Most Common Filler Injection Side Effects

If you’ve ever scrolled through instagram or flipped through a magazine, you’ve probably noticed the growing trend of filler injections. From flump lips to smoother skin, they seem like a quick fix for enhancing natural beauty.

But let’s be real, anything that promises big results in a short amount of time can come with its own risks. Don’t get it wrong, fillers can work wonders when done right but they’re not completely risk free.

That’s why it’s so important to go in with your eyes wide open (and not just focused on the “after” photos). Today, we’re diving into what filler injections are, the potential filler injection side effects -what’s normal, what’s not, what are the filler injection side effects in the long term and most importantly, what you can do to stay safe.

What are Filler Injections?

As you age, your skin starts to lose subcutaneous fat and essential proteins like elastin and collagen. Collagen is a protein that gives your skin its elasticity, firmness and keeps you looking young.

The loss of collagen leads to a thinner skin, sagging and the development of wrinkles. This is where filler injections come in. Filler injections, often called dermal fillers, are a popular non-invasive cosmetic treatment designed to enhance facial features , smooth wrinkles and restore volume lost due to aging.

These injections are performed by healthcare professionals who place the filler substance just beneath the skin targeting areas that need plumping or rejuvenations. The procedure is quick -usually just under 30 minutes with minimal recovery time, making it a go-to option for many seeking immediate results.

Types of Filler Injections

Many Canadians are hopping on the filler train, and for good reason—they can help you look refreshed without going under the knife. But before you book your appointment, let’s break down the types of fillers available and what they can do for you.

Dermal fillers can either come “off-the-shelf” (made from synthetic or naturally occurring substances) or be all-natural, like fat taken from your own body. Your healthcare provider will guide you on what works best for your unique face and goals. Here’s the scoop on what’s available:

Off-the-Shelf Fillers

Off-the-shelf fillers are pre-made and come in a variety of formulations. Each type serves a unique purpose, whether it’s smoothing fine lines or addressing deeper facial creases.

1. Hyaluronic Acid (HA)

Hyaluronic acid (HA) is a naturally occurring substance in your skin that helps retain moisture and volume. As we age, our body produces less HA, which can lead to dryness and wrinkles.

HA fillers, like Restylane® and Juvéderm®, replenish this lost hydration, giving your skin a plumper, more refreshed look.

• Best for: Adding volume to cheeks, plumping lips, and smoothing fine lines.
• Results last: 6 to 12 months, though newer formulations can last longer.
• Why it works: HA acts like a sponge, attracting water to hydrate your skin from the inside out.

2. Calcium Hydroxylapatite (CaHA)

CaHA fillers, like Radiesse®, are made from tiny calcium particles suspended in a gel. These fillers are denser than HA, making them ideal for addressing deeper wrinkles and adding structure to areas like the jawline.

• Best for: Reducing deep wrinkles and folds, such as smile lines or marionette lines.
• Results last: Around 12 months.
• Why it works: The calcium particles provide immediate volume while stimulating collagen production for longer-lasting results.

3. Poly-L-lactic Acid (PLLA)

PLLA fillers, such as Sculptra®, don’t just “fill” wrinkles—they encourage your skin to produce more collagen over time. This makes them ideal for long-term improvements in skin texture and firmness.

• Best for: Addressing severe volume loss and deep wrinkles.
• Results last: 2+ years, with gradual improvement over several months.
• Why it works: PLLA essentially “trains” your skin to rebuild its structure naturally.

4. Polymethylmethacrylate (PMMA)

PMMA fillers, like Bellafill®, contain tiny microspheres suspended in collagen. These fillers are semi-permanent, as the microspheres remain under the skin to provide lasting support.

• Best for: Long-lasting correction of deep wrinkles and acne scars.
• Results last: Up to 5 years.
• Considerations: PMMA is not typically the first choice due to a higher risk of complications, like lumps or nodules, if not administered correctly.

