It's always a struggle finding a good foundation with the right undertone when shopping for darker skin. Below are a few of my favourite brands that have a decent range of shades, which I use personally. (I have a yellow undertone and combination/oily skin):
What are your favourites? I'd love to know!
I'm on the darker end of olive in complexion (I look paler in my profile pic than I really am!) and I'm loving the Becca Aqua Luminous range! So nice and light (in weight) with a bit of a glow.
NARS is my holy grail because of its yellow based shadesSheer Glow - BarcelonaRadiant Tinted Moisturiser - St Moritz
Oooh I love NARS All Day Luminous Foundation in Tahoe and NARS Velvet Matte Skin Tint in Malaga. Bobbi Brown and NARS are both genius at yellow-based foundations for darker skin.
