I normally don’t use a brush for my foundation, therefore I don’t like this product to well. Also it is very hard to clean

I'm not sure what a "face curve" brush is but I do use this brush a lot. Mine doesn't look like the one pictured though... It's slightly rounded but not to that extreme. I find this brush is best to use for contouring or applying bronzer for a more dramatic look. I would give it 5 stars but the top fell off so I had to super glue it back together. Booo

is really beautiful, its fibers make the foundation of makeup look perfect on the skin
