Maybe you have loads or maybe just the one, but what do you use and what's your opinion of it?
Here's mine.
1) Bobbi Brown foundation stick in Warm Sand - love it, very natural when blended with warm hands.
2) Bobbi Brown Luminous foundation in Warm Sand - above average, good colour, not all that luminous or moisturizing.
3) MAC Mineralize Satinfinish SPF15 in NC20 - Meh, OK, not all that blown away by it, says it's for normal/dry skin but in my experience only if I've slapped on loads of moisturizer beforehand, but I keep on using it on an everyday basis.
These are sitting out on my dressing table. In my drawer are some others that are currently demoted although I'm intending to bring some of these out once the weather improves.
They are:
1) Estee Lauder Doublewear in Fresco - slightly too dark, OK for Summer.
2) La Mer Fluid Tint in Light - excellent, light enchanced look.
3) Clarins Extra-Firming Foundation in 105 Nude - very good indeed and excellent colour match, don't know why it's here really as it looks fab on. Maybe a tad too makeup-y for me?
4) Dior Nude Natural Glow Hydrating Makeup in 023 - again, very good but maybe a bit too makeup-y again?
What have you got!
