I have very mixed feelings about the 188. On the one hand, it's my favorite brush for highlighting. On the other, most of my highlighters are easily applied with my fingers (my favorite is MAC's Luna Cream Colour Base), so a brush isn't really necessary. It is a very well-constructed brush, I've had minimal shedding and it's very good at blending and giving an airbrushed look. Was it worth the money I paid for the uses I have for it? Probably not. Is it a great brush? Definitely. I think if you use powder-based highlighters this is definitely a good buy, otherwise I think the 187 has a lot more bang for your buck.
I really didn't like this brush at first. However, I've grown to really like it and use it all the time! I use it to apply blush mainly, but you can use it for a lot more - foundation, highlight, powder etc...I love using this for blush because it allows me to build up and places the perfect amount of colour on my cheeks. Blends very nicely too, and never sheds!
This brush is a multitasker.
Use can use it for foundation, highlight or blush.
I've tried it for all of those things....
I'd rather use a Sephora #55 for liquid foundation-
But this little wonder is amazing for heavily pigmented blushes.
It's small so you can place color exactly where you want it on your cheeks and it blends really nicely.
The Duo Fiber can help you avoid turning into a discoball with heavily glittered blushes.
I use this brush all the time with my Nars Luster blush...
when I'm done with putting color on my cheeks - I use the same brush to pop a bit of my blush color into my crease - it really ties the look together.
great lil brush, magical wonder, i love my 188, i have two 187's one i use for liquid the other for powder. i wasnt sure if i needed the 188 but the reviews it has been getting pushed me to purchase it.
i used it this morning for my tinted moisturiser, where i would usually use my 187... it was a great finish, i cant say its BETTER but for sure you feel like your paying attention to every nick and cranny.
... i have now found that this little brush is great for under eye concealer... i apply concealer under and around my eye using a concealer brush....and blend away with the 187 brush... its magical!!!!
i say yes yes yes to this brush for concealer application.
The #188 is definately a brush staple it's Very versatile, like most MAC brushes. This brush is great application brush for applying everything: powder, liquid foundation, bronzer, powder and creme blush....It picks up up color really well plus, it allows you to build product as needed. I washed it several times and it hasn't shed which is great.(I hate excessive shedding) I use the 188 so much that I bought another as a back up. I would definately buy this again.
Cons: A little costly
Great little brush for mineralized blushes. It's small enough to fit onto the apples of your cheeks and the white bristles makes it easier to blend out the mineralized product. If used for foundation it is even better because it's small enough to get into the trickiest spots on your fast, like the side of your nose.
I have both 187 and 188. I love both of them but I think I like 188 better since it is smaller and gives you a more precise application. This is a must have brush, I will definetely get 1 or 2 more 188s to use for different purposes. This baby applies the products well, almost airbrushed, you dont get that layered made up look at all, and the products just blend beautifully with your skin. You have to get some tutoring on how to use the brush though, ask a MAC assistant or watch it on youtube. If you have a heavy hand the results won't be good at all. Technique ladies, is extremely important with any brush, and especially with this one.

Hmmm, it sheds once in a while.. One lippie of for that. But still good brush.
I absolutely love this brush! I will never apply liquid foundation with my fingers again. It really creates a soft, airbrushed look without using a lot of foundation. Yes, it is expensive but will last you a long time if you take care of the brush with regular cleaning. Love it!
edit: although this does work well for liquid foundation, i recently bought the 109 brush from MAC and love that muchh more!
I politely disagree with those who said that this brush is versatile, or it is good for creams....It is NOT. It is only good for powder blushes, because it packs on very lightly. That's about it.
