I used to wear prescriptives foundation, it's very light. But could still feel it, kwim?
I just had my makeup done at the Laura Mercier counter and I Love love it. It's like i dont even have foundation on. I use a foundation primer and put tinted moisturizer on over it. I would highly reccomend it. I think there's a thread on here for the brand line, thats what made me pick LM.
