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.

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

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.
