I got Xeomin Botox right before fine wrinkles appeared on my forehead, and I'm very satisfied. I get it every six months, and I highly recommend getting Botox for preventive purposes even if you're in your early 20s! I got it with Xeomin because it will last for a long time. For calves, which require a large dose, I recommend getting it done properly with a small injection, and for Botox injected into the face, I recommend getting it with Xeomin, which I don't tolerate well.
