woman wondering what dermal fillers are

What Are Dermal Fillers? Hyaluronic Acid Explained and More

01 April

What you need to know about hyaluronic acid

 

Hyaluronic acid (HA) is a substance that is naturally present in the human body. HA is a naturally occurring sugar found in the body that retains water. It is found in the highest concentrations in fluids in the skin, but is also found in the eyes, cartilage, and various other areas and cells in the body.

 

The vital differences between hyaluronic acid-based fillers are: source of HA, concentration of HA, the particulate quantity of HA, whether the HA is cross-linked, the type of cross-linking agent used, whether the HA is monophasic or biphasic, if the HA is mixed with anesthetic. These differences determine the indications of the filler.

 

Particle sizes

 

Various companies, including Allergan, Galderma, and Merz, produce dermal fillers that contain non-animal HA gels. The particle size refers to the size of the hyaluronic acid molecules. Larger molecule sizes are generally used for deep wrinkles or volume restoration, while smaller molecule sizes are used for superficial corrections. As well, some dermal fillers also contain a mix of molecule sizes. Juvederm, Belotero, and Restylane all manufacture a range of fillers that contain various HA molecule sizes to target specific aging concerns.

 

HA concentration

 

The concentration of hyaluronic acid in a filler refers to how much HA is used in the formulation. This concentration can be anywhere from 13mg/ml to 24mg/ml, for example. 

 

What to expect after an injection

 

Post-injection, you can expect to experience some pain or tenderness, redness, swelling, and possibly itching.

If symptoms persist or worsen in the days after the treatment, you should contact your physician.


Choosing a dermal filler based on the severity of wrinkles

It’s important to recognize that there is not 1 filler that can alleviate all concerns. Different fillers have different functions and the appropriate filler must be selected according to the concern. Some fillers may be formulated to correct a number of concerns, while others may target 1 specific concern.

Your doctor will choose a filler that best suits your needs.
