Sonia G Fan Pro is a brush.
Sonia G Fan Pro Brush ($TBA) is a small, goat-haired fan brush that has a rounded, pinched ferrule where the brushes flare outward to create a gently curved edge. It is incredibly soft and moves fluidly against the skin--no feeling of any individual bristles at all.
The brand recommends the original Sculpt Three (as the Fan Pro is based on) for those who want more intense application, greater product pick up, as the Fan Pro is airier and has a bit more give and spring, so it'll lend itself more to a buildable application. The brush is thick enough that I feel like it picks up enough product and has enough bristles there to diffuse and gently blend it into the skin, rather than just deliver a harsher line of product. It's small enough to work well underneath the eyes for setting powder or to highlight cheek bones or work along the temples. If you tend to like and use fan brushes, it's one of the more universal brushes in the set.
The Fan Pro is based on the best-selling Sculpt Three, similar size and shape, goat Saikoho bristles too, but here they are not dyed which means we can safely use it with creams. It works so well with both powders and solid creams, I often use it with highlighters that come in a stick packaging or with pans that have a more solid or sticky type of finish, there are some fun hybrid formulas around and this little fan can handle them so beautifully, if you pick the product with this Fan Pro and then sweep onto the skin, the glow equals glass skin and it won't disturb the underneath application, it's absolutely gorgeous.
