream make-up products into the skin by using a bouncing motion. The pointed end is used to apply foundation or concealer around the nose or eyes.

Initially I only purchased one sponge, just out of curiosity and to do a trial run, but after using it only once I knew that I needed more. These are incredibly easy to use and apply liquid and cream foundations like a dream, leaving you with a truly (yes I'll throw in the cliche) flawless finish!
I wholeheartedly recommend these. This might sound dramatic but they will transform the way in which you apply your foundation, helping you achieve a truly natural and well blended finish.
If you've tried the Beauty Blender as well as these then please leave a comment below and let me know how they compare.
