To say I've never tried Sigma Brushes before, I'm ashamed of myself. I've here such amazing things about the, but just haven't got around to trying them! I think my first one, is one of the most talked about brush from their collection the Sigma Flat Top Kabuki Brush F80. The brushes are made with Sigmax Synthetic Bristles, ad I have to say that this brush is possibly the soft brush I've ever had on my face! It feels so good, that I found myself running it back and forth over my had when I got first held it. The flat top Kabuki brush from Sigma is designed for the application of liquid or cream cosmetics, to the flat areas of the face such as the cheeks and forehead. I have seen a lot of people suggest using flat top brushes for applying foundation, so I tried it out on this brush - with my initial first use. I applied foundation onto my hand and ran the brush over it, I then used a circular motion to apply it to my face. It buffed into my skin like a dream! It left such a flawless finish on my face, and because the bristles were so soft it left my skin feeling soft.I have to say I am now reaching for this to apply my foundation, over my Real Techniques essential foundation brush, as the finish is so flawless.You pick up the amazing Sigma Flat Top Kabuki Brush F80* from Beauty Chamber for £15.75.
