You probably needed 2 syringes

While injection techniques differ from doctor to doctor, when a patient feels that they didn't get enough of a result from Restylane after only 2 weks, it is almost always the case that they needed more product.

This is especially true the first time you have the product injected because the fat below the Restylane will push down just as much as the skin will push up. After the first injection, as long as you don't let it all dissolve away, a second injection can be layered on top of the firm layer of the first injection and get much more upward push on the skin, often with less product.
