This is my favourite brush to apply foundation, it gives an airbrushed look.
However, I only use this to apply liquid foundations. Its best for applying quite runny foundations. For cream, powder or any thicker foundations - this is not the brush.
I love this brush from Real Techniques for when I want a slightly more full coverage look to my foundation (I often use a beauty sponge or fingers to apply). The density of the brush gets the product on really well, and blends it out evenly without streaks. Whilst it seems some think it is too small, I find the smaller size and shape of the brush works well for really getting the product everywhere around the face (eg, around the nose etc.) Would recommend if you are looking for an effective and long-lasting foundation brush.
This is a wonderful, affordable beauty sponge. Whilst I haven't ever tried the original beauty blender as I could never justify the price, I don't feel the need to with the results this sponge provides. I use it damp for application of foundation, and as someone who loves natural looking makeup, I love the second skin, natural, blended look that this sponge gives. I haven't had problems with longevity as some other reviewers have, and find that it washes really well with makeup sponge cleanser (I just use the one from Daiso that works a treat). Would definitely recommend.
