Risks and Side Effects of Dermal Fillers

Dermal fillers have become one of the most sought-after cosmetic treatments in Australia, offering non-surgical enhancement of facial features, especially the lips and cheeks. At LA Lips, we specialise in dermal fillers and other injectable treatments, and while the results can be transformative, it’s essential to understand that no cosmetic procedure is without risks.

Before you book an appointment, it’s important to educate yourself about the potential side effects and complications of dermal fillers. This guide will walk you through the most common and rare side effects, how to minimise your risks, and what to expect post-treatment.

Common Side Effects of Dermal Fillers

The most common side effects of dermal fillers are mild, temporary, and typically resolve within a few days. These can include:

Redness and Swelling

After treatment, it’s normal to experience some redness, swelling or puffiness around the injection site. This usually subsides within 24 to 48 hours. Cold compresses can help reduce swelling.

Bruising

Bruising is another common response to dermal fillers, particularly in areas with delicate skin such as the lips. Bruises can last from a few days up to a week depending on your body’s natural healing.

Tenderness or Discomfort

Some people feel mild pain, sensitivity or tenderness in the treated area. This can feel like a dull ache or pressure and usually fades quickly.

Lumps or Bumps

In some cases, small lumps or bumps may appear after treatment. These are often due to swelling or uneven filler placement and can often be massaged out by your injector or resolve on their own.

Less Common Side Effects

Although less frequent, the following side effects can occur and may require medical follow-up:

Allergic Reactions

While rare, some individuals may experience allergic reactions to filler ingredients, or the anaesthetic used in the product. Symptoms can include itching, rash or more generalised swelling. Always inform your injector of any known allergies before treatment.

Infection

Like any injection, there’s a risk of infection. Good hygiene, proper aftercare, and receiving treatment from a qualified professional greatly reduce this risk. If you notice redness, warmth, pus or increasing pain in the area, it’s important to seek medical attention.

Delayed Swelling or Nodules

Some people may experience inflammatory nodules or delayed swelling weeks or even months after treatment. This could be due to an immune response or biofilm (a bacterial presence around the filler). These cases may require additional treatment such as antibiotics, steroids or dissolving the filler.

Asymmetry

Mild asymmetry is common in the early stages after filler due to swelling or minor variations in anatomy. However, if it persists after healing, your practitioner may recommend a follow-up appointment to adjust or top up the filler.

Rare but Serious Complications

While rare, some risks associated with dermal fillers can be serious. It’s critical to be aware of these and choose a highly trained professional to minimise your chances of experiencing them.

Vascular Occlusion

This is one of the most serious risks associated with dermal fillers. Vascular occlusion occurs when filler is accidentally injected into or around a blood vessel, blocking blood flow. This can lead to tissue damage or necrosis if not treated promptly.

 

Signs of vascular occlusion included:

  • Sudden, severe pain at or near the injection site
  • White or blotchy skin
  • Discolouration or mottling
  • Coolness or numbness in the area

If any of these symptoms occur, it is a medical emergency. Your injector must be trained to recognise and treat vascular occlusion immediately using hyaluronidase (an enzyme that dissolves filler).

Blindness

Though extremely rare, blindness has occurred following dermal filler treatments when filler is injected into arteries supplying the eyes. This complication is more common when treating areas such as the nose, forehead and temples. While uncommon, it underscores the importance of choosing an experienced, medically trained injector.

How to Minimise the Risk

Choosing a reputable clinic and an experienced injector is your first line of defence against complications. Here’s what to consider:

✅ Do Your Research

Ensure the clinic is reputable and the products used are TGA-approved. Avoid deals or offers that seem too good to be true.

✅ Book a Consultation First

An in-depth consultation is essential. At LA Lips, we always take the time to assess your medical history, understand your goals, and discuss potential risks before proceeding. Want to know more about what happens in a consultation?

✅ Check Qualifications

Only receive dermal fillers from qualified professionals who are trained in anatomy and emergency protocols. Ask if they are experienced in managing complications like vascular occlusion.

✅ Follow Aftercare Instructions

Post-treatment care plays a vital role in your recovery. Avoid alcohol, excessive heat (like saunas), strenuous exercise and touching the area for at least 24 hours after treatment.

What If I Don’t Like the Results?

One of the advantages of hyaluronic acid fillers is that they are reversible. If you’re unhappy with your results, your injector can use hyaluronidase to dissolve the filler. However, it’s always better to start conservatively and build up rather than overfilling from the beginning.

Final Thoughts

Dermal fillers can deliver beautiful, natural-looking results when performed by a qualified professional. However, like all medical procedures, they come with potential risks and side effects. Being informed and choosing a reputable clinic with highly trained injectors is the best way to ensure your experience is safe and satisfying.

At LA Lips, we’re committed to delivering results that are both stunning and safe. We prioritise patient education, open communication and personalised care in every treatment.
