The commonest regret is not too little. What an overtreated upper face actually looks like, why the dosing asymmetry only points one way, and what a well-judged first appointment should and should not do.

The most common regret we are asked to correct is not that somebody had too little. It is that a first appointment was dosed for a result the person had seen in a photograph, on a face that was not theirs, and then took three months to wear off.
Not the caricature. A genuinely overtreated upper face is subtler and stranger than the frozen forehead of a magazine article, and the tell is almost always a mismatch.
The forehead is smooth and entirely still while the lower face is fully animated, so the face reads as two people. Or the brows sit lower than they did, because the frontalis — the only muscle that lifts them — was treated too heavily and too low, and the eyelid platform looks crowded. Or the centre of the forehead is relaxed while the outer fibres are not, and the brow tails climb into a permanent arch. That last one is easy to correct and unmistakable once you have seen it.
There is also true eyelid ptosis, where product reaches the levator and the upper lid itself droops. It is uncommon, it is not the same thing as a heavy brow, and it does resolve — but it takes weeks, and drops only partly compensate in the meantime.
The version nobody photographs is the loss of signal. A face communicates agreement, concern and interest largely through the upper third. Remove all of it and people who know you will say you look well, and then ask, twice, whether you are annoyed with them.

Muscle mass varies more than people expect. Men typically need more. So do people who lift heavily, and so do some very expressive faces with no obvious marker at all. There is no reliable way to know where a particular frontalis or corrugator sits on that range before treating it once. Published dosing ranges are wide precisely because the response is.
The asymmetry that governs the decision is this: adding is easy and removing is impossible. If we are under-dosed at the two-week review, the correction takes five minutes and a few units. If we are over-dosed, there is nothing to be done except wait ten to fourteen weeks. That asymmetry only points one way, and it is the whole argument for starting at the lower end of the range on a face we have not treated before.
When you are ready
Reading is a good start. Forty-five minutes in the room is where we look at your face in good light, ask what you have already tried, and tell you what we actually think.

A neuromodulator begins working at day three to five and reaches full effect at about day fourteen. Judging the result before then is judging an incomplete process, which is why we book the review at two weeks and why we ask people not to form an opinion before it.
At that review we look at brow position at rest, the height and symmetry of the brow tails, whether the frown still recruits, how the outer eye behaves on a full smile, and whether the forehead has retained enough movement to look like a forehead. Then we adjust — usually a small addition, sometimes nothing at all. The appointment is included in the treatment, and skipping it is the most expensive saving available.
Most people return at twelve to sixteen weeks. Treating more often than every twelve weeks, or at consistently high doses, is associated with the development of neutralising antibodies. It remains uncommon with modern preparations, and the way to keep it uncommon is the smallest effective dose at the longest interval that holds — not a top-up every eight weeks because a line reappeared.
If a product has genuinely stopped working for someone who used to respond well, that is worth investigating properly rather than solving by doubling the dose.
A deep static line, visible at rest, will soften with treatment but will not disappear. It needs the muscle relaxed for months, and often resurfacing or a very small amount of product in the line itself. Promising erasure of an etched line is overpromising.
A brow that is already heavy, with hooding over the outer lid, can be made worse by forehead treatment. In that face the honest answer is sometimes a lighter dose confined to the frown and the outer eye, and sometimes a referral for an assessment of the lid itself.
Masseter treatment for jaw slimming works, takes eight to twelve weeks to become visible, needs repeating, and can change chewing comfort for the first few weeks. It is a reasonable treatment with real trade-offs rather than a contouring shortcut.
A lip flip uses very few units, lasts six to eight weeks rather than three months, and reliably makes drinking through a straw and pronouncing certain consonants briefly strange. Worth knowing before a wedding.
Cleansing, marking, then a series of injections that feel like brief pinpricks. Small raised blebs appear and settle within twenty minutes. Some people get a mild headache in the first day or two. Bruising is possible and more likely on blood thinners or fish oil. You will look exactly the same when you leave, which surprises people, and the change arrives quietly over the following week.
Then you stay upright for four hours, skip the gym and the sauna until tomorrow, do not massage the area, and wait.
A well-dosed first treatment does not read as a treatment. The frown softens, the face still moves, and the most common report is that nobody noticed anything in particular and several people said you looked rested. That is a boring objective and it is the correct one. Starting there leaves every option open; starting at the maximum does not.
