Hello Tluckhurst,First off, I would not recommend Restylane Lyft under the eyes. It is a very thick filler meant for deeper injections such as the cheeks and melolabial folds. I much prefer Restylane as it is thinner and less prone to prolonged swelling and lumps. Having said that, with filler injections you should see an immediate result. If you did not get the correction you wanted before you left, there will be some further improvement as the filler draws in water, but it won't be a drastic change. Before considering any touch ups, I do recommend you wait at least two weeks to let all of the swelling go away. Also, fillers don't remove the bags, they make for a softer transition between the bag and the nose by filling in the gap or tear trough between. Surgery is what would fully correct the bags. I hope this helps and good luck.
