Do I love them? Yes. Do they do anything for me? Yeah! In so many ways...
Setting sprays have different purposes', that’s kinda why I own so many of them. Oh man and I do want more.. So what are setting sprays you ask? Simple: to set makeup, help stray away from that "powder-y" look, make shimmer eye shadows look more intense, and to hydrate your face.
There are a lot of different types for different skin, my favorites are the ones designed for oily skin, like Urban Decay's De-slick, Skindinavia's No More Shine, and Skindinavia's Bridal finishing spray. This type of spray really helps keep your makeup looking fresh all day with a semi matte finish. The Urban Decay All Nighter setting spray is awesome for all types of skin, weather your normal, oily, or dry; makes your makeup last all day! I use Mac's Fix + to hydrate my skin before putting on makeup, spray on my shadow brush to make eye shadows or pigments more intense, and to hydrate my skin throughout the day when its dry. I also love the smell of it.
Now, more of a skin care type of facial spray is the Rosewater spray from Mario Badescu. I literally drench my skin in this stuff after I get out of the shower or right before bed. It hydrates my skin so nicely and evenly. I cannot skip a day of this stuff! My favorite spray by far, and has an amazing rose aroma.
I'd recommend trying one if you have problems making your makeup last throughout the day. Also if you have dry skin or want to make your skin look more dewy. Facial sprays are an awesome treat to your face after all your makeup is done, feels amazing!
