How to choose
an injector.
The questions worth asking.
The injectable aesthetics industry in Canada is largely unregulated at the point of delivery. In Ontario, a wide range of practitioners can legally perform injections — physicians, nurses, and in some contexts other regulated health professionals — under varying levels of oversight. This is not inherently a problem. There are excellent injectors across all of those credential categories, and poor ones in all of them too.
What this means practically is that the credential alone does not tell you much. The questions worth asking go deeper than the letters after someone's name — and most patients do not know what they are.
This guide is an attempt to make that easier. It is written from the perspective of someone who has been on the other side of this conversation for 16 years. These are the things I would want to know if I were sitting in the patient's chair.
"The most important thing an injector can tell you is what they will not do, and why. Restraint is a clinical skill. A practitioner who is enthusiastic about every treatment you bring to them is not exercising it."
The questions worth asking
Red flags to watch for
No consultation before treatment — or a consultation that is immediately followed by a sales pitch for the maximum number of treatments.
Before-and-after photos that all show dramatic, highly visible results. Natural outcomes are harder to photograph and less frequently shared — but they are the ones worth having.
No hyaluronidase on site. This is a basic safety requirement for any clinic performing HA filler injections. If they do not stock it, walk out.
Injector who agrees with everything you suggest. Clinical expertise sometimes means saying no, or redirecting to a different approach. Unconditional agreement is not patient-centred care — it is avoiding a difficult conversation.
Pricing that seems too low to be credible. The cost of quality product, appropriate training, and a safe clinical environment is real. Injectors who significantly undercut market rates are usually cutting something — sometimes safety.
Heavy reliance on social media before-and-afters as the primary credential. Instagram is a marketing channel, not a portfolio review. Filters, lighting, and selective posting make it a poor proxy for consistent clinical quality.
Good signs to look for
The injector tells you what they would not do at this appointment — and has a clear clinical reason for it.
The clinic has a clear complication protocol and stocks hyaluronidase on site.
The treatment plan recommended is specific to your face and your goals — not a standard menu of treatments applied regardless of presentation.
The injector recommends starting conservatively and reviewing — rather than recommending the maximum amount at the first appointment.
The injector has a clear philosophy about natural results and can articulate what that means technically — not just as a marketing claim.
You left the consultation feeling informed rather than sold to — and with a realistic picture of what to expect and when.
A note on credentials in Ontario
In Ontario, aesthetic injections can be legally performed by physicians, registered nurses (RNs), and nurse practitioners (NPs) among others, under varying scopes of practice. Physicians can inject independently. RNs and NPs typically require a physician medical director and operate under a delegation or collaborative arrangement.
This means that the credential itself tells you less than you might expect about the quality of care you will receive. A physician with minimal aesthetic training and no complication management protocol is objectively less safe than an experienced RN with 10 years of injection experience, appropriate oversight, and hyaluronidase on site.
The questions that matter are: how much experience does this person have with this specific type of treatment, do they have appropriate safety protocols in place, and do they have a clinical philosophy that aligns with what you are trying to achieve?
Frequently asked questions
Is it better to see a physician or a nurse for injections?
The credential type matters less than the specific practitioner's experience, training, and clinical approach. There are outstanding nurse injectors and mediocre physician injectors, and vice versa. The questions in this guide apply regardless of credential — use them to assess the specific person in front of you, not their title.
How do I know if a before-and-after photo is real?
You often cannot verify with certainty. What you can do is look for consistency across multiple photos — consistent lighting, consistent patient types, results that look natural rather than uniformly dramatic. You can also ask to speak with a past patient, or look for reviews that describe the experience in specific clinical terms rather than just "amazing results."
What should I do if I have a complication after treatment?
Contact your injector immediately. Any new pain, skin colour change, or vision change after a filler treatment should be treated as a potential emergency — these can be signs of vascular compromise and require immediate reversal with hyaluronidase. A reputable clinic will have a protocol for this and will be reachable after hours for urgent concerns.
Is it safe to get injections from a clinic I found on social media?
Social media presence is not a safety indicator in either direction. A clinic with a large Instagram following can be excellent or dangerous. Apply the same criteria you would to any clinic — ask about credentials, safety protocols, complication management, and look for the signs described in this guide. The number of followers is not one of them.
