Lip filler is a non-surgical injectable treatment that adds volume, refines shape, and enhances the natural beauty of your lips. Filler is made from hyaluronic acid gel, which draws water into the tissues to add volume and shape. The amount of filler needed depends on your goals and anatomy, usually starting with 0.5 to 1 syringe of filler. Results usually last 9–12 months, with repeat treatments either at that interval or whenever you'd like additional enhancement.
At Park, all lip filler treatments are performed by licensed physicians and nurses with advanced training in facial anatomy, overseen by Dr. Shoghi Nikoo, CCFP at our clinic on Ossington in Toronto. Every treatment begins with a consultation so we can develop a treatment plan to restore volume, define shape, and enhance your lips in a way that looks balanced, soft, and completely you.

How to get started
Book a consultation with our team to assess your lips and goals. If filler is right for you, we can treat it the same day if pre-booked.

What does lip filler do?
Volume restoration
As we age, the lips naturally lose collagen, fat, and elasticity, leading to a thinner, deflated appearance. Lip filler restores that lost volume, bringing back a fuller, softer look that still reads as you.
Lip shape enhancement
Beyond volume, filler can refine the shape and symmetry of the lips, define the Cupid’s bow, and balance proportions. At Park, we tailor all of this to your unique facial structure.
Corrective of previous filler
If you’ve had lip filler elsewhere and are unhappy with the results, we can dissolve and correct poor placement, unevenness, or overly filled lips to restore a more natural and balanced look.
Balancing asymmetry
If one side of your lip is fuller than the other, or your top and bottom lips are out of proportion, lip filler can subtly rebalance your shape.
Most common questions
-
Lip filler is a hyaluronic acid gel that’s specially manufactured to add volume and structure while moving and flexing with lip movements to maintain a natural appearance. Hyaluronic acid is a hydrophilic sugar-based molecule, meaning it draws in water to create volume. It naturally integrates with the tissues it’s injected into, making it essentially undetectable in most cases. Because hyaluronic acid is naturally produced by the body, the body naturally breaks it down over time. We can also dissolve it at any time, making it the safest way to add volume to the face. At Park we use the Teosyal line by Teoxane, a premium brand based in Switzerland that uses advanced crosslinking to maximize natural flex with facial movements and longevity of results.
-
Most clients need 1–2 sessions to reach their desired result, depending on how much of a change they’re looking for. We usually recommend incremental changes over multiple visits instead of drastic changes in one visit to ensure natural-looking results even with more significant changes.
To maintain, we recommend touch-ups every 6 to 12 months, depending on the product used, your metabolism, and your goals. People who are more active, who sing professionally, or who smoke, usually metabolise filler faster than average.
At Park, we believe in keeping your results natural, balanced, and in harmony with your features. Sometimes, that means periodically dissolving old filler to minimize or correct migration and ensure your filler continues to complement your natural facial structure. We may require dissolving filler placed at other clinics before we inject more; adding filler when we don’t know what’s already there risks unintended excess volume, migration, and otherwise suboptimal results. Your provider will assess your history and how things look to decide whether dissolving is necessary.
-
Lip filler at Park is priced by treatment plan, not by syringe. During your consultation, we’ll assess your anatomy and goals, and recommend what we believe will give you the best result. The minimum amount that could technically work often leads to disappointing results despite hundreds of dollars spent. Our goal is a result you’ll love, not a number on an invoice.
Wherever in Toronto you get your treatment, pricing reflects the type and amount of product used, the complexity of your treatment, and the expertise of your injector.
Lip filler starts at $420+tax. -
Lip filler can be a great way to enhance your natural features or rejuvenate volume lost over time, and can be as subtle or substantial as you want. But some people aren’t good candidates for lip filler:
Anyone who is pregnant or breastfeeding should avoid filler.
People with a history of cold sores can get the treatment but should consider getting a prescription for prophylactic antivirals to use before their treatment.
If you have a bleeding disorder or are on anticoagulants, mention this during your initial consultation so we can ensure the treatment is safe for you.
