I have combination skin & I am 42. I would like to go d a foundation that gives a dewy look. Not too heavy & not too greasy. I am currently using Lancome's teint idole 24 he but it is matt looking. I can't get a match in their Teint Miracle. I don't mind if it's a cheap or expensive brand.
I currently use Lift Lumiere by Chanel (shade 0.5 Faience) and am very happy with it - it gives a glowy look.
I also find that using a primer/cream that gives a glow under matte foundation produces good results on my normal/dry skin. The ones I've liked are Les Perles Meteorites pearl primer and Leading Beauty Farms cream (I get a lot of higher-end samples), but I'm sure cheap ones would work equally well. Try them under your current foundation?
I sort of agree with Dona but I mix an illuminating fluid into my foundation before apply it. About 2 parts foundation to 1 part fluid. I just use a cheapish illumination fluid from Boots, I cant remember the name but it was under a tenner. I used to use Revlon Skinlights fluid but Im not sure they still make it? I mix mine with my Estee Lauder Doublewear as I like its staying power (I have combination skin and find lots of foundations dont stay put) but want a more dewy effect. Works a treat
