In order to obtain truly natural feeling lips, meaning full but still soft and supple lips, with movement that feels normal to the touch, lip augmentation must come from hyaluronic acid fillers (Juvederm, Restylane and the soon-to-be-approved belotero) or from fat grafts to the lips. Implants and long-lasting fillers like silicone can make the lips firm or feel like there are hard nodules or foreign objects in the lips.