If your lips are extremely thin, lip filler may not be safe or effective; we’ll be able to tell you what we think at your consultation.
Lip filler also does come with a very rare but not impossible chance of tissue damage if the filler blocks an artery or vein. Our providers are trained to avoid and manage this complication, and we keep everything needed to treat it on hand at all times (see FAQ below). Clients who are extremely risk averse may choose to stick to lip flips instead.
When will I see results?
You will see a change immediately, though much of what you see in the hours and days after the treatment are due to swelling. As the swelling subsides, you’ll be able to see what the results really look like. We always have clients come back at the two-week mark to review your results.
What happens at a lip filler appointment?
What do I do before my lip filler appointment?
Avoid NSAIDs like Advil, ibuprofen, or Aleve and alcohol 24 hours before your appointment to help minimize bruising and swelling. Arriving well-hydrated will improve your results because lip filler is made of hyaluronic acid, which works by attracting water molecules to build volume; being well hydrated will also help reduce discomfort, swelling, and bruising risk.
If you're planning to leave Toronto between your treatment and your follow-up assessment, please let us know — we won't be able to treat you without being sure you're available for any necessary post-care that may be required between visits and may need to reschedule your treatment.
What happens during the appointment?
Your appointment starts with a personalized consultation to discuss your goals and assess your lip anatomy. We’ll recommend the best filler type and amount for you. We’ll cleanse and numb the area with a BLT numbing cream that includes bupivacaine, lidocaine, and tetracaine to keep you comfortable. After cleansing and numbing the area, treatment typically takes about 20 minutes, and you’ll see immediate results.
What is the downtime like after lip filler treatment?
Immediately after, expect swelling that will last 48-72h. Bruising is also possible with all filler types, and areas closer to the surface or with more vasculature, like the tear troughs, are more prone to bruising. Most bruising resolves in about a week.
For the 2-4 weeks after treatment, you’ll probably be able to feel the filler itself, which will feel like little bumps or nodules. This is normal and will become less noticeable with time. Some people are able to feel the filler for several months after, which is also normal as long as it’s relatively mild, not visible, and not painful.
To reduce your downtime: stay upright for at least 3 hours post-treatment, and avoid rubbing the treated areas. Avoid alcohol, exercise, sex, saunas, and other forms of extreme heat for 24 hours. Wait at least 24 hours before resuming NSAIDs (like Advil, ibuprofen, or naproxen) or blood-thinning supplements unless prescribed.
Frequently Asked Questions
-
Lip filler is a hyaluronic acid-based injectable treatment that adds volume, enhances definition, and improves hydration in the lips.
-
Like any medical procedure, fillers carry some risk including the rare but serious possibility of interrupting blood flow if filler enters a blood vessel. This can lead to complications such as tissue damage or in very rare cases vision loss. Our providers are carefully trained on identifying early signs of complications and acting immediately. We also have a medical director on site or immediately available by video call at all times. We keep hyaluronidase - the enzyme used to dissolve hyaluronic acid - on hand at all times, so we’re always prepared to intervene immediately. Our protocol also includes a series of interventions to improve collateral blood flow, which is important to further reduce the risk of tissue damage.
-
Yes. We tailor every treatment to your unique facial structure and goals, ensuring your lips look soft, balanced, and never overdone. The Teosyal line of fillers we use is specially designed to move and flex with your lips so you won’t end up with stiff or duck-like lips.
-
Discomfort is minimal. We use a topical numbing cream that includes bupivacaine, lidocaine, and tetracaine before your injection when possible. Teosyal fillers used at Park also contain lidocaine to ease discomfort after the procedure.
-
Lip filler typically lasts 9-12 months, depending on the amount and type of filler that was injected. More filler will take longer to be metabolized by the body, and newer technologies like those used in Teosyal’s manufacturing process make filler last longer than older fillers did. We recommend an assessment 9 months after your initial injection to keep your look fresh, and you’re welcome to return sooner if you’d like to add more volume.
