As i grew more with doing my makeup daily i just used a primer as went on my way. Finishing spray are becoming more popular in the makeup world just to set your makeup for the entire day, well here is my experience after trying them. I'm more of a huge fan of primer and being that i have combination skin i can't use every product but i decided to give finishing sprays a chance. L.A Girls Matte Finish Spray is a good dupe for NYX Matte Finish Spray. Now with that being said i found that using the L.A Girl Spray my makeup became oily vs. me not using after i finished my makeup. I'm not sure if using a matte primer and a matte finishing spray on top of that is the reason but i no long use a finishing spray. Now what i can say is that if you're just taking a day or two to give your skin a break from foundation you can spray this on after you wash and cleanse your face and it will totally mattify your skin for a few hours. With a disclaimer everyone's skin is different this is just what works for me. L.A Girl also has other great products as well which you can find HERE.
