You are very right. Yes, swelling is part of lip injection but your is dramatic. You have received very large volume of fillers and you have absolutely all rights to be upset. It is a common practice to push as much product as possible to sell as much as possible without regard to aesthetics or potential complications. Fortunately, those injectors represent a rapidly disappearing fraction of doctors. Always ask for your injector's before and after photos of previous cases. It will take you a brief moment, one look at the results, and you will know if it is appropriate for you. The best way to find someone is through the word of mouth. Avoid marketing, ads and self promotions! Meanwhile, apply ice and treat your lips gently. You should also notify your injector. If after several days you are still not satisfied, your filler can be rapidly reversed with enzyme hyaluronidase. It shouldn't cost you anything to dissolve it. If you get to this point you should insist of having your money back. It is not your fault. It is not filler's fault. You didn't have un unexpected "reaction" to filler. What you have is the most common consequence of ....filler abuse. It was your first injection and, I assume, you have completely relied on you injector's expertise. I'm sorry it happened to you! It shouldn't! Good luck!
