The results of a study have shown that an open Restylane syringe can remain sterile for up to nine months. Neither Restylane nor Restylane Silk, nor Restylane Lyft contain animal proteins, so there is little chance of an allergic reaction and no testing is required before the injection. The formulas are highly biocompatible, meaning that they will be metabolized by the body over time. Restylane typically lasts for six to eight months, while Restylane Silk and Restylane Lyft can last for eight to ten months.
In a culture medium, small amounts of the remains of 31 hyaluronic acid fillers, which had been used for facial filling, were inoculated. The fillers were stored in their original syringes at room temperature or in a refrigerator at 4°C for a period ranging from one week to 12 months after initial use. When you attend an appointment, we will discuss the different lip filler options available, including all Restylane and Juvederm dermal fillers. A single syringe will be used to deliver small amounts of the filler to specific treatment areas in order to achieve the best results.
