The biggest tips I have found the past year for bright dewy skin:
Get rid of foundation
and use concealer to cover your skin imperfections and/or a color correcting formula such as this or this. Show your skin!
A Sephora employee convinced me to use my Sephora coupon on this color correcting cream that goes from green (cancels redness) to your flesh tone. This is truly your skin but better! It has SPF and nutrients for keeping skin plump and keeping it moisturized. The flesh color it fades too really does last all day. I've never seen anything like it, it's really amazing. It doesn't work well on extremely dark skin, I noticed this when the sales rep put it on her hand. I then put some concealer under my eyes and over any acne if I have some that day.
Use cream products: Highlighter, Blush, and Bronzer
(If you are oily you might need to use a powder over your T zone)
The RMS highlighter is a beauty cult favorite because it has zero glitter in it and simply just looks dewy. It will last you all day as well. I often find the powder highlighters are too much for me on a day to day basis because they contain glitter and in clinic I don't want to be wearing glitter. They work well in different environments, but this zero glitter formulation is my favorite!
(the brown pot is not bronzer in my picture, it is eyebrow pomade)
In case you want to LOL at me, I included some pictures. This is so embarrassing, by no means am I a makeup model!
Whoops somebody send me a beauty blender. That blush spot on the cheek needs some help.
