This shape is perfect to reach every edge and contour of your face to prime, conceal, sculpt and highlight with any formula.
Comparing to the other 2 famous sponges including Original beauty blender and RT miracle complexion sponge, i have noticed that Sigma blender have smaller pores and to my surprise it is still as soft as them. The smaller pores mean that less product will be absorbed in the sponge and will not be wasted. As the sponges perform best when used wet, damp Sigma 3DHD blender doesn't dry quickly and you can get a lot of time while blending makeup. On the other hand the sponges with large pores become dry quickly and you have to damp them again.
The size of Sigma blender is smaller comparing to the other ones but it is easy to hold and i didn't got uncomfortable while bending my makeup. The flat sizes are perfect to apply under eye setting powder and baking which i can dust away with any large fluffy brush. The large round side and the smaller bottom side is very good for blending liquid, stick or mousse foundation. It provides flawless application with less product waste. Its unique shape help you to apply makeup in every nook and cranny of your face. The difficult parts like creases of your nose or area around eyes is difficult to be blended with flat or large round sponges while the edges of 3DHD blender help you to over come this issue.
It is easily washable with any mild shampoo but i love to wash it with Sigma SigMagic shampoo. It takes little longer to dry then other sponges because of large pores. It is less prone to breakage then other sponges but still i like to keep light hand while washing any sponge. It is recommended to change it every 3 months.
Overall i really loved this blender. It is reasonable comparing to Original beauty blender with similar performance and even better shape. RT sponge is less pricey but waste a lot of product and is prone to breakage due to its large pores.
Sigma Beauty 3DHD Blender is priced $21