Autologous Fat Grafting

For those who prefer a more natural approach, fat grafting offers a unique solution. This procedure involves harvesting fat from your own body—often from the thighs or abdomen—via liposuction, and then injecting it into your face to restore volume.

• Best for: Filling in deep wrinkles, restoring volume loss, or contouring facial features.
• Results last: Typically permanent.
• Considerations: This procedure requires sedation and recovery time (about 1–2 weeks), so it’s not a quick fix.

How do Filler Injections Work ?

Filler injections work by introducing a gel-like substance into specific areas of the face using a cannula or a needle. This substance plumps the skin from the inside out, smoothing wrinkles , adding volume and filling hollow areas.

Filler injections target the underlying causes of aging, such as the loss of collagen, fat, and elasticity in the skin. Here’s a closer look at how they work and the procedure involved:

1. Plumping and Filling:
   Dermal fillers are gel-like substances that are injected beneath the skin. Once injected, the fillers act as a scaffold, adding volume to hollow or sunken areas and filling in wrinkles to smooth the skin’s surface.
2. Skin Hydration and Support:
   Many fillers have the ability to attract water molecules, which enhances the skin’s hydration and elasticity. This not only creates a fuller, more youthful look but also helps the skin maintain moisture over time.
3. Replacing Lost Volume:
   As we age, natural fat pads in the face shrink and slide downward, leading to a hollow or sagging appearance. Fillers replenish this volume, restoring the face’s natural structure and creating a refreshed look.
4. Wrinkle Reduction:
   Fillers target static lines—wrinkles that are visible even when the face is at rest. By lifting and smoothing these areas, fillers reduce the depth and appearance of wrinkles.

The Procedure: Step-by-Step

1.   Consultation and Planning:

Before the procedure, you’ll meet with a qualified healthcare provider (such as a dermatologist or cosmetic surgeon). During this consultation:

• Your provider will examine your face, discuss your goals, and identify areas to treat.
• They may mark specific injection points and take photos for reference.
• They’ll review your medical history, including any allergies, medications, or conditions that might affect the procedure.

2.   Preparation:

• The skin is cleaned thoroughly to prevent infection.
• A numbing cream or local anesthetic may be applied to minimize discomfort during the injections.

3.   Injection:

• Using a fine needle or cannula (a blunt-tip instrument), the healthcare provider injects the filler into targeted areas beneath the skin.
• The injection technique and depth depend on the area being treated and the desired result.
• The process usually involves multiple small injections to achieve a natural, even look.

What to Expect: You might feel a slight pinch or pressure, but most people find the procedure tolerable.

4.   Post-Injection Care:

• After the injections, the provider will gently massage the treated areas to ensure even distribution of the filler.
• The skin is then cleaned, and an ice pack may be applied to reduce swelling and bruising.

Filler Injection Procedure

What Happens After the Procedure?

• Immediate Results: Most people notice improvements right after the procedure, although mild swelling or redness is common.
• Minimal Downtime: You can typically return to your regular activities the same day, but it’s best to avoid strenuous exercise or excessive sun exposure for 24–48 hours.
• Follow-Up: Depending on your treatment plan, your provider may recommend a follow-up appointment to assess the results and discuss any touch-ups.

The Most Common Filler Injections Side Effects

Filler injections are generally safe, but like any cosmetic treatment, they come with some side effects that are important to be aware of. Most side effects are temporary and will resolve within a couple of weeks. Here are the most common ones you might experience:

• Redness: It’s common to see some redness around the injection site right after the procedure. It’s your body’s natural response to the small needle punctures. This usually disappears within a few hours to a couple of days.
• Swelling: Swelling is another common side effect, and it can last for up to two weeks. It’s especially noticeable in areas like the lips or under the eyes. A cold compress or ice pack can help ease this.
• Pain: Mild discomfort or tenderness can occur where the filler was injected. This can usually be managed with over-the-counter pain relievers, but it should subside within a few days.
• Bruising: A little bruising can happen, especially if the needle hits a small blood vessel. This is completely normal and typically fades away in about a week or two.
• Itching: Your skin may feel a little itchy after the procedure, especially if you’re sensitive to the injection itself. If this happens, try not to scratch it, as that can lead to irritation or even an infection.
• Rash: In rare cases, you might develop a rash around the injection site, but this typically goes away on its own. If it doesn’t, consult your healthcare provider.

