What are Dermal Fillers?

The dermal fillers Juvederm, Restylane, Perlane and Belotero are a product made of cross-linked hyaluronic acid.   

Hyaluronic acid is present throughout the body, but we inject a thicker version of it in to creases and wrinkles. 

Dermal fillers are injected in to “static” wrinkles, which are wrinkles not caused by muscle movement. These wrinkles are often caused by the inevitable loss of fat or bone in the aging face, or by long-term “dynamic” wrinkles that have become etched in to the skin (such as forehead lines or crow’s feet that have been there for too long to erase them with Botox or botulinum toxins). 

You can also use dermal fillers on sunken or hollow areas where there has been bone loss due to aging. 

The most common area to treat with dermal fillers is the nasolabial folds which run from the sides of the nose down to the sides of the mouth. We also treat “marionette lines” which run from the sides of the mouth down to the chin. 

Other commonly treated areas treated with dermal fillers include: cheeks, under the eyes, lips, lip lines, along the jawline, chin cleft, acne scars or other scars. These products are not FDA approved for these all of these areas, but it is done. 



Lidocaine is usually added to the filler to make the injection procedure more comfortable. It is possible to dissolve hyaluronic acid fillers if needed, although this is rarely necessary.  

Radiesse is a little different type of filler made up of calcium hydroxyapatite. For our purpose that means a few things: 1. It is a stronger, denser product that lasts longer than hyaluronic acid fillers and 2. It is not reversible, so if you don’t like it you have to wait several months for it to be re-absorbed. 3. There are certain areas where it is too thick to be used, such as in the lips, and under the eyes.


Dermal fillers are amazing at creating a younger, and less-tired look. Most patients are concerned that they will look fake or “overdone”, but this is never the case in my practice. 

With dermal fillers, you will often see how you are going to look right after your treatment, so there is immediate gratification. 

Dermal fillers do not last forever, and duration is often linked to amount of product used, but most procedures last 6-9 months, and if you get a touch up at 6 months your filler can last for 18-24 months.
