What is Restylane Kysse?
Restylane Kysse is an FDA-approved clear hydraulic acid injectable gel. It is made with the purpose of providing a gel injection that feels more natural and lasts longer with the help of crosslinking BDDE. Hydraulic acid is a type of sugar that naturally forms in the human body. A small amount of lidocaine is also included within the ingredients in order to help subdue the pain from the injection.
