Benizake, I love your lips, I am going to order this week.  Any application tips?

As Karen mentioned earlier in this thread, try not to get anything inside your mouth. We don't want you to risk biting your lips for the next few months. All I did, and probably CM too, would be to apply the cream only on the outside part of the lip. But if you feel a bit daring, you can try applying it around the lips as well to see if you get any different results. But that would be entering new and unfamiliar territory. 
I just applied the cream 2 times a day after my meals and somehow got good results. The best tips of them all is probably that one bottle of IsoSensual Enhance will most likely last for many years if you only use it on your lips. Maybe even decades. After 3 weeks you should probably apply the cream once or twice a week just to be safe. But the maintenance part is also unfamiliar territory to us. I stopped applying the cream after the 3 weeks and will do so for the foreseeable future to test how long the effects last. And so far, I can see no difference at all. So be prepared to keep those lips for at least a few months.
That's about it. Good luck!
