Types of Fillers and 4 Factors that Affect Their Longevity

4 Factors that Affect The Longevity of Filler


Dermal fillers are an important tool to create beauty and youth and duration is a key factor patients will often inquire about when getting this treatment. Dr. Rajani reviews the different types of facial fillers and four variables that can affect their longevity.


There are currently 4 different types of dermal fillers in the United States:

1. Hyaluronic Acid fillers: HA fillers include Restylane, Juvederm, and Belotero products. HA fillers typically last anywhere between 6-18 months.

2. Permanent fillers: Bellafill (Artefill) is permanent filler comprised of small “microspheres” made of polymethyl methacrylate (PMMA) and collagen derived from cows. When used appropriately, patients tend to age at a slower rate and skin looks better overtime.

3. Collagen Stimulators: Collagen stimulators like Sculptra contains poly-L-lactic acid (PLLA). Sculptra can last anywhere between 2-5 years. Patients typically need several sessions of Sculptra treatments to achieve their overall aesthetic goals.

4. Radiesse: This dermal filler consists of Calcium hydroxylapatite. Like Sculptra, Radiesse holds collagen-stimulating properties but fills with a gel composed of carboxymethyl cellulose (CMC) as a carrier. This filler lasts anywhere between 8-18 months.


4 factors affecting dermal filler longevity:

1. Skin damage: With more skin damage comes the need to use more product. Skin therapies are very important. With great skin, less product is needed overtime to achieve your aesthetic goals.

2. Hollows: When you experience hollowing in the face such as in the temples, you would generally need more product. The issue with this is you may not get enough product and maintenance can be a challenge due to cost. Combination treatments and multiple vials are keys to success; anywhere between 5-20 vials is normal.

3. Placement: Placement of fillers is important. The depth, where fillers are placed, and how they are layered affects longevity of the product.

4. Expectations: When a patient has an expectation to receive a lot of filler, for example, wanting a very high cheek, not only will a patient want more product but as the filler wears off and aging continues, touch ups would occur more frequently to maintain results.
