A while ago I tested out Garnier BB cream in medium. It was ok but I wasn't over thrilled with it and I didn't get that glow that other bloggers professed to have.
Clearly I was using the wrong colour.
Maybellines BB Cream in Dark is more up my pigment ally. It's a much lighter formula than Garnier, perhaps even a little runny, however it moisturises my skin really well. I don't look like I'm wearing make-up when I've got it on but I think I definitely look bright - glow achieved! Plus it contains 30 SPF which - for a burner like me - is an nice added bonus
