Nip+Fab viper venom blurring shot

[CupofBeans]

Can anyone tell me what it is? Is it a primer type to use before makeup, like a temporary fix or a treatment?
I’ve bought it with the pore free kit and the instructions tell you how to use but aren’t really clear as to what it is. So unsure if it’s best to use at night or morning or both

Anyone?

I have just bought it and used it twice. Even though it’s called a serum I think it’s a primer and that’s how I used it. Am impressed with it so far.

Sorry just noticed your reply. Do you mix it with moisturiser to use as a primer or just on its own?
