Three Common Ways to Ruin Your Botox (and How a Skilled Injector Avoids Them)

Anti-wrinkle injections have a reputation for being quick and simple, and in the right hands they are. A few tiny injections, ten minutes in the chair, and softer lines that still let your face move the way it should. The problem is that the treatment only looks effortless when the person holding the needle genuinely understands the muscles underneath. Get the placement or the dose wrong and the result can range from disappointing to distinctly odd.

In one of my recent clinic videos, I talked through the three mistakes I see most often when patients come to me unhappy with previous treatment elsewhere. None of them are exotic. They are everyday errors that come from treating the forehead as three separate boxes rather than one connected system, or from chasing a wrinkle-free look without respecting how the face actually moves.

This article unpacks those three mistakes in more detail, explains the anatomy behind each one, and sets out what a considered approach looks like. If you have ever left an appointment with heavy brows, a frozen smile or lines that barely budged, you will probably recognise at least one of them.

Why Botox Is About Balance, Not Just Freezing Muscles

The muscles of the upper face don't work in isolation. They pull against each other in a kind of tug of war. The frontalis, the broad sheet of muscle across your forehead, is the only muscle that lifts the brows upward. Almost everything else in the region, including the muscles that create your frown lines and the crow's feet around your eyes, pulls down or inward.

That balance is the whole game. When an injector treats one area too aggressively or too timidly, they don't just affect that spot. They change the relationship between the muscle they treated and all the muscles around it. This is why a badly judged treatment can leave you with a heavy brow or an uneven expression even when the individual injection points looked reasonable on paper.

I often remind my patients that good anti-wrinkle treatment is really an exercise in restraint and mapping. The aim is not to switch a muscle off completely. It is to soften the pull just enough that your skin creases less, while the face still moves naturally and the brows stay where they belong. Understanding that principle makes the three common mistakes much easier to see.

Mistake One: Treating the Frown Lines Too Softly

The frown lines, the vertical creases between the brows often called the elevens, are created mainly by the corrugator and procerus muscles. These are strong, deep muscles, and in many people they are surprisingly powerful. When someone concentrates, squints in the sun or feels irritated, these muscles draw the brows together and downward.

A frequent error is under-dosing this area. The injector places a little product, the patient sees a small change, and everyone assumes the job is done. The trouble is that the frown complex often needs a genuinely adequate dose to relax properly. If it is treated too softly, the muscles keep pulling the inner brow down, and that has knock-on effects across the rest of the upper face.

Why weak frown treatment undermines everything else

Because the frown muscles pull the brow down and the frontalis lifts it up, these two forces are constantly negotiating. If the frown muscles are only partly relaxed, they keep dragging on the inner brow. That can flatten the results elsewhere and leave the whole upper third of the face looking heavy or tired rather than refreshed. Patients sometimes describe it as their treatment simply not working, when in reality the frown area was the weak link the whole time.

An adequately treated frown complex does more than smooth the elevens. It takes tension out of the brow so the forehead sits more comfortably and the eyes look more open. My point in the video is that softening this area properly is what protects and supports the result across the rest of the face. Skimp here and the balance is off from the start.

Mistake Two: Overtreating the Forehead and Dropping the Brow

The second mistake is the mirror image of the first. Here the frontalis, the forehead muscle, is treated too strongly or the injections are placed too low down toward the brow. Because the frontalis is the only muscle lifting the brows, weakening it too much removes the very support that keeps them raised.

The result is a heavy, dropped brow. Patients describe eyelids that feel weighted, a forehead that won't move, and a sense that their eyes are harder to open, particularly first thing in the morning or when they are applying makeup and need to lift the lid. In more pronounced cases the brow visibly sits lower than before, which is the opposite of the fresh, lifted look most people are hoping for.

Where and how much matters more than people expect

Safe forehead treatment is about placement as much as dose. Injecting too low, too close to the brow, sacrifices the lift you rely on. A careful injector keeps forehead injections high enough to soften the horizontal lines while preserving the lower fibres of the frontalis that hold the brow up. They also balance the forehead against the frown and the outer brow so the muscles that lift and the muscles that pull down stay in proportion.

