What Are Dermal Fillers And How Do They Work
May 1, 2025
Types of Dermal Fillers
Dermal fillers are injectable substances used to enhance facial volume, reduce wrinkles, and contour specific areas. These gels, composed of various materials like hyaluronic acid, poly-L-lactic acid (PLLA), or calcium hydroxylapatite, work by plumping up skin and smoothing out fine lines and wrinkles.
Hyaluronic Acid Fillers
Hyaluronic acid fillers are a popular type of dermal filler known for their ability to attract and retain water. This makes them highly effective at plumping up the skin, reducing the appearance of wrinkles, and adding volume to areas like cheeks, lips, and under-eye hollows. Hyaluronic acid is naturally present in the body, playing a role in skin hydration and elasticity.
Collagen Fillers
Collagen fillers are another type of dermal filler that work by stimulating the production of natural collagen within the skin. Collagen is a protein that provides structure and support to the skin, giving it firmness and elasticity.
- These fillers typically contain bovine or porcine collagen, which is absorbed by the body over time.
- The process of absorption triggers the production of new collagen, leading to a gradual increase in skin fullness and volume.
Poly-L-Lactic Acid (PLLA) Fillers
Poly-L-lactic acid (PLLA) fillers are a unique type of dermal filler that work differently compared to hyaluronic acid or collagen fillers. Instead of immediately adding volume, PLLA fillers stimulate the body’s own collagen production over time.
When injected, PLLA particles act as a scaffold, triggering the skin’s fibroblasts (cells responsible for collagen production) to create new collagen fibers. This gradual collagen synthesis leads to a subtle yet lasting increase in skin volume and firmness.
PLLA fillers are often used to address deeper wrinkles, facial lines, and areas that require long-lasting volumization, such as the cheeks or jawline. Because they stimulate collagen production, the results from PLLA fillers tend to be more natural-looking and long-lasting compared to hyaluronic acid fillers.
Other Types of Fillers
Calcium hydroxylapatite (CaHA) is another type of dermal filler gaining popularity. It’s a synthetic material that mimics the body’s natural calcium deposits found in bones and teeth. When injected, CaHA particles act as tiny volumizers, filling in wrinkles and enhancing facial contours.
Unlike hyaluronic acid fillers, CaHA doesn’t attract water but provides direct volume augmentation. It also stimulates collagen production, leading to a more gradual and natural-looking enhancement over time. CaHA is often used for correcting moderate to severe facial wrinkles, restoring lost volume in the cheeks, and enhancing the jawline.
Other types of fillers exist, including polymethyl methacrylate (PMMA) and fat grafts. PMMA, also known as silicone gel, is a semi-permanent filler that provides significant volume enhancement. Fat grafting involves transferring a patient’s own fat cells to specific areas of the face to add volume and improve contour.
How Dermal Fillers Work
Dermal fillers are injectable substances used to enhance facial appearance by plumping up skin, smoothing wrinkles, and adding volume to specific areas. These gels contain various materials, such as hyaluronic acid, poly-L-lactic acid (PLLA), or calcium hydroxylapatite, each working in a unique way to achieve desired results.
Subcutaneous Injection Technique
Dermal fillers are injected into the skin using a fine needle to achieve various cosmetic enhancements. The subcutaneous injection technique involves inserting the needle just beneath the surface of the skin, typically in the dermis layer, where collagen and elastin fibers reside.
The chosen filler material is then deposited at the target area, smoothing wrinkles, plumping up thin areas, or adding contour to facial features. The depth and placement of injections depend on the desired outcome and the type of filler used.
Filler Material Integration with Tissue
Dermal fillers integrate with tissue in various ways depending on their composition. Hyaluronic acid fillers attract and bind water molecules, increasing hydration and plumping up the skin.
- This natural process of swelling gives a subtle yet noticeable improvement to wrinkles, fine lines, and volume loss.
- Collagen fillers work by stimulating the body’s own collagen production.
- The injected collagen acts as a scaffold, prompting fibroblasts to create new collagen fibers, leading to gradual skin rejuvenation.
PLLA fillers, on the other hand, act as a biocompatible framework, triggering a long-term increase in collagen production over several months.
Calcium hydroxylapatite (CaHA) fillers provide immediate volume by directly filling in wrinkles and hollows. They also stimulate collagen synthesis for a more natural and enduring outcome.
Temporary vs. Permanent Results
Dermal fillers are designed to enhance facial appearance by plumping skin, smoothing wrinkles, and adding volume to specific areas. These gels can be made from various materials like hyaluronic acid, poly-L-lactic acid (PLLA), or calcium hydroxylapatite. Each material works differently to achieve desired results.
Hyaluronic acid fillers attract and retain water molecules, increasing hydration and plumping the skin. This natural process helps reduce wrinkles, fine lines, and volume loss, providing a subtle yet noticeable improvement.
Collagen fillers stimulate the body’s own collagen production. The injected collagen acts as a scaffold, prompting fibroblasts to create new collagen fibers, leading to gradual skin rejuvenation.
PLLA fillers act as a biocompatible framework that triggers a long-term increase in collagen production over several months, resulting in more natural and enduring outcomes compared to hyaluronic acid fillers.
Calcium hydroxylapatite (CaHA) fillers provide immediate volume by directly filling wrinkles and hollows. They also stimulate collagen synthesis for a more natural and lasting enhancement.
The duration of results from dermal fillers varies depending on the type of filler used. Hyaluronic acid fillers typically last 6 to 18 months, while PLLA fillers can produce long-lasting results that may last for years.

Addressing Volume Loss
Dermal fillers are increasingly popular for addressing age-related volume loss in the face. As we age, our bodies produce less collagen and elastin, leading to wrinkles, sagging skin, and a loss of facial definition. Dermal fillers can effectively combat these changes by replenishing lost volume and restoring a more youthful appearance.
One major benefit of dermal fillers is their ability to restore facial contours. As we age, areas like the cheeks, temples, and jawline tend to lose volume, leading to a flatter, less defined face. Fillers can be strategically injected to add volume to these areas, restoring lost definition and creating a more sculpted appearance.
Beyond contouring, dermal fillers can significantly reduce the appearance of wrinkles and fine lines. By plumping up the skin, they smooth out creases and create a smoother, more youthful complexion. This effect is particularly noticeable around the eyes (crow’s feet), mouth (smile lines), and forehead.
Another benefit of dermal fillers is their non-surgical nature. Unlike surgical procedures like facelifts, fillers can be administered in a quick outpatient procedure with minimal downtime. This makes them an attractive option for individuals seeking subtle improvements without the risks and recovery associated with surgery.
Smoothing Fine Lines and Wrinkles
Dermal fillers offer a range of benefits for enhancing facial appearance and addressing signs of aging. By plumping up the skin and smoothing out wrinkles, they can significantly improve facial contours, reduce the appearance of fine lines and creases, and restore a more youthful complexion.
One key advantage of dermal fillers is their ability to restore lost volume in areas like cheeks, temples, and jawlines. This helps redefine facial contours, creating a more sculpted and defined look. Fillers can also effectively minimize the appearance of wrinkles by plumping up the skin and smoothing out creases, particularly around the eyes, mouth, and forehead.
Furthermore, dermal fillers provide a non-surgical approach to cosmetic enhancements. Unlike surgical procedures, filler injections are relatively quick and painless, with minimal downtime. This makes them an appealing option for individuals seeking subtle improvements without undergoing invasive treatments.
