This is a very well known product and I’d be surprised if you haven’t heard of Urban Decay’s All Nighter makeup setting spray.
This is the smaller bottle since I don’t use setting spray that often. I’d recommend going for this size rather than the full one unless you’re certain you’ll be using all of it.
It’s fairly pricey, available at Mecca cosmetics, and is a product almost worthy of the hype.
It’s good. Not brilliant, but good. It will make your makeup last longer, but I’m not sure it would survive an all nighter.
