As promised here’s a colour swatch and comparision of the Garnier BB-Cream in Light and the Maybelline BB-Cream in Light.
On the top is the Garnier one and on the bottom the Maybelline one
As you can see the top one is clearly visible while the bottom one is almost completely blended. So the maybelline one was a far better match for me.
I can’t say yet how it works since I’ve only used it ones. So I’ll get back on that.
