Regarding lip augmentation, there are two options available:
1. Synthetic hyaluronic acid based fillers like Surgederm or Restylane , This fillers works on the red area of the lips, but is not permanent – The results of this synthetic fillers will disappear completely within a year.
2. Dermis Fat grafting – Normally the best option to choose: this is done with fat extracted from other parts on the patient’s body and then it would be processed and prepared to be inserted under the lip. There will be some degree of absorption of the fat injected but unlike fillers this grafting is mostly permanent.
In cases where the patient has lines above the upper lip; fillers would be the most recommended option as their absorption is more predictable but this will be determined when the patient is evaluated in person. The reason is because fat could have lots of absorption in that area which can make the results less predictable.
