Restylane Silk is the first product to receive FDA approval for Restylane products. It was developed with the express purpose of providing a modest enhancement of the lips and reducing the appearance of wrinkles around the mouth. It creates a result that is softer and more precise than other Restylane products since it is made up of a gel that is smaller and smoother than other Restylane products. It is wonderful for plumping your pout and smoothing creases around your mouth, and it is ideal for restoring and enhancing the appearance of your lips.
