The Science Behind Dermal Fillers: How Do They Work?

Dermal Fillers in Bay City, MI

In the ever-evolving world of cosmetic medicine, dermal fillers have become a popular solution for those seeking to reduce the appearance of fine lines, wrinkles, and other signs of aging. They also enhance and contour facial features like lips and cheekbones. But have you ever wondered how these substances work their magic beneath the skin’s surface? Let’s delve into the science behind dermal fillers and understand their mechanism of action.

What Are Dermal Fillers?

Dermal fillers, commonly called “fillers,” are biocompatible substances injected under the skin to restore volume, smooth out wrinkles, and rejuvenate facial appearance. These fillers can be made from various materials, but the most common ones are hyaluronic acid, calcium hydroxylapatite, poly-L-lactic acid, and polymethylmethacrylate beads. Dermal fillers can treat many areas, including the lips, cheeks, nasolabial folds, marionette lines, and under-eye hollows. 

How Do Dermal Fillers Work?

The working mechanism of dermal fillers depends mainly on their composition:

Hyaluronic Acid (HA) Fillers

Hyaluronic acid is a naturally occurring sugar in our skin that helps retain moisture and maintain skin elasticity. As we age, the levels of HA decrease, leading to loss of volume and the formation of wrinkles. When HA fillers are introduced into the skin, they attract water and expand, instantly filling in wrinkles and restoring lost volume. HA fillers like Juvederm and Restylane are commonly used to treat facial wrinkles and nasolabial folds and augment lips or cheekbones. The effects of HA fillers can last anywhere from six months to two years, depending on the type and location of the injection.

Calcium Hydroxylapatite Fillers

Calcium hydroxylapatite is a mineral found in human bones. In dermal fillers, it is present as tiny, spherical particles suspended in a gel. When injected, it adds volume and stimulates the body’s collagen production, a protein responsible for skin strength and elasticity. This type of filler, like Radiesse, is typically used for deeper lines and wrinkles and to enhance cheekbones. The effects can last up to 12-18 months.

Poly-L-lactic Acid Fillers

Poly-L-lactic acid is a biodegradable synthetic substance. Unlike the immediate volume addition seen with HA and calcium hydroxylapatite fillers, this filler works more gradually by stimulating collagen production over time. Sculptra Aesthetic is a known poly-L-lactic acid filler used to treat deep facial wrinkles and restore facial volume loss due to aging. The results are longer-lasting, with effects visible for up to two years.

Polymethylmethacrylate (PMMA) Beads

PMMA is a synthetic, biocompatible material used in medicine for decades. In dermal fillers, PMMA beads are suspended in a collagen gel. Over time, the gel breaks down, but the PMMA beads remain, providing a permanent support structure and stimulating the production of the body’s natural collagen. Bellafill is an example that combines collagen with PMMA beads to treat deep wrinkles and acne scars. This type of filler offers semi-permanent to permanent results.

What Are Some Benefits of Dermal Fillers?

Dermal fillers offer various benefits for individuals seeking non-surgical facial rejuvenation:

Minimal Downtime

Dermal filler treatments are minimally invasive and typically require little to no downtime. Patients can return to their daily activities shortly after the treatment.

Customizable Results

Dermal fillers are versatile and can be tailored to meet individual aesthetic goals. We can adjust the type and amount of filler to achieve a natural and personalized look.

Minimal Discomfort

Many dermal fillers contain a local anesthetic (lidocaine) to minimize discomfort during the injection process.

Immediate Results

You can often see immediate improvements in your appearance after a dermal filler treatment.


Dermal fillers can address various cosmetic concerns, including enhancing lips, defining cheekbones, filling hollows under the eyes, and improving facial symmetry.

Who Is a Good Candidate for Dermal Fillers?

Dermal fillers have become increasingly popular in aesthetic medicine for their ability to rejuvenate the face by restoring volume, smoothing out wrinkles, and enhancing facial contours. A good candidate for dermal fillers is typically someone who is in good overall health and has realistic expectations about the treatment’s outcomes. They may have noticeable facial wrinkles, lines, or hollows due to aging, weight loss, or other factors.

Some candidates seek to enhance or refine specific facial features like lips or cheeks. It’s essential that the individual has no allergies to the filler components and no active skin infections or inflammatory conditions in the treatment areas. Furthermore, those who are pregnant, breastfeeding, or have certain underlying medical conditions may not be suitable candidates. It’s imperative to have a thorough consultation with us to determine candidacy and to understand the potential risks and benefits associated with dermal fillers.
