Sonia G Cheek Pro is a brush.
Sonia G Cheek Pro Brush ($TBA) is a small, very dense cheek brush that flares out slightly from the ferrule and has gently rounded edges and comes to a domed edge where the left and right sides are noticeably curved but the edge is fairly straight. The brush is intended to splay out a bit after subsequent use and washes, so it will be more small-to-medium (not quite a medium-sized, typical blush brush but not a tiny cheek brush either). The size of the brush was also intended to make it so it could be used in smaller product pans, too, which is definitely accurate.
Like the other brushes by the brand, the bristles are smooth, soft, and silky with the bristles moving together as one and feeling very smooth as the brush is patted, swept, or buffed against skin. I see this brush being the most versatile and useful brushes in the set, but it will be particularly good for those who prefer more intense application of product (more payoff with less work) or who have firmer, denser, or stiffer powder products in their arsenal. It is also nice to use to pat color onto the apples of the cheek and then using sweeping motions to pull and disperse the color to blend out. I liked it for more concentrated highlighting or when working with a more dense highlighter (like gel-powder hybrids).
It's notably denser than other tried and true favorites that have a similar shape and size (Chikuhodo Z4, SUQQU Cheek Brush); much more of a "solid" brush in that sense without the airiness of squirrel hair options that exist but much smaller than more traditional blush brushes like Wayne Goss 11. It puts me in mind of Hakuhodo's B505 a bit more, just far, far smaller and less flat in overall shape--but similar in purpose.
This is one I could see myself getting a second of, though I am pretty partial to Sonia G. Face Two for a denser blush brush (and that's one I bought a second one of!).
This little Cheek Pro brush is at the same time super cute and truly efficient! It works with any type of finish, matte, sparkly, gelee, frosts, hybrids gel/powder formulas, if you usually cannot get any color pay off, this one will definitely work wonders! The bristles are quite short and quite dense as you see in the comparison pics, they will facilitate the work on smallest pans, post wash they splay out nicely to a paddle pom pom shape and deliver a diffused application on the cheeks.
