When I first heard about this product I was surprised (in a very good way)! I love my Clarisonic but I never thought of them coming out with such an innovative product like this. If you don’t know what it is, Clarisonic is typically an electric face washing brush. It has interchangeable heads to do different things, but this make-up brush attachment is a game changer. Make-up by Mario helped launch this product so I knew it had to be good. I told my sister and she bought it and raved about it. I was thinking “I’m sure it’s super cool but is it really necessary? Probably not.” She ended up buying one for me because she wanted someone else could experience the joy this product brought. I genuinely thought she was being a weirdo. Well, she wasn’t. I don’t even know how to explain how amazing the sonic foundation brush is. I was shocked and confused as to how it works so beautifully until I researched. The brush uses a patented oscillation technology which allows it to generate 18,000 micro-blends per minute. It blends ANYTHING into your face flawlessly (concealer, foundation, color corrector). Using it required no effort or man power! You turn it on and let it work its magic while you just lightly move it around your face. The sonic head was mind blowingly quick, their claim is 60 seconds or less (its no joke). In reality this brush can replace so many others that you would usually use while applying make-up. I really cannot say enough good things about it, but I will say one more. It’s inexpensive for such a high quality product and I will definitely be buying more of them. MUAH MUAH MUAH from me.
