cosmetic and dermal fillers are a great way to prevent the look of aging while giving definition to areas on the face and neck. cosmetic fillers are measured in units and are used to smooth and prevent wrinkles in areas around the eyes, forehead, neck, and mouth. Facial fillers are used to ‘fill in’ areas that have lost volume due to the aging process or to contour the face and are measured in a number of syringes. Fillers can be used in the cheeks, lips, temples, and marionette lines. This can be used as an important part of cosmetic dentistry as well.
