This is Mac's Fusion Pink Lipstick, it's a very bright medium warm pink with red undertones and subtle shimmer. I'm pretty sure this is a Pro store only item. It's an Amplified Finish so is super pigmented and very intense. There seem to be a lot of neon colours coming out this year and this one is perfect for summer. It goes on very opaque and lasts about 5-6 hours on me.
This lipstick is definitely not for the faint hearted but if you enjoy wearing bright shades is a lovely one to have in your make up bag. It's quite similar to something like Impassioned or Party Parrot so it's worth having a look in your kit before purchasing this one! I don't find it particularly hydrating or drying, so if you have dry lips you might need a bit of balm on before applying this.
