Review (5/5): YES! You Can Feel It Working!
You definitely feel tingling and a slight to moderate stinging shortly after applying the cream. My face started looking healthier and more radiant within a few days after first using. I've also noticed that the fine lines on my forehead seem to be decreasing....YIPPEE!
But, be sure to heed the warnings about avoiding your lips or you'll end up with severely chapped lips like me, and always follow-up with sunscreen before going out in the sun.
