Have been trying instant shine for the past week n a half now. Didn’t really get any extraordinary results such as more attention from others. Or maybe it is because the sample given to me has a power of just 1x? 
How many spray do you use?
Remember, Shine is more to increase your confidence and boost your mood.
2 sprays. 1 on the neck, the other on the chest.
I’ve also been using Shine for a few months now. No extraordinary result but good mood a few minutes after applying. Put some on your wrist and rub them under your nose for example… and another spray on the sides of neck.
This is a personal suggestion that works great for me, I don’t know about others yet : pair Shine with TAK. I use 2 sprays of regular shine and 10 to 15 mcg of TAK.
It’s like a budget A314 to me.
And try to recap your week and see if there were not results that you 've missed.
