How Long Does Fillers Take to Work

Dermal fillers have gained immense popularity in recent years for their ability to rejuvenate and enhance facial features without the need for invasive surgery. Whether you’re looking to plump up your lips, smooth out wrinkles, or add volume to your cheeks, dermal fillers can provide beautiful and natural-looking results. One common question people have about these treatments is, “How long does it take for fillers to work?” In this comprehensive guide, we’ll explore the various types of dermal fillers and their timelines for results, as well as what you can expect during the healing process.

Understanding Dermal Fillers

Before we delve into the timeline, let’s briefly understand what dermal fillers are and how they work. Dermal fillers are injectable substances that are used to add volume, contour, and smooth out specific areas of the face. They are commonly made of hyaluronic acid, a naturally occurring substance in the body, which attracts and retains moisture, giving the skin a plump and youthful appearance.

There are different types of dermal fillers, each designed for specific purposes. Some of the most common types include:

Hyaluronic Acid Fillers

These are versatile fillers used for lip augmentation, cheek enhancement, and reducing the appearance of fine lines and wrinkles.

Calcium Hydroxylapatite Fillers

These fillers stimulate collagen production and are often used for deep wrinkles and volume loss in the cheeks.

Poly-L-Lactic Acid Fillers

These fillers work over time to stimulate collagen production, making them ideal for addressing sagging skin and restoring facial volume.

Polymethylmethacrylate (PMMA) Fillers

PMMA fillers are considered semi-permanent and are used for deep wrinkles, acne scars, and contouring.

Now, let’s explore the timelines for these different types of fillers:

Hyaluronic Acid Fillers

Hyaluronic acid fillers are among the most popular and widely used fillers due to their versatility and minimal downtime. The results of hyaluronic acid fillers are often visible immediately after the treatment. You’ll notice a significant improvement in volume and a reduction in lines and wrinkles right away. However, it’s essential to keep in mind that the initial swelling and redness from the injections may temporarily mask the full results.

Over the course of a few days to a week, the initial swelling will subside, and the filler will settle into its final position. At this point, you’ll be able to appreciate the natural-looking results that hyaluronic acid fillers provide. These results typically last six months to a year, depending on the product used and the area treated.

Calcium Hydroxylapatite Fillers

Calcium hydroxylapatite fillers, such as Radiesse, work differently than hyaluronic acid fillers. While you may see some immediate improvement in volume, the true results become more apparent over time. This filler stimulates collagen production, which takes several weeks to months. As collagen continues to develop, you’ll notice a gradual improvement in the treated area’s texture and volume.

The full effects of calcium hydroxylapatite fillers can last up to a year or more, making them an excellent choice for those seeking longer-lasting results.

Poly-L-Lactic Acid Fillers

Poly-L-lactic acid fillers, like Sculptra, are known for their ability to restore lost facial volume gradually. Unlike hyaluronic acid fillers, the results are not immediate. Instead, you’ll need multiple treatment sessions spaced a few weeks apart to achieve the desired outcome.

Over several months, as collagen production is stimulated, you’ll notice a subtle but significant improvement in facial volume and skin texture. The results of poly-L-lactic acid fillers can last up to two years or more, making them a popular choice for those who prefer a longer-lasting solution.

Polymethylmethacrylate (PMMA) Fillers

PMMA fillers are considered semi-permanent and work by adding volume to the treated area and stimulating collagen production. The initial results are visible immediately after treatment, but the full effects become more apparent over time as collagen continues to grow.

Patients can expect PMMA filler results to last for several years, making them a suitable option for those who want a longer-term solution. However, it’s essential to note that PMMA fillers are not easily reversible, so careful consideration and consultation with a skilled injector are crucial before opting for this type of filler.

What to Expect During the Healing Process

Regardless of the type of filler used, there are some common experiences during the healing process. After the injection, it’s normal to experience some swelling, redness, and bruising at the injection site. These side effects are usually mild and temporary, typically resolving within a few days to a week.

To minimize swelling and bruising, you can apply ice packs to the treated area and avoid strenuous exercise and alcohol for the first 24-48 hours. It’s also advisable to follow any specific post-treatment instructions provided by your injector.