This is also why the forehead should rarely be treated in isolation. Relaxing the frontalis without adequately addressing the frown muscles that pull down is a classic recipe for a heavy brow, because you have weakened the lifter while leaving the depressors free to do their work. It is one of the clearest examples of why the upper face has to be assessed as a whole.

Mistake Three: Getting the Crow's Feet Wrong

The crow's feet are the fine lines that fan out from the outer corners of the eyes when you smile. They are created by the orbicularis oculi, the ring-shaped muscle that surrounds the eye. Treated well, softening these lines gives a rested, natural look while your smile stays warm and genuine.

The mistake here comes in two forms. The first is treating the area too strongly, which can flatten your natural expression around the eyes. The second, which I highlight, is placing the product too low, drifting down toward the upper cheek. When that happens, the injection reaches muscle involved in lifting the cheek during a smile.

Why misplaced crow's feet treatment freezes your smile

A genuine smile isn't just about the mouth. The cheeks lift, the skin around the eyes creases slightly, and the whole expression reads as authentic. If crow's feet treatment strays too far down and weakens the muscles that lift the cheek, the smile loses that fullness. Patients end up looking frozen or a little awkward, unable to produce a normal, relaxed grin. Some notice their smile looks lopsided or that their cheeks no longer rise the way they used to.

Done properly, crow's feet injections stay in a safe zone at the outer eye, well away from the cheek muscles that create your smile. The lines soften, but the expression stays yours. This is precisely the kind of subtlety that separates a rushed treatment from a considered one.

What a Careful, Doctor-Led Approach Looks Like

The thread running through all three mistakes is the same. They happen when an injector focuses on a single line or a single area without reading the face as a connected system. Good anti-wrinkle treatment starts before any needle appears, with an honest assessment of how your muscles move, how strong they are, and how they balance against each other.

At Wellface, treatment is doctor-led, which means the person assessing your face has trained extensively in facial anatomy. Muscle strength varies enormously from one person to the next, so a dose that suits one patient can be far too much or too little for another. That is why cookie-cutter dosing tends to disappoint. Your treatment should be mapped to your face, your movement patterns and the result you actually want.

It also helps to think of results as adjustable. A cautious first treatment followed by a two-week review lets me add a little more where needed, rather than starting too strong and waiting for it to wear off. Anti-wrinkle results typically settle over about two weeks and last somewhere in the region of three to four months, so there is time to fine-tune and there is no permanent commitment. If something isn't quite right, the next treatment can be adjusted accordingly.

Common Questions About Anti-Wrinkle Injections

How long does it take to see results?

Most people start to notice softening within three to five days, with the full effect settling by around two weeks. That two-week mark is a useful point for a review, because it is when I can see the true result and top up any area that needs a touch more.

Will my face still move naturally?

That is the aim. Natural movement is a sign of well-judged treatment, not a failure of it. The goal is to soften lines while you keep enough expression to look like yourself. A completely frozen forehead is usually a sign of overtreatment rather than a good outcome.

Is there any downtime?

Very little. You might have small red marks or the odd tiny bump at the injection sites for a short while, and these usually settle within an hour or two. Most people carry on with their day straight afterwards. I will ask you to avoid rubbing the area, strenuous exercise and lying flat for the rest of the day.

What if I have had a bad result elsewhere?

Heavy brows, frozen smiles and uneven results are frustrating, but they are temporary. Because anti-wrinkle treatment wears off over a few months, an unwanted result will gradually resolve. A thorough consultation can explain what likely went wrong and plan a more balanced approach for next time.

How do I choose a good injector?

Look for someone medically qualified who assesses your whole face rather than a single line, explains their plan clearly, and offers a follow-up review. My core message is worth repeating: see an advanced, experienced practitioner every single time, because the difference between a natural result and an obvious one is almost always down to skill.
