Botox and dermal fillers are a great way to prevent the look of aging, while giving definition to areas on the face and neck. Botox is measured in ‘units’ and is used to smooth and prevent wrinkles in areas around the eyes, forehead, neck and around the 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 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.