Potential Risks and Complications

While dermal fillers are generally considered safe when administered by trained and experienced professionals, like any medical procedure, they come with potential risks and complications. It’s crucial to be aware of these risks and have a thorough discussion with your injector during the consultation to make an informed decision. Here are some of the potential risks and complications associated with dermal fillers:

Bruising and Swelling

After the injection, it’s common to experience bruising and swelling at the treatment site. This is usually mild and temporary, resolving within a few days to a week.

Applying ice packs and avoiding blood-thinning medications or supplements before the procedure can help reduce the risk of significant bruising and swelling. Your injector may also recommend arnica supplements or topical treatments to expedite healing.


There is a slight risk of infection at the injection site. While infections are relatively rare, they can lead to localized swelling, redness, and tenderness.

To minimize the risk of infection, it’s crucial to receive treatments from a licensed and reputable provider who follows strict hygiene protocols. Patients should also follow post-treatment care instructions meticulously to keep the treated area clean and free from contamination.

Allergic Reactions

Although uncommon, some individuals may experience allergic reactions to the filler substance. Symptoms may include redness, itching, or hives at the injection site.

To mitigate this risk, your injector will inquire about any known allergies during the consultation. They may also conduct a patch test to assess your sensitivity to the filler material. In the event of an allergic reaction, appropriate treatments, such as antihistamines or corticosteroids, can be administered.

Vascular Complications

In rare cases, dermal filler injections can inadvertently affect blood vessels, leading to complications like vascular occlusion or ischemia. This can result in tissue damage and, in severe cases, necrosis (tissue death).

Proper injection technique, including aspirating before injecting and using the cannula technique when necessary, can reduce the risk of vascular complications. Injectors should also have a thorough understanding of facial anatomy to avoid critical vessels.

Lumps and Irregularities

Dermal fillers can sometimes result in the formation of small lumps, bumps, or irregularities under the skin, known as nodules.

Skilled injectors are careful to distribute the filler evenly and massage the treated area to minimize the risk of nodules. If they do occur, they can often be dissolved using hyaluronidase, an enzyme that breaks down hyaluronic acid fillers.


In some cases, fillers may migrate from the injection site to unintended areas, leading to asymmetry or undesirable results.

Proper injection technique and a thorough understanding of facial anatomy are crucial in preventing filler migration. In cases of migration, adjustments can often be made during a follow-up appointment.

Granuloma Formation

Granulomas are small, inflammatory nodules that can develop months or even years after filler injection, usually as a response to the filler material.

While granulomas are rare, they can be challenging to treat. It’s essential to report any unexpected changes in the treated area to your injector promptly. Treatment may involve steroids or other interventions to resolve the issue.

Under- or Over-Correction

Achieving the desired level of correction can be challenging, and there is a risk of under-correction (not achieving the desired result) or over-correction (resulting in an unnatural appearance).

Clear communication with your injector during the consultation is key to avoiding under- or over-correction. Experienced injectors will often start conservatively and build upon the treatment in subsequent sessions to achieve the desired outcome gradually.

Filler Dissolution

Depending on the type of filler used, it may be necessary to dissolve or adjust the filler if the results are not as expected.

Some fillers, particularly those made from hyaluronic acid, can be dissolved using an enzyme called hyaluronidase. Your injector can perform this procedure if necessary to reverse or adjust the effects of the filler.

Rare Side Effects

While extremely rare, some individuals may experience severe and unexpected side effects, such as vision impairment or anaphylactic shock.

Although these extreme reactions are exceptionally uncommon, it’s essential to choose a highly skilled and experienced injector who can respond promptly and appropriately if such an event were to occur.


The timeline for dermal filler results varies depending on the type of filler used. Hyaluronic acid fillers provide immediate results with minimal downtime, while calcium hydroxylapatite and poly-L-lactic acid fillers offer gradual improvement over several weeks to months. PMMA fillers provide semi-permanent results that can last for several years.

Before undergoing any dermal filler treatment, consult with a qualified and experienced injector to discuss your goals, expectations, and the best filler option for you. Keep in mind that individual results may vary, and it’s essential to maintain a healthy skincare routine and follow your injector’s advice for long-lasting and satisfying results.
