Presented is a new and revolutionary device for exercising the facial muscles and lips. It's simplistic in that it is finger and hand operated and uses a clothespin like action, pivoting over an axle, with a closing return spring to exercise the facial muscles and lips. The control of the Lip Builder is unique in that the user can do a full range of motion resistance exercises or hold a steady pressure against the resisting lips for isometric exercises, or one may vary the pressure against the lips as you exercise with a full range of motion thereby doing an isotonic exercise. Its handles are designed at an angle for the user to create a pulling away action from the gums to avoid any discomfort upon exercising and an opening is left upon fully closing the Lip Builder to avoid the user pinching his or her lips.
