Botox or Filler? A Physician's Guide to Choosing the Right Treatment

When it comes to non-surgical facial rejuvenation, Botox® and dermal fillers are two of the most effective and widely requested treatments. While both are injectable and deliver noticeable anti-aging results, they work in very different ways and are used to treat different concerns.
At MD Skin Lab in Toronto, our physician-led team carefully evaluates your facial anatomy, muscle activity, and volume loss before recommending the right treatment (or combination) for your goals. In this guide, we’ll break down the key differences between Botox® and dermal fillers, which areas each one treats best, and how to decide what’s right for you.

What’s the Difference Between Botox® and Fillers?
Before exploring specific treatment areas, it’s important to understand how these two products work:
-
Botox® (and other neuromodulators like Dysport®, Xeomin®, and Nuceiva®) temporarily relax the muscles that cause dynamic wrinkles—those formed from repeated facial expressions like frowning, squinting, or raising your eyebrows.
-
Dermal fillers (such as Teosyal®, Juvederm® and Restylane®) are gel-like substances, typically made from hyaluronic acid, that restore lost volume, smooth static wrinkles, and enhance facial contours.
In short:
-
Botox® softens movement-based lines
-
Fillers add volume and structure
What Areas Are Best Treated with Botox®?

Botox® is most effective in areas where wrinkles are caused by repetitive muscle movements. These tend to be in the upper face, but they have growing uses in the lower face and neck when performed by an experienced injector, like our physician injectors in Toronto.
1. Forehead Lines
Horizontal forehead lines form when you raise your eyebrows. Botox® relaxes these muscles to prevent creasing and give a smoother appearance.
2. Frown Lines (Glabellar Lines / "11s")
These vertical lines between the brows appear when you squint or frown. Treating them with Botox® helps soften a tense or angry look.
3. Crow’s Feet
Botox® is highly effective for the fine lines around the eyes caused by smiling or squinting.
4. Brow Lift
Strategic Botox® placement can gently elevate the brows, creating a more lifted and refreshed look.
5. Bunny Lines
Small wrinkles on the sides of the nose when you smile or scrunch your face.
6. Masseter Reduction (Jaw Slimming)
Botox® can be used to soften the masseter muscles for facial slimming or to help manage jaw clenching and TMJ symptoms.
7. Lip Flip
Botox® injected into the muscles above the upper lip helps create the appearance of a fuller lip without adding volume.
8. Chin Dimpling
Botox® can smooth out dimpling or a “pebble chin” effect caused by overactive muscles.
9. Neck Bands (Platysmal Bands)
Botox® helps reduce visible vertical neck bands for a smoother neck profile. You can book your Botox in Toronto here. Book an appointment with MD Skin Lab

What Areas Are Best Treated with Dermal Fillers?
Dermal fillers are ideal for restoring volume loss, enhancing facial contours, and softening static lines visible even when the face is resting. They’re incredibly versatile and can be used on the face and body. All dermal fillers are administered by physician injectors at MD Skin Lab.
1. Cheeks
One of the most popular areas for filler, the cheeks, tends to lose volume with age. Filler restores youthful fullness and supports the midface.
2. Under-Eyes (Tear Troughs)
Hollowing under the eyes can make you look tired. Carefully placed filler can reduce shadowing and create a brighter appearance.
3. Nasolabial Folds
These deep lines running from the nose to the mouth are softened with filler for a smoother transition between facial features.
4. Marionette Lines
Lines that extend from the corners of the mouth downward can be softened and lifted using filler.
5. Lips
Fillers add volume, define shape, and improve symmetry in the lips, whether you want a natural or fuller look.
6. Jawline
Filler can contour and define the jawline, improving the appearance of jowls or soft tissue sagging.
7. Chin
Chin filler can project and shape the chin, enhancing facial balance and profile.
8. Temples
Filler in the temples helps correct hollowing and improve overall facial harmony.
9. Hands
Fillers can also be used to rejuvenate aging hands by restoring volume and reducing visible veins and tendons.
10. Nose
Often called a non-surgical rhinoplasty, nose filler can smooth bumps, lift a drooping tip, or create a more balanced nasal contour without surgery.

Can Botox® and Fillers Be Used Together?
Absolutely! In fact, combining Botox® and dermal fillers is one of the most effective ways to achieve natural, balanced, and long-lasting facial rejuvenation. This approach—often referred to as a “liquid facelift”—addresses both dynamic wrinkles and volume loss in one cohesive treatment plan.
At MD Skin Lab, we frequently use combination therapy to:
-
Smooth the upper face with Botox®
-
Restore midface volume with cheek filler
-
Define the jawline and chin
-
Soften nasolabial folds or under-eye hollows
-
Enhance lips and balance proportions
Our team ensures all treatments are customized based on facial structure, skin quality, and your long-term aesthetic goals. We recommend booking an appointment so our physician injectors can build a tailored plan for you, featuring one or both treatments.
