Hey Lina! Ok I am a newbie, but I’ve been reading through the forums for a couple hours and I think I can answer your question. There’s two Instant Sexiness versions A and B. Apparently, A is more for the aggressive woman (think Angelina Jolie) whereas B is more for a girly woman (think Mariyln Monroe). A will give you more confidence, but B would make you seem sweeter.
From what I read, Instant Sexiness doesn’t really make you seem sexier to other people, but rather it makes them more happier and friendly towards you kind of like Instant Shine for men. It gives you a confident vibe that attracts other people.
