In short. Adding a small amount at a two-week review is predictable; waiting out an effect that has gone too far is not. That asymmetry should shape every plan.
Key points
- Choose a physician who offers the review as part of the plan rather than as an extra appointment.
- A two-week review is the mechanism that makes conservative treatment safe; without it, a conservative first plan is just an incomplete treatment.
Two errors are possible in any injectable plan: treating too little and treating too much. They are not symmetrical. Too little can be corrected at a review, in an appointment, with a predictable result. Too much cannot be corrected at all; it can only be waited out. That asymmetry should decide how the first plan is written.
Why over-treatment cannot be undone
There is no reliable way to reverse the effect of botulinum toxin once it has begun. Filler can be dissolved with an enzyme, but a muscle relaxant cannot be switched off. An over-treated area means weeks of a face that does not move as the patient expects, and in the case of a brow or eyelid change, weeks of an appearance that is difficult to ignore.
Why under-treatment is not indecision
A conservative first plan is not a smaller version of the same treatment; it is a plan with a second step built into it. The review at two weeks is the second step, and it is where the plan is refined using information that only exists after the first treatment: how your movement responded, whether the brow shifted, and how the result reads on your own face rather than in theory.
Add, do not subtract
Choose a physician who offers the review as part of the plan rather than as an extra appointment. A two-week review is the mechanism that makes conservative treatment safe; without it, a conservative first plan is just an incomplete treatment.
What patients actually want
Most patients who say they want the lines gone actually want to look less tired, less cross, or less old in photographs. A maximally relaxed face does not reliably deliver any of those, and it can deliver the opposite by removing the movement that makes a face read as alive. The useful consultation question is not how much can be treated but what the face should do afterwards.
Where a fuller plan is right
There are patients and faces for which a fuller plan is the correct one, and refusing to offer it would be its own kind of failure. The difference is that it should be chosen deliberately, with the risk of a brow or eyelid change discussed and the review arranged, rather than arrived at by treating everything that can be treated.
The same logic applies to combining treatments
Where filler is combined with a muscle relaxant, or where several areas are treated at once, the same principle applies with more force: fewer changes at a time make it possible to know what produced what. Where filler is used, the additional risk of vascular occlusion — a time-critical emergency that can cause skin loss and, rarely, vision loss — is part of the decision and should be discussed before the sequence is agreed.
Ask before you agree if
- No review appointment is planned, or the plan is described as final.
- Several areas are being treated at once on a first visit with no staged approach.
- Filler is being added without any discussion of vascular risk or how it would be managed.
Frequently asked questions
Why not just treat fully the first time?
Because a full plan leaves no room for correction. If the result is more than you wanted, the only available options are waiting and time, which can mean weeks of a face you did not choose. A conservative first plan keeps both directions open.
Will a conservative plan look unfinished after two weeks?
It depends on what was aimed for. A plan designed to preserve expression looks like a face with softened movement, not like an incomplete treatment. A plan that under-treats by accident is different, and that is what the review is for.
How much can be added at a review?
Usually a small amount, targeted at the area that responded less than expected. The review exists precisely so that the second step is small and predictable, which is only possible if the first step was not maximal.
Risks & Limitations
- Temporary brow or eyelid droop after treatment, which resolves as the effect wears off.
- Bruising, swelling or a brief headache at and after the injection sites.
- Asymmetry, or an unwanted change in expression, which may need review before it settles.
- All botulinum toxin results are temporary and maintenance treatment is required.
- Where filler is injected in the same session, vascular occlusion — a time-critical emergency that can cause skin loss and, rarely, vision loss — is an additional risk.
- No outcome can be guaranteed. Results vary with anatomy, movement pattern and healing.
When to Seek Care
- Difficulty breathing, difficulty swallowing or slurred speech after treatment — seek emergency care.
- Drooping eyelid, double vision, or weakness spreading beyond the treated area.
- Severe pain, or skin turning white, grey, mottled or dusky after a filler injection — a vascular emergency.
- Any change in vision — seek emergency care immediately.
- Fever, spreading redness, warmth or pus at an injection site.
