I really love this brush - so much so that I ever forsook my beloved Real Techniques Buffing Brush!
I have used this with liquid and cream foundation and it works brilliantly with both.
At first I thought it would be way too small and it would take me ages to do my whole face, but it blends my foundation so effortlessly that it looks perfectly natural and it doesn't take me any more time than usually.
The bristles are very dense, but flexible enough to be gentle to the skin and they are so soft! Blends everything beautifully, it really does all the work for you.
The handle looks odd but it fits in my hand perfectly and it makes the application easier because it rests very securely between my fingers.
Because it the brush is so dense it is, of course, a bit harder to clean, but that's the case with all dense brushes. After lots of uses and washes it hasn't shed a hair or bled.
If I ever lost this, I would definitely repurchase it :-) I bought it on a blogsale for $12, I think, but it's totally worth the original price ($16ish).

I don't really like this brush...it's soft, and the handle is awesome. But, I just don't. Although I've only ever tried it for foundation, maybe I'll give bronzer & blush I shot. I don't want to write it off just yet, just haven't found the best way to use it yet, or best products to use it with. continued >>

This is my favorite line of brushes hands down! This flat top synthetic in particular is my fave. I use it to buff and for blush and bronzer. I have had no shedding, or other negatives whatsoever compared to other MUAers. Have purchased Chanel, Lancome, Prescriptives, Benefit, Body Shop, Mac, and other brands of brushes and these Sonia Kashuk black handles are affordable and are long lasting. I have purchased the white handles and they are not as great as the individual black handles which are the higher end of her line. Only these! I also adore the ergonomic handle!

I like using this brush for bronzer (specifically, Bobbi Brown's shimmer brick). Traditional blush or powder brushes seemed too soft to pick up the shimmer brick makeup, but this brush is the perfect texture for it. It also is a good size for contouring with bronzer. It applies and buffs along the temples, cheeks and along the jawline very nicely. The flat shape allows great control of product placement and gives definition, but you can also buff and blend it out well. I have never tried using this for liquid foundation, but I did not like it for mineral powder foundation.

This brush is a great brush,don't get me wrong it blends foundation like a dream, but two problems...the brush I feel is a little too small for an all over foundation face brush, its perfect for cream blushes though, number two, its very cheaply made, I've bought cheap brushes from Walmart and elf that have lasted me linger than this brush has, after the second washing the glue completely gave out and no matter what I do to put the bristles back on the ferrule, it just doesn't function correctly like I would like it too... So I'm basically looking half retarded with just the bristles and no hankde when I do my foundation and powder....I'm getting the new sigma sigmsx brush, it basically the same price and none if my sigma brushes have eve came apart.

I use this brush to buff and blend my foundations into my skin. I don't use it to apply, since it tends to put on too much, but I use it after my foundation brush to get rid of streakiness my foundation may have and make the foundation look more natural. I absolutely adore this brush and it is a staple in my brush arsenal. The bristles are soft and really help blend my foundation into my skin so it doesn't look like it's sitting on top. I highly recommend this brush, it is definitely a must have.

I really don't remember why I bought this brush, except that I was buying a bunch of other brushes and figured "why not"! I can't find a good use for this brush. I originally used it to apply cream blush, but found that the bristles were a bit too dense and it was therefore hard to blend. After reading reviews on here, however, I would like to try using it to apply liquid foundation. It would seem that the brush is too small for that, but I shall give it a try.....

