Rated 5 out of 5 by from The best for a reason! I've used many buffing brushes for foundation, including other Sigma brushes that performed well, but not as well as my favorite big-name blending sponge. I finally decided to pay full price and buy this brush about 2 months ago, thinking it would be good, but similar to other brushes. I couldn't have been more wrong. This brush gives my foundation the most beautiful and skin,-like finish I've ever seen! My face looks flawless and my foundation goes further than ever before. This brush doesn't absorb the makeup at all...a phenomenon I can't explain when all my other brushes will at least absorb some. And so base is done in the blink of an eye. I cannot recommend this brush enough. Worth every penny.

Rated 5 out of 5 by from Perfection! I bought this brush 2 years ago and it is in excellent condition. I've washed it multiple times with a mild soap and has remained soft. It makes my face look flawless. Do not hesitate to buy.

Rated 5 out of 5 by from LOVELOVELOVE My boyfriend got me this brush along with many others and I just love it so much! I tend to have trouble finding the perfect tool to apply foundation and blend on my skin. I have very textured skin and a beauty blender doesn't quite do the job as good as this flat Kabuki! So since receiving this gift, I've been very satisfied with the look of my skin after applying foundation. I would definitely recommend this brush!

Rated 5 out of 5 by from The best I bought foundation brushes with others companies and it didn't give me the WOW, so I turn back to the sponges, but every time I see this brush I was a little skeptical but then I already bought few brushes form Sigma and the quality was there so I finally bought it. And yes it give the WOW factor that I was looking, very easy to work with (at least my hand didn't get tired), is big enough (something the other brushes lacked), easy to clean. I would recommend it.

Rated 4 out of 5 by from Easy to use = hard to clean The brush is definitely worth the hype. Perfect for applying cushion compacts (in tapping motion) and blending all sorts of cream/liquid primers and foundation by buffing. I think it is too big and round for the under eyes but it can blend concealer in really quickly. Comparing to my RT orange sponge, the coverage is higher and the finish is more matte and poreless (I buffed). However, I find it hard to clean and it takes really long to dry. I have tested F80 out with my liquid foundation and promptly cleaned it right after. It still took a lot of rounds of washing with the mat before the brush is completely clean. 2 rounds with a weak cleansing oil bare made a difference. 2-3 rounds with my cleansing balm (which removes even the Heroine Make Mascara easily) and warm water removes only a little of the gunk About 2 rounds with my bar of soap (Goat's milk handmade soap...I think any soap you use will do the trick as long as it is not too drying): I lathered it by circling on the soap surface before doing it on the mat. The brush is finally clean! All my other brushes were thankfully not as high maintenance. It is an unavoidable inconvenience for the high performance, I guess?

Is this brush work well for pressed powder foundation? I'll be using it with bare minerals bare pro powder foundation.

Asked by: Leibaby
The F80 brush works great with powder foundations! However, the most effective brush for powder foundations is our F82 brush. The curved brush head on the F82 allows you to buff powder foundation into the skin quickly and seamlessly.

Would this brush work well for someone with acne? Would it still work to cover?  I’ve never used a brush for foundation always just use a sponge but I want to try something different.

Asked by: April26
This brush provides seamless, medium - full coverage and works very well to cover acne! For extra coverage, we also recommend the F64 - Soft Blend Concealer brush!

It's very practical to put on makeup, there are only two versions, I feel doubtful, what is the difference

Asked by: WENHUI
Thank you for your question. The two Sigma logos you see on our current collection are both official Sigma logos. Any product is guaranteed authentic if purchasing directly from The curvy letters are our old logo, and the sleek new font that incorporates the Greek symbol 'Sigma' is our new logo. We are currently still transitioning into the new logo brushes.

Theres the F80 AIR FLAT KABUKI and this, the F80 Flat Kabuki, the 1st says it was inspired by this, but if its not identical, whyd you let it be called the F80? And in what ways is it different? The Bristles? Weight? Handle? Density? And Which is better?

Asked by: Elle909
The F80- Air Flat Kabuki is the classic F80-Flat Kabuki re-imagined! They are both fairly dense kabuki brushes with the same size handle and similar brush heads. However the F80- Air includes Duo-Fibre bristles as well as Sigmatech bristles. These Duo-Fibre bristles provide a more natural and dewy finish, and specialize in applying liquid foundations. The classic F80- Flat Kabuki is made with Sigmax fibers, that are extra soft and can be used with both liquid and powder products. The increased density on the F80- Flat Kabuki also provide fuller, more matte coverage. Depending on which finish you like, either could be the option for you! Natural, lighter and dewy coverage= F80 Air. Full-medium coverage = F80- Flat Kabuki.

Does anyone else use this brush with Lancome Teint Idole foundation have a hard time cleaning? I've noticed that the foundation balls up and sinks to the base of the brush when trying to clean. I have to really open up the fibers to get the gunk out.

Asked by: Mollie
Unfortunately we do not personally have experience with this foundation. However, I recommend the Sigmagic Scrub to clean extra dirty brushes, as the rubber fingers assist in getting the product deep into the bristles!

What makes this different from other flat top buffers? I have SOO many but I hear this is so great.. What makes this brush so special?

Asked by: Leona
I honestly can't tell you product-specific why it does, but all I know is it does! I haven't used it on very thin foundations, moisturizers, CC creams it cosmetics your skin but better, which is a pretty thick foundation, and all I know is I wish I would have found this a long time ago because this is amazing

I have been having major issues with the fibers in my brush coming out and landing onto my face when applying foundation. Despite cleaning and caring for it well, the hair fibers keep coming out of my F80 brush. Need help!

Asked by: Natasha
