Patty's #totd DIY Illuminator Illuminators are awesome and a great substitute for a tan in the Summer. Take a little bit of your liquid foundation and add a nice shimmering eye shadow to it. I recommend a light gold because it will bring more warmth into the illuminator. Loose powder will work for this too. All you do is scrape a small amount — about the size of your pinky nail — into the foundation. Be careful not to overdo the shimmer, because this will lead to your skin looking oily. Too much glow isn't a good thing!
