I've been using Beauty Blenders for a few years now and love them! I've tried foundation brushes but it left me super streaky and just looked awful. My Beauty Blender on the other hand doesn't leave ANY streaks and blends in my makeup perfectly.
I've found that it makes my foundations quite sheer, even my full coverage formulas. This does help create a somewhat natural finish though which is nice.
I tend to use the larger end of the blender for my whole face. It's such a soft sponge that it is still able to get into the creases around the nose etc and is definitely faster than using the smaller end in those areas.
I'd definitely repurchase, although I'm not certain how often it needs to be replaced!
i am so in love with my beauty blender,i wet it and squeeze the excess water out each morning to apply my primer then foundation,the dabbing up and down with it on my skin gives me a flawless finish.i use it instead of my flat top kabuki brush,i also use it when applying my concealer as the point on the beauty blender is great for under the eye area.you can also use it to apply setting powder,i love my beauty blender,you won;t be dissappointed