-
Migration, especially in the lip, is common after multiple treatments. Over time, the body breaks down the filler, but it doesn’t always completely reabsorb it. The smaller fragments of filler that are left behind are more mobile than the larger molecules that were originally injected, meaning they can move outside of the intended treatment area. Mobile areas, like the lip, are more likely to see migration than other areas of the face. Injecting more filler in previously-treated lips may also push the old filler outside the intended treatment area. This is most common after three or more sessions, which is why we recommend dissolving the filler and starting with new product after three treatments.
-
Most clients get 0.5-1ml, or a half or ‘mini’ syringe to a full syringe, for a subtle enhancement in their first session, and decide whether they would like more at their post-treatment assessment. The specific amount of filler depends on your goals and your provider’s assessment of your anatomy. Clients who want more dramatic volume will need more filler, which we usually do over sequential visits to ensure you never look overdone.
-
The most important thing to know is whether your provider is capable and prepared to manage a complication; safety is the most important thing, and it’s important that you trust your injector.
Getting lip filler can be a big step. It’s normal to have moderate swelling for 48h following your appointment. The lips will likely feel tight and achy, which is also normal. Bruising is common and improves within a week. Significant pain, especially if it’s localized in one place or getting progressively worse, is something that your provider should assess.
For your first time getting filler, we recommend starting with a conservative amount of filler, 0.5 to 1ml for most people, and building on that as desired. We always have people come back at two weeks to assess results, ensure you’re complication-free, and make any additions or tweaks you’re interested in.
-
The single most important thing in a clinic is its emergency preparedness. The best clinics for lip filler will be the ones that are prepared to treat complications, that have specific, evidence-based protocols available in the treatment rooms, and that have everything needed to treat an occlusion in stock at all times.
Having a doctor or nurse practitioner on site will further ensure your safety, because they will be more available to help with complications than a clinic or provider who only has virtual access to their medical director. Clinics that have all of these will be well-practiced in providing injections, so you know that you’ll be getting the safest treatment and best outcomes possible.
Being in close proximity to your clinic will also be important if you have a complication in the days following your treatment; being able to get to your provider quickly will help reduce the risk of a poor outcome. Park Medical Aesthetics is a great option if you live in Dundas West, Queen West, Liberty Village or Roncesvalles.
-
Hyaluronic acid filler is reversible. If needed, we can dissolve the product using an enzyme called hyaluronidase. It’s quite rare for us to do this for treatments done at Park, but patients across Toronto come to Park for corrective work after lip filler that was injected elsewhere.
-
We use the Teosyal line by Teoxane at Park Medical Aesthetics. Over his aesthetics career Dr. Shoghi has used filler products from Restylane, Juvederm, and Revanesse, and has found that Teosyal produces the most natural looking results with the injection techniques used at Park. That said, provider skill and knowledge is much more important than the specific product used; always choose a provider who is licensed and experienced in lip filler injection and complication management.
-
Lip filler uses hyaluronic acid to add volume and structure. A lip flip treatment uses neurotoxin to relax the orbicularis oris muscle, causing slight eversion and the illusion of a larger lip without actually changing anatomical volume or structure. Many patients benefit from both, and your provider can help you design a treatment plan to match your goals.
-
Yes, though depending on how the lips look, we may recommend dissolving your previous filler before adding more. At Park Medical Aesthetics we believe in keeping your results natural, balanced, and in harmony with your features, and sometimes that means dissolving old filler to minimize or correct migration.
Adding filler when we don’t know what’s already there risks unintended excess volume, migration, nodules and otherwise suboptimal results. Your provider will assess your history and how things look to decide whether dissolving is necessary.
-
Lip filler needs very little in terms of up-keep between treatments. Because hyaluronic acid works by attracting water molecules to create volume, being well hydrated at and for the days following your appointment will improve your results; it will also help with discomfort, bruising, and swelling. Pairing the right skincare can also improve your results:
Skinceuticals AOX Lip Repair: using this once in the morning will protect your lips from oxidative stressors, protecting protein function and overall health and appearance of the lips.
Skinceuticals HA Intensifier Multi-glycan serum, can help optimize and prolong your results by maintaining the lips’ hyaluronic acid and moisture balance – especially because filler is made with hyaluronic acid.
