No face is perfectly symmetrical, and small differences between the two sides are part of what makes each face unique. Sometimes, however, asymmetry becomes more visible because of genetics, ageing, an injury, dental changes or habits such as always chewing or sleeping on the same side. Dermal fillers offer a minimally invasive way to rebalance the face.

Understanding Facial Asymmetry

Facial asymmetry can involve volume (one cheek fuller than the other), shape (a lip line higher on one side) or structure (a chin or jaw that deviates slightly). It can be:

Congenital, present from birth.
Acquired, linked to ageing, weight loss, dental work, trauma or certain medical conditions.
Functional, influenced by muscle habits.

What Dermal Fillers Are and How They Help

Dermal fillers are injectable gels, most often made of hyaluronic acid (HA), that add volume and support. To correct asymmetry, the injector adds product in a targeted way to the side or area that needs it, until both sides look more balanced. Because HA can be dissolved if necessary, it is the first choice for most asymmetry corrections. In Canada, HA ranges include JUVÉDERM®, RESTYLANE®, BELOTERO®, TEOSYAL® and REVANESSE®.

Areas Commonly Treated for Asymmetry

Lips, to even out the shape or volume of the upper and lower lip.
Cheeks, to rebalance volume between the two sides.
Chin and jawline, to correct slight deviations.
Temples and tear troughs, where volume loss can be uneven.
Nose, in some cases, to correct minor irregularities without surgery.

How the Procedure Works

A consultation to analyze the face, often with photos from several angles.
A personalized plan indicating the areas, products and volumes.
Skin disinfection and, if needed, a numbing cream or a product containing lidocaine.
Precise injections, with regular checks of the balance between the two sides.
A follow-up appointment after about two weeks to assess the result and adjust if needed.

What to Expect From the Results

Results are visible immediately, but swelling can temporarily make one side look fuller. The final result is assessed after about two weeks. HA fillers generally last from several months to over a year depending on the product and area. The goal is better balance, not perfect symmetry, which would look unnatural.

Choosing a Qualified Provider

Asymmetry correction requires a careful eye and an excellent understanding of facial anatomy. Choose an injector with experience in this type of treatment. In Canada, who may inject fillers depends on the province and the professional college. See our questions to ask during a filler consultation.

Preparing for Your Appointment

Avoid alcohol and, if your physician agrees, supplements that increase bleeding in the days before. Arrive with clean skin and share your medical history. Our preparation guide gives the details.

Comparing Fillers With Other Asymmetry Treatments

Neuromodulators can help when asymmetry is caused by muscle activity.
Biostimulators such as SCULPTRA® gradually improve volume and skin quality, but cannot be dissolved.
Surgery may be necessary for significant structural asymmetry.
Orthodontic or dental treatment can correct asymmetry related to the bite.

Common Questions About This Topic

How long do dermal fillers for asymmetry last?

Generally from several months to over a year, depending on the product, the area and the patient’s metabolism.

Is one treatment enough to fix facial asymmetry?

Often, but a touch-up may be needed after the follow-up appointment to refine the balance.

Do fillers feel different on each side of the face?

They should not, once swelling has resolved. A slight difference in sensation may be felt during the first days, especially if more product was used on one side.

Can fillers help with scars or uneven texture?

Some depressed scars can be improved with fillers. Texture irregularities often respond better to skinboosters or skin treatments. See our skinboosters category.

What is the best way to prepare for treatment?

Avoid alcohol and blood-thinning supplements beforehand if your physician agrees, arrive with clean skin and discuss your goals clearly with your injector.

Is it safe to buy dermal fillers online?

Not for the public. Dermal fillers are intended for healthcare professionals and should be obtained through legitimate supply channels, such as Kinami Health for licensed clinics. Products sold to the public online may be counterfeit or contaminated.