Dear Readers
This is a review to add to the many reviews that are already on this site.As always I never read any of the other reviews that others have written prior to my own personal review.This is something I do so that I may offer my readers an honest review.
It must be said that Sonia Kashuk is not readily available to me in my home country much to my dismay.I have been wanting this brush forever as well as her other brushes.
Luckily help is at hand and a Dear Friend by the name of Carin purchased a few of the brushes for me and sent them to me.I wanted to mention her good name as without her I would have suffered):
I am yet to pay her...but she trusts me,which is lovely.On to the review itself now.............
Firstly,this brush is aesthetically pleasing.This should not be the forefront however it is difficult to ignore it's beauty.It is very unique in its design and the handle twists,this allows you to hold the brush closer to the brush if you want a concentration of colour.You can hold the handle towards the end of the handle if you want a more softer and natural finish,therefore very versatile.The handle is black and when seen in person one can notice it's shine and shimmery dust swimming in the background.
The brush was cleansed prior to usage and it cleansed well with a small amount of baby shampoo.It was left on the edge so that it could dry.I noticed that it dried fairly quickly which was fantastic.Since I have had it I have used it consistently and with a range of different mediums,one being foundation.I applied with a traditional paddle foundation brush,and then went over with the Sonia Kashuk Flat Top,it worked the foundation in to my skin,with ease.
I buffed a little(not too much) as I have dry skin and I must be careful that I do not perform an exfoliating exercise.
The finish was "flawless" sounds like an advertisement does it not?This brush does not require an advertisement as the results speak for themselves.ergonomically
The second medium I used was a loose powder over the top of my liquid foundation,just to set it.I use powder very sparingly and lightly.I adopt a pressing and pushing action rather than wiping as the foundation could be disturbed potentially underneath.We do not want that,after our fantastic finish,):
After which I just use a fan brush just to knock off any excess that is there(if there is)usually the pressing action is the' icing on the 'cake.
The third medium is cream blush and liquid blush.If I am using any of these products then they are applied straight over my foundation prior to any powder.The mediums buff in to the skin with ease,and it looks as though the colour is part of my skin(some people refer to it as a lit from within look.However I am very pleased with the result.
If any of you have dry skin it is beneficial to not undertake concentrated buffing,this action as stated previously tends to exfoliate your skin.
I commenced using cream blushes a few years ago when my dry skin had reached it's height.One reason for the switch is because I generally suffer with dry skin,the other reason is that I had to have some long term medication,which in turn plays havoc with my skin.
Summer's are sometimes difficult as the medication makes me have 'flushes' and skin becomes a bit damp.I then have to lightly blot as this is artificial.I purchased some products last year,which can potentially calm the skin down,I will hopefully use them in the months to come.At times I have to use products that are used on television where there is increased lighting which makes models quite hot and flushed.
I would not use such heavy duty products daily,but they are great to have,in case I need to be somewhere where I do not want people to concern themselves with.
The next medium I have used it for is with a contouring product,and I tend to use a slightly darker foundation for this particular look.I t works well with a light buff.I tend to use a light hand when doing this,as it can look horribly wrong.Contouring should be light and natural during the day,and can go heavier for the evening.Contouring can make or break a look,and practice is paramount.You should also know what you are doing especially if using foundation to add depth to your face..
The colour should diffuse lightly right underneath your cheek bones.There are many contouring powders on the market now,and Sleek products launched a powder some months ago.Sleek is one of the first drug store companies that came out with a product of this kind.
If any of you are familiar with ELF flat top powder brush will know about the size ratio.The Sonia Kashuk brush head is much smaller(just for size reference).It has a good weight and is ergonomically designed.
I do not have anything negative to say about this wonder brush except it is wonderful.If you purchase this and are any thing like me you will require a back up brush,so that you can keep one for foundation and the other for cream and liquid blush.Cream blushes are very highly pigmented and it is wise to have a separate just for foundation.I can guarantee that you will adore this brush,which is why I am saying you will need a backup brush.In fact,I need to build on the whole set of these brushes.I will write to Santa early and hope for the best.
This review is in honour to my Dear friend Carin,who is so so far away but will do any thing for me.Carin,also sent me some products through the post and they are lovely,I feel her warmth,calmness and empathy through the words she writes to me often(very heartfelt)so Thank You to a beautiful person from so far away.A warm Thank you to all my readers.
Regards

This brush is awesome!! So soft and buffs liquid foundations in like a charm! It is worth every penny and is very affordable compared to sigma or mac brushes, I bought mine for around $14. GO GET THIS BRUSH!! LOL

The one on display at target was so soft, so I decided to buy it.
I was looking for a backup foundation brush and liked the shape of this one.
The quality is very much lacking.
It's quite stiff and mildly scratchy, my face becomes irritated while applying the foundation. It doesn't make my foundation look bad or anything but it's too uncomfortable to really use.
I've washed it a few times to no avail - the stiffness remains.
The harshness of this brush makes it seemingly impossible to use for other purposes.
I still keep it because it's kinda costly for a drugstore brush and for the rare times I'd need a backup.
Pass if you're thinking about it..

