Over the past several years, options for injectable fillers have become significantly refined. The majority of fillers used today are forms of hyaluronic acid (HA). Hyaluronic acid is a substance that occurs naturally in all mammals and has been successfully and safely cloned in the laboratory. Because pure hyaluronic acid would be broken down by the body in about 24 hours, HA injectables have been modified to increase their stability over time by a process called cross-linking. The different HA products differ in molecule size as well as amount of cross-linking. These variations cause changes in characteristics such as “thickness” of the product and how long it remains in the body. The average treatment results last around six months, although the length the product remains can vary based on individual factors, the product chosen, and the area being treated.

The most popular types of HA injectables are Restylane/Restylane Lyft and Juvederm/Voluma. These products are made by different companies who all, of course, claim that theirs are the best. At the time of an individual consultation, Dr. Rapaport will advise which type of filler is best for a given area. Products such as Voluma and Restylane Lyft are more “robust,” and therefore they are commonly injected deeper, especially near the bones of the midface. This creates a very natural enhancement of the area and restoration of volume which is naturally lost as part of the aging process. Restylane and Juvederm are “thinner” products, which are used more superficially, as appropriate. Restylane Silk is a very new formulation of Restylane, specifically designed for the lip area. Dr. Rapaport is one of the first physicians in the United States to use Restylane Silk. Belotero is yet another HA product which is often favored in the lower eyelid, “tear trough” area. In addition, we recently became one of the first practices in NYC to offer Volbella, a brand new HA that is very low viscosity and offers excellent results for lip enhancement and the improvement of fine lines.

Dr. Rapaport uses these types of injectable fillers in many areas of the face:
  • Lip Augmentation
  • Restore lost volume in the cheeks/midface and other areas of the face
  • Make the jowls appear less pronounced
  • Smooth wrinkles and folds
  • Droopy mouth corners
  • Nasolabial folds (folds around the nose)
  • Non-surgical rhinoplasty (make the nose appear more narrow or more straight)
  • Non-surgical chin augmentation
  • Non-surgical blepharoplasty (reduce hollowness under the eyes)

How Can I Prepare for an Injectable Filler Treatment?

Even though no allergy testing is needed, before having any HA filler injections, patients should avoid using aspirin products, Vitamin E supplements and other medications that can thin the blood and may increase bruising.
