I have had injections twice now and the results are amazing. I have a deep line by one of my brows that bothers me and seems to get deeper as I age. I have spent hundreds of dollars on expensive creams and ointments that have done absolutely nothing. For the cost of just one high dollar but ineffective cream, my brows were smoothed almost instantaneously. Just a couple of quick pinch like injections...and viola! Wrinkle gone. It's amazing!
