Using a setting spray is really great to get rid of that ashy look after using a setting powder. It brings back that glow that you want to have when wearing make up. The make up forever spray was the 2nd one i've tried and I love it personally, it had my make up lasting 10+ hrs. Right now i'm using MAC fix+ and I love it as well. Tbh I don't know what one is better, they're both great and I want both in my collection, only thing is that the fix+ is cheaper, more product for a cheaper price and still works great.
