How Effective Are Hyaluronic Acid Fillers?
Hyaluronic acid (HA) is a Health Canada–licensed non-surgical filler that can help improve wrinkles, shape facial contours, and boost skin hydration, with results lasting months to a few years, suitable for adults under professional medical guidance.
Key Takeaways
- Hyaluronic acid, the main component of these fillers, occurs naturally in the body and is gradually metabolized after injection, giving it a degree of reversibility.
- Common filling sites include the lips, tear troughs, cheeks, nasal bridge, chin, and temples, with results typically lasting 6 to 18 months.
- Aftercare: gentle cold compresses (no heat) within 48 hours, no touching or makeup on the site for 24 hours, and no smoking or alcohol for one week.
- Dr. Dan Xu (MD, CCFP) recommends that Asian patients first assess their structural (bone-based) contouring needs before deciding on fillers or device treatments.
- In the Toronto/Markham area, ID Cosmetic Clinic offers personalized hyaluronic acid filler plans based on individual facial structure, plus a free consultation appointment.
Direct Answer
Hyaluronic acid (HA) is a polysaccharide that occurs naturally in the body's connective tissue and skin, with a strong water-binding capacity. When used as a dermal filler, it is injected under the skin as a gel that both physically supports tissue and retains moisture, helping to restore volume, refine contours, and reduce wrinkles. Because HA closely resembles substances already present in the body, the risk of allergic reaction is relatively low, and it is gradually metabolized after injection, giving it a degree of reversibility. Common injection sites include the lips, cheeks, tear troughs, nasal bridge, chin, temples, and nasolabial folds; how long results last varies with the product, volume, and individual metabolism, typically between 6 and 18 months. In the Markham and Toronto area, ID Cosmetic Clinic is led by Dr. Dan Xu (MD, CCFP), and the clinic uses Health Canada–licensed brand-name fillers including Juvéderm, Teosyal, and Restylane. Dr. Xu holds a Canadian medical doctorate and focuses on blending Eastern and Western aesthetic ideals, tailoring plans to Asian facial proportions and bone structure. Dr. Xu notes that for Asian facial types, structural (bone-based) contouring often delivers greater overall lifting and a visually slimmer face than surface filling alone, and recommends a thorough assessment by a qualified physician before treatment to determine the priority and combination of device treatments and injections.

Hyaluronic acid Toronto
Hyaluronic acid can help smooth wrinkles, shape the ideal facial contour, and counter the effects of aging. In Toronto, Canada, hyaluronic acid fillers are approved non-surgical products whose results can last for an extended period. Common injection areas include the lips, cheeks, under-eyes, nose, chin, and jawline.
The fillers used at ID Cosmetic Clinic are among the top products available in Canada — for example, the “Hermès” of hyaluronic acid, Juvéderm. In addition, we also use Teosyal, Restylane, and others.
The main component of these fillers is hyaluronic acid, a substance that naturally occurs in the human body, which means there is a lower risk of the filler being broken down abnormally by the body over time. These products are authorized for sale by Health Canada and are considered safe.
Main Uses of Hyaluronic Acid:
The main benefits and functions of hyaluronic acid are as follows:
Benefit One: Skincare and Beauty
Hyaluronic acid has excellent moisturizing properties, restoring and improving the skin’s hydration and elasticity, making the skin look plumper and more radiant.
Benefit Two: Facial Shaping
Hyaluronic acid can be used for facial filling to help create ideal facial lines and fullness. Common filling areas include the chin, nose, temples, tear troughs, cheeks (apple muscles), nasal root, nasolabial folds, and lips.
Benefit Three: Reducing Wrinkles
Hyaluronic acid can combat deep wrinkles formed by reduced collagen and a lack of elastic fibers, such as nasolabial folds and crow’s feet — wrinkles that ordinary skincare products struggle to improve.
Benefit Four: Facial Volumizing
In addition to the above benefits, hyaluronic acid is also used for other facial volumizing procedures. For example:
Lip Enhancement: Using hyaluronic acid to add volume to the lips, making them fuller and plumper.
Cheek (Apple Muscle) Filling: With age, the cheek fat pad over the cheekbone gradually sags, blurring the facial contour. Hyaluronic acid can fill this area, making it fuller, reducing the appearance of nasolabial folds, and giving the face a more youthful look.
Temple Filling: Because sunken temples can create an unbalanced facial line, hyaluronic acid can adjust and balance the facial contour while lifting the cheeks, making them firmer and more youthful.
Aftercare Following Hyaluronic Acid Injections
- Heat application is not recommended after injection, but gentle cold compresses can be applied within 48 hours — avoid pressing on the injected area while doing so.
- For the first 4 hours after injection, keep the body upright, and lie flat when sleeping at night to prevent the filler from shifting.
- Within 24 hours after injection, do not touch the injection site, avoid washing your face and applying makeup, and keep the injection site free from infection.
- If you had lip enhancement, avoid touching your lips within 24 hours, be careful not to touch your lips while eating for a week, and avoid overly cold or hot foods.
- Do not smoke or drink alcohol within one week after injection.
Dr. Dan Xu’s Perspective on Hyaluronic Acid Fillers
Dr. Dan Xu, founder of ID Cosmetic Clinic in Toronto, believes that for Asian facial structures, bone-based (structural) contouring is more important than surface-level filling. Structural contouring can instantly lift the entire face and create the visual effect of a slimmer appearance. Therefore, before undergoing any device treatment or hyaluronic acid filling, please consult a qualified physician first to find the treatment plan best suited to your lifting, tightening, and facial structural shaping needs.
Everyone’s face is different. The decision of whether to first perform device-based contouring or structural liquid-lift shaping should be based on each person’s original facial proportions and the changing curves of their dynamic facial expressions.
