How to achieve that dewy skin.
You’ve heard the usual about getting good skin. Hydrate. Moisturize. Drink lots of water. If you have oily skin, use an oil free day moisturizer.
Now, I’ll teach you two ways to speed up the process and cheat your way to that perfect “glow”:

Image 1: You see more glow all over her face. In this case, I love using Nars Orgasm Illuminator mixed in with my foundation (dime size amount). A little of this product goes a long way. Another great option is Laura Mercier Illuminator. This comes in a few shades, so find what suits you best.

Image 2: You see “the glow” on peaks of her face. To achieve this look, I love using MAC cream color base in Hush (peachier tone). If you have a lighter skin tone, use Shell or Pearl. Using my fingers, I tap lightly into the cream color base and dab into the inner tear duct, under the brow, along the cheek bones, and bridge of your nose.
Overall effect is to give you that fresh faced look. It will definitely “brighten” you up!:)
