If you’ve been standing in front of the mirror wondering whether you need Botox or filler, you’re not alone — it’s one of the most common points of confusion for people considering their first aesthetic treatment. The short answer: they solve different problems, and the “right” one depends entirely on what you’re actually seeing in the mirror, not on which one you’ve heard of more.
The Core Difference
Botox (botulinum toxin) works on muscles. It temporarily reduces the activity of specific facial muscles, which softens the lines that form from repeated movement — forehead lines, frown lines between the brows, crow’s feet around the eyes. It doesn’t add anything to your face. It just reduces the muscle pull that’s creating the line.
Dermal fillers work on volume. They’re placed beneath the skin to restore or add fullness in areas that have lost volume, or to contour areas like the lips, cheeks, or jawline. Nothing about how you move your face changes — filler addresses structure, not motion.
A simple way to think about it: if a line only shows up when you make an expression (frowning, squinting, raising your eyebrows), that’s usually a Botox concern. If an area looks hollow, flattened, or has lost definition even at rest, that’s usually a filler concern. Many people eventually need both, in different areas, because most faces show both kinds of change over time.
Where Each Is Commonly Used
Botox: forehead lines, frown lines (the “11s” between the brows), crow’s feet, and — separately from wrinkles entirely — hyperhidrosis (excessive sweating), most often in the underarms.
Dermal fillers: lips, cheeks, under-eye hollows (tear troughs), nasolabial folds (smile lines), marionette lines, jawline, chin, and even the backs of the hands.

“Which Do I Need First?”
This is the question people get stuck on, and honestly, it’s the wrong question to start with. The better starting point isn’t “Botox or filler” — it’s “what specifically bothers me, and does it show up when I move my face, or all the time?” That answer points you toward the right category before you’ve even had a consultation.
If you genuinely can’t tell — which is common, especially the first time — that’s exactly what a consultation is for. Guessing based on what a friend got, or what showed up in your Instagram feed, is how people end up treating the wrong thing.
A Real Concern Worth Addressing Directly: “What If I Overdo It?”
This comes up constantly, and for good reason — it’s a legitimate worry. The pattern people describe isn’t usually one dramatic bad decision. It’s small, incremental additions over time that each seemed reasonable in isolation, until the cumulative result looks different than intended. You notice it in yourself less than others notice it in you, simply because you’re seeing gradual change day to day rather than all at once.
The practical takeaway: conservative, individualized dosing and a provider willing to say “let’s wait and see” rather than “let’s add more” matters more than almost anything else in this decision. This is also part of why a consultation-first approach — assessing before recommending, rather than recommending before assessing — is the right structure for this kind of treatment, not just a nice-to-have.
Is It Reversible?
Worth knowing if you’re nervous about committing: most hyaluronic acid dermal fillers can be dissolved if you’re unhappy with the result. Botox isn’t reversible in that same sense, but it’s temporary — it wears off gradually over months, so an outcome you don’t love isn’t permanent either.
Credentials Matter More Than Price
If you take one practical thing from this post: don’t choose based on the cheapest price you can find. Both treatments require someone who understands facial anatomy in depth, and a very low price is one of the more reliable red flags for an under-qualified injector or an unsafe product source. Ask directly about your provider’s training and experience before booking anywhere — not just at MJ Aesthetics.
At MJ Aesthetics, Mehran Javidan, IMG, brings approximately 20 years of hands-on experience in medical aesthetics, and treatment is provided under physician delegation at Green Clinic East in North York, in accordance with Ontario’s Regulated Health Professions Act — Mehran is an International Medical Graduate who is not currently registered as a physician with the College of Physicians and Surgeons of Ontario, and treatments are provided within that clearly defined scope.
Can They Be Combined?
Often, yes. It’s common to treat forehead and frown lines with Botox while addressing cheek or lip volume with filler in the same overall plan. Whether that combination makes sense for you specifically is something to work through in a consultation, not something to assume from a list.