These side effects are typically mild and manageable. They’re a bit like the way your skin reacts after a hard workout—there’s a little discomfort, but it’s usually nothing to worry about.

Rare Side Effects of Filler Injections

While rare, some side effects can be more serious. These tend to happen in very specific situations, but it’s important to be aware of them so you know when to seek immediate help.

• Infection: Though uncommon, infections can occur if bacteria enter the skin during the injection process. Proper aftercare and hygiene can help prevent this. If you notice redness, warmth, or pus around the injection site, contact your provider right away.
• Leakage of the Filler: Sometimes, the filler may leak from the injection site, which can cause lumps or an uneven appearance. This is more likely to happen if the filler hasn’t been injected deep enough into the skin.
• Nodules or Bumps: In some cases, small lumps or bumps can form under the skin. These may require a small procedure to remove or smooth them out. If you notice anything unusual under your skin, talk to your healthcare provider.
• Granulomas: This is an inflammatory reaction that occurs when the body recognizes the filler as a foreign substance. Granulomas can cause swelling or lumps and may require treatment to reduce the inflammation.
• Movement of the Filler: Sometimes the filler can move from one area to another, which can result in an uneven look. This is more likely if the filler is too thin or if the treated area is massaged too soon after the procedure.
• Injury to Blood Vessels: In very rare cases, fillers can accidentally be injected into or near a blood vessel, which can cause complications like bruising, swelling, or even tissue damage.
• Blindness: This is an extremely rare but serious side effect. It happens if the filler is injected into a blood vessel that leads to the eyes, blocking blood flow and causing vision loss. Immediate medical attention is required.
• Tissue Death: If blood flow is blocked due to incorrect injection techniques, the surrounding tissue could die. This is a very rare complication, but it highlights the importance of choosing an experienced and qualified practitioner.

Filler Injection Side Effects in the Long Term

While the immediate side effects are mostly temporary, it’s also important to consider what might happen long-term. Here are a few things to keep in mind:

• Asymmetry: Over time, the filler can break down unevenly, which might lead to an asymmetrical appearance. This can often be corrected with additional treatments, but it’s important to choose a skilled injector to minimize this risk.
• Lumps or Bumps Under the Skin: In some cases, lumps or bumps may persist long-term if the filler doesn’t settle well in the skin. These can be treated by dissolving the filler or using massage techniques.
• Skin Damage or Scarring: While rare, if the filler is injected too deeply or incorrectly, it could cause skin damage or scarring that may last for a long time. Always ensure your practitioner is well-trained to avoid this risk.
• Numbness or Altered Sensation: Some people report a feeling of numbness or tingling in the treated areas after the procedure. This is usually temporary, but in some cases, it can last for months.

When to Avoid Filler Injections

Before considering dermal fillers, it’s essential to be aware of any conditions or factors that could make the procedure unsuitable for you. Avoid filler injections if:

1.   Your Skin is Inflamed

If you have skin conditions like rashes, active acne, or hives, it’s important to wait until your skin is clear before getting dermal fillers. Inflamed skin is more prone to irritation, which can cause complications during or after the procedure.

2.   Allergies to Filler Ingredients

Always check the ingredients in the filler product. If you’re allergic to any of the substances in the filler, it’s best to avoid treatment. Your healthcare provider will discuss this with you during the consultation.

3.   Bleeding Disorders

If you have a condition that affects blood clotting, such as hemophilia or another bleeding disorder, fillers may not be a safe option. This is because fillers involve needles and the risk of bleeding could be higher.