I've used this brush every day for over 2 weeks and I absolutely love it. I use it for liquid foundation; I apply a few dots of foundation on my face and then I use this brush to blend it out. The brush is really soft but dense enough to evenly apply foundation with. I haven't experienced any shedding even though I've washed the brush twice now. It's the only foundation brush I own/use so I don't have anything to compare it to, but over-all I'm really happy with it.

I use this brush over my Sigma ones EVERY DAY.
Easily my favorite brush I own.

This brush is absolutely great! I use it to put on cream foundation and do a swipe in the pot and then circular buffing motions to apply, gives great even coverage. Money well spent and would continue to buy if it ever needed replacing.

I am so dissapointed. I really wanted this brush to work, especially given all these glowing reviews. I like the size, since my petite face favors small brushes. The density and application were great at first too. UNTIL it came time to wash it. I use a very diluted amount of Dr.Bronner's soap for all of my brushes and take great care to ensure that the ferrules don't get wet. I lay them flat to dry, never standing. Even with all these precautions, this brush shed NASTY STYLE. It lost so much of its density already :(. I thought I might have just received a dud, but after checking out some more reviews hidden under the raves, it shows that I'm not the only one experiencing shedding problems :(. The ELF $3 Studio Powder Brush is a 5th of the price and A MILLION times better.

AMAZZZING brush for blending liquid foundation.. gives an airbrush look and feel... i love it.. easy to wash... and drys quick. I haven't had it shed on me and I've been using it for 9 months now. The only flaw was... the handle came off.. but with some super glue its as good as new! why i knocked off 1 off the packaging quality.

I love this brush. I've used it with liquid foundation, powder, and cream blush. I love it. Its a little small for stippling on liquid foundation, but its perfect for buffing out/diffusing cream blush. Its really soft, the packaging is beautiful, and the bristles don't fall out. <3 it. I would definitely buy it again, except that I don't think I would ever need to lol because its so great. But I would definitely recommend it, especially for the price! continued >>

I have had my Flat Top for over a year and I have to say after many cleanings and lots of use it has shed once and is still in great condition. Granted this is a thick brush and with that in mind it is perfect for buffing to give a flawless look. I use this with creams and liquid foundation. But it works best with creams. It does take a long time to dry after cleaning but its worth the wait. I did have issues with the handle coming off in the beginning but with a little super glue I haven't had any problems since.

This brush is definitely the most useful makeup brush that I own. I used it with my liquid foundation, pressed powder, concealer, bronzer, powder blush and cream blush. It does an amazing job applying all of these products.
I also noticed it's a lot softer than the Philosophy multi-purpose brush and it definitely applys nicer as well.

Did not work well with BB cream. It is really soft when dry but it soaked up too much product and did not glide smoothly on my face. The SK duo fibre brush (large), which I love for my Nars powder blushes, worked better with BB cream. Agree with the other reviewer about there being quite a bit of space between bristles and barrel. In fact, the whole thing popped out while I was washing. Back to Target it went.

I love this brush so much. I used to buff out my blushes and bronzer as well as apply mineral makeup. This brush is super dense and very soft. The handle has an easy grip ship and it comfortable to hold. This brush blends really well, obviously it will work differently depending on your brushes strokes and how hard you press- but for me it glides my makeup around my skin extremely well. It disperses the color evenly and leaves a nice finish. I've had it for over a month and have washed it 6 times since I bought it and have noticed little to no shedding and no brush deterioration.
