I'm all for having skin that looks like it has that glow.  I've gone through many products but I'm not a fan of the ones that give me an orange tint.  I like ones that can just emphasize the color I already have because that is much more flattering and natural looking than a color that is obviously not mine.  I don't like when I can tell someone has too much make up on (none of us do!) and sometimes people can take it overboard and have a totally different color on their face than their neck without even knowing it. 

So I did a hair show this past Wednesday and I was getting my makeup done and out comes the wonderful product!!  Belightful by Mac is what she used on me.  Runs at $21... not bad!

If your looking for a less expensive one I also found another nice product at Sally's Beauty!  It was somewhere around $7.  It isn't listed online but it's by Palladio and it's a square pallet with about 5 different colors on it that mix together to get a nice glow!  

I will attach a picture of me at the hair show that shows the glow of the makeup well.
