I bought 2 boxes of Revolax Sub Q and 2 boxes of Revolax fine. It was super numbing with the lidocaine and I used the Sub Q deep in the apple of my cheek just above the bone and I also used it in my lips (NOTE- USE A TINY AMOUNT! LOL) I used a little too much and my lips were just too big so it works very well! You don't need a lot! And in the lips, don't put it in deep, go shallow so you don't hit any veins. I also bought Liporase and that worked very well- make sure you dilute it very well! I filled up a little vile with saline then took almost all of it out with a needle and tossed it, then I diluted the tiny bit that was left in the bottle with more saline until the vile was almost full and used that and just used a TINY bit in my lip and it worked great. DO NOT USE A LOT and make sure you DILUTE IT VERY WELL- it can dissolve your natural hyaluronic acid and make your skin look old, wrinkly and deflated.
