Understanding How Dermal Fillers Break Down Over Time
Dermal fillers have become a popular solution for adding volume, smoothing wrinkles, and enhancing facial features. One common question people ask before undergoing filler treatments is whether the results are permanent or temporary. Specifically, does filler go away on its own?
In this post, we’ll explain how fillers work, how long they last, and what happens to them over time.
How Do Dermal Fillers Work?
Dermal fillers are injectable substances that add volume to specific areas of the face, smooth out wrinkles, or enhance facial contours through filler injections. Most fillers are made from hyaluronic acid (HA), a naturally occurring substance in the skin that attracts and retains moisture. Fillers can be used for a variety of purposes, such as plumping lips, contouring the cheeks, filling in hollow areas under the eyes, and smoothing nasolabial folds.
There are also other types of fillers, such as calcium hydroxylapatite and poly-L-lactic acid, which stimulate collagen production and provide longer-lasting results.
Does Fillers Go Away on Its Own?
Yes, dermal fillers do go away on their own over time. In some cases, patients may need to have the filler dissolved if the results are not as expected. Most dermal fillers are not permanent, and the body gradually metabolizes and absorbs them. How long they last depends on several factors, including the type of filler used, the area treated, and individual factors like metabolism.
Here’s a breakdown of how common types of fillers break down:
1. Hyaluronic Acid Fillers
Hyaluronic acid (HA) fillers, such as Juvederm, Restylane, and Belotero, are the most commonly used dermal fillers. Hyaluronic acid injections are known for their ability to increase lip hydration and stimulate collagen production. These fillers are temporary and dissolve naturally over time.
- How Long Do They Last? HA fillers typically last between 6 to 18 months, depending on the specific product used and the area treated. For example, fillers used in areas with a lot of movement, like the lips, may break down more quickly than those used in the cheeks or jawline.
- What Happens to the Filler? The body slowly absorbs and metabolizes the hyaluronic acid as it breaks down. The results will gradually fade, and the treated area will return to its pre-treatment appearance unless further treatments are performed.
2. Calcium Hydroxylapatite Fillers
Fillers like Radiesse use calcium hydroxylapatite, a substance that is naturally found in bones. This type of filler is also absorbed by the body but lasts a bit longer than HA fillers.
- How Long Do They Last? Calcium hydroxylapatite fillers last approximately 12 to 18 months.
- What Happens to the Filler? The filler is gradually broken down by the body, and as it dissolves, it also stimulates collagen production, which can provide continued volume and skin support even after the filler itself has been absorbed.
3. Poly-L-Lactic Acid Fillers
Sculptra is a filler made from poly-L-lactic acid, a biocompatible substance that stimulates collagen production over time. This type of filler provides more long-lasting results but takes longer to fully develop.
- How Long Do They Last? Poly-L-lactic acid fillers can last for up to 2 years.
- What Happens to the Filler? Unlike HA fillers, which provide instant results, poly-L-lactic acid works gradually. As the filler stimulates collagen production, the body breaks down the substance over several months, leaving behind a natural increase in volume from the collagen.
4. Permanent Fillers
While most fillers are temporary, some fillers, such as polymethyl methacrylate (PMMA), offer permanent or semi-permanent results. However, permanent fillers are less commonly used today due to the risk of complications and the difficulty of correcting the results if they don’t turn out as expected.
- How Long Do They Last? Permanent fillers do not dissolve and stay in the treated area unless removed surgically.
- What Happens to the Filler? Since permanent fillers don’t break down naturally, the results are long-lasting. However, as the face continues to age, permanent fillers may become more noticeable or require adjustments over time.
Factors That Influence How Long Fillers Last
Several factors can influence how quickly fillers break down in the body, including:
- Metabolism: People with faster metabolisms tend to break down fillers more quickly, which means they may need more frequent touch-ups.
- Location of Injection: Areas with a lot of movement, like the lips and mouth, often break down fillers faster than areas like the cheeks or under the eyes.
- Type of Filler: Different fillers have different longevity. Hyaluronic acid fillers generally last 6 to 18 months, while collagen-stimulating fillers like Sculptra can last up to two years.
- Lifestyle: Factors such as sun exposure, smoking, and hydration can affect how long fillers last. For instance, smoking can cause fillers to break down more quickly.
Can Fillers Be Dissolved If Needed?
For hyaluronic acid fillers, there is an enzyme called hyaluronidase that can be injected to dissolve the filler if the results are not as expected or if complications occur. Injectable fillers, such as hyaluronic acid and calcium hydroxylapatite, have different methods for removal if necessary. This enzyme rapidly breaks down HA fillers, returning the treated area to its natural state.
Other fillers, such as calcium hydroxylapatite or poly-L-lactic acid, cannot be dissolved in this way. These fillers must be allowed to break down naturally or surgically removed if necessary.
Safety and Risks
While dermal fillers are generally considered safe, it’s important to be aware of the potential risks and side effects. Understanding these can help you make an informed decision and ensure a positive experience with your filler treatment.
Common Side Effects and Complications
Common side effects of dermal fillers include:
- Swelling: Mild swelling at the injection site is common and usually subsides within a few days.
- Redness: Temporary redness can occur but typically fades quickly.
- Bruising: Some bruising may appear around the injection area but should resolve within a week.
- Pain or discomfort: Minor pain or discomfort at the injection site is normal and usually short-lived.
- Headache: Some individuals may experience a mild headache after treatment.
More serious complications, though rare, can include:
- Allergic reactions: Some people may have an allergic reaction to the filler material.
- Infection: Infections can occur if the injection site is not properly cared for.
- Scarring: Improper injection techniques can lead to scarring.
- Asymmetry or unevenness: Uneven distribution of the filler can result in asymmetry.
- Filler migration: In some cases, the filler may move from the injection site to another area of the face.
To minimize the risk of complications and ensure optimal results, it’s essential to choose a qualified and experienced injector. A skilled professional will be able to assess your needs, recommend the appropriate type of filler, and perform the injections safely and effectively.
Maintaining Filler Results Over Time
If you want to maintain your filler results, you will need periodic touch-up treatments as the filler naturally dissolves. Most people schedule maintenance treatments every 6 to 18 months, depending on the filler type and the area treated.
In addition to touch-ups, following a good skincare routine and maintaining a healthy lifestyle can help extend the longevity of your filler results.
Conclusion: Fillers Are Temporary but Effective
Dermal fillers provide a temporary yet effective solution for enhancing facial features, adding volume, and reducing wrinkles. While fillers do go away on their own as the body gradually absorbs them, the results can last anywhere from several months to two years, depending on the type of filler used.
If you’re considering dermal fillers, it’s important to understand how long they will last and what to expect as they naturally break down. Regular touch-ups and maintenance treatments can help you enjoy long-lasting, balanced results. Always consult with a certified professional to ensure you get the right type of filler for your specific needs and goals.