4.   Pregnancy, Breastfeeding, or Under 18

The safety of dermal fillers hasn’t been studied in pregnant women, breastfeeding mothers, or individuals under the age of 18. It’s best to wait until you’re in a more suitable stage of life to consider this treatment.

5.   Tendency to Scar

If your skin is prone to scarring, like in cases where you develop keloids or excessive scar tissue, fillers may not be right for you. Scarring from the procedure could be more pronounced, leading to unwanted results.

Why Choosing the Right Practitioner Matters

When it comes to filler injections, choosing the right practitioner is key.  It’s like picking the right goalie for your favorite hockey team—getting the right person in the role can make all the difference between a smooth experience and something you’d rather forget.

So, our practitioners will work with you to create a personalized treatment plan that targets your specific concerns, whether it’s restoring volume in your cheeks or softening lines around your mouth. Plus, our aftercare support helps you recover smoothly, so you can see the results you’ve been hoping for.

Recovery Time After Getting a Filler Injection

The recovery time after getting filler injections is typically short, so you can get back to your daily routine in no time. Most people experience little to no downtime after their treatment. However, there are a few things to keep in mind.

After getting fillers, your healthcare provider might recommend avoiding strenuous activities—like lifting heavy weights or running a marathon—for 24 to 48 hours. This ensures that the filler has time to settle properly in your skin and produces the best results. It’s just like making sure your poutine is perfectly layered, right?

Everyone’s recovery can vary depending on the areas treated, the type of filler used, and individual factors like your health. If you tend to bruise or swell more easily, your practitioner may offer specific aftercare advice to help reduce these effects.  So, ensure that you share your medical history with your practitioner.

In most cases, you’ll be able to jump back into regular activities right after your appointment, but it’s always good to take it easy for a day or two.

How to Care for Your Skin After Filler Injections

Taking care of your skin after filler injections is key to ensuring you get the best results and a smooth recovery. While dermal fillers are minimally invasive, a little extra care goes a long way.

After your procedure, here’s what you should do:

• Cleanse Gently: Wash your face as usual, but avoid harsh scrubs or exfoliants for the first few days.
• Cool Compress: Apply a cool compress to the treated area to reduce swelling. Just don’t apply ice directly to your skin—wrap it in a cloth first!
• Use Arnica Cream: If you’re prone to bruising, arnica cream can help reduce the appearance of any bruises. For added coverage, feel free to use makeup after 24 hours.
• Avoid Strenuous Activity: Refrain from intense exercise for 24 to 48 hours after your treatment. It’s a good idea to take it easy to give your skin time to settle.
• Sleep Smart: If you’ve had filler in your face, try to sleep on your back for the first few nights to avoid putting pressure on the treated area.

When to Call a Doctor

Although serious complications after dermal fillers are rare, it’s important to know when to seek help. If you experience any of the following symptoms, don’t hesitate to contact your healthcare provider:

• Excessive Swelling or Pain: Mild swelling is normal, but if it becomes extreme or painful, contact your doctor.
• Signs of Infection: If the injection site becomes red, hot, or swollen with pus, it could be a sign of infection.
• Difficulty Breathing or Swelling of the Face: In rare cases, fillers can trigger an allergic reaction. If you have trouble breathing or notice swelling in your face, seek emergency help immediately.
• Unusual Bruising: While some bruising is expected, if you notice large or rapidly spreading bruises, it could indicate a more serious issue.

Bottomline

Filler injections are a popular and fast way to enhance facial features, reduce wrinkles, and restore volume lost with age. However, like any cosmetic procedure, they come with potential side effects—ranging from mild redness and swelling to more serious complications in rare cases.

It’s essential to choose an experienced and qualified practitioner, like those at PADRA Clinic, to ensure safe and personalized treatment. By working with experts, you can achieve natural-looking results with minimal downtime and proper aftercare.
