I have two of these in different shades, a berry and a brown, both are shimmery which I like. Firstly I always line and fill my lips before using a lipstick and I have great success with this as it really helps to lock the colour in.
You have the colour on one end and the glossy balm on the other. I make sure the colour is dry before applying the balm. This lasts really well for me and all I need to do is apply more balm after I've eaten and I'm good to go. I wouldn't say it lasts 24 hours but then who wears lipstick that long anyway. I wish the balm was a bit longer.
