Or any injection in general? And how long does it last. I want to get injections in my cheeks jawline and around the chin, something to slim my face and make my face look more sculpted, I'm unsure on whether I should get an actual permanent plastic surgery, or regularly go back and get it redone, how many mls can you get in one sitting and can you achieve major results in that one sitting? And I want to know if it cost more for more mls?? Thankyou!
