Masseter Botox & hyperhidrosis in Basingstoke — the treatments that fix problems, not lines
By the LUMOS Clinic team · LUMOS Clinic, Basingstoke | 6 minute read
Most people think of Botox as something that smooths wrinkles. But the same medicine does two genuinely medical jobs that have nothing to do with lines on the face: relaxing an overworked jaw muscle (masseter) and stopping excessive underarm sweating (hyperhidrosis). These are functional treatments — they solve a problem rather than a sign of ageing. This page covers what they do, what they cost in Basingstoke, and who they genuinely help.
Masseter Botox — for grinding, clenching and a tight jaw
The masseter is the large muscle at the back of the jaw, and for many people it is constantly overworked — clenching through the day, grinding at night, or both. Over time this leads to jaw tension, headaches, worn teeth, and a visibly squared or overdeveloped jawline as the muscle grows.
Masseter Botox relaxes that muscle. The effect is twofold: it eases the grinding and clenching (and the tension and headaches that come with them), and it can soften the jawline as the overbuilt muscle relaxes over a few weeks.
What it costs: masseter Botox at LUMOS starts from £280, depending on the dose — which is set by the size and strength of your muscle, assessed at consultation. Results typically last around 3–6 months.
Hyperhidrosis — for excessive underarm sweating
Hyperhidrosis is excessive sweating beyond what temperature or exertion explains. For people affected, it’s not a minor embarrassment — it disrupts work, clothing choices and confidence, often for years without a clear answer.
Botox treats it by blocking the chemical signal that tells the sweat glands to produce. The result is a dramatic, reliable reduction in underarm sweating, usually lasting around six months.
What it costs: hyperhidrosis treatment at LUMOS starts from £380. It’s a practical, high-impact treatment for a genuinely distressing condition.
Who these are for — and who they aren’t
Masseter Botox suits people who clench or grind (especially if it causes pain, headaches or worn teeth), and those who want to soften a jaw that has become squared from muscle overuse. If the concern is fat or bone structure rather than muscle, it’s a different conversation — and I’ll say so honestly.
Hyperhidrosis suits people with excessive, unexplained underarm sweating that affects their day-to-day life. It’s worth mentioning that Botox is one of the standard treatments for this — but I’ll confirm the picture at consultation.
The honest boundary: these are prescription-only treatments and should be done by someone properly qualified. At LUMOS they’re administered by the LUMOS Clinic team, an Independent Nurse Prescriber — which matters because dose and placement are what make them work safely.
What to expect
Both are quick, simple injection treatments with no downtime. You can return to your day immediately. Results are gradual over the following days to weeks — the muscle or sweat-gland signal relaxes over time rather than instantly.
Masseter results build over two to three weeks as the muscle relaxes. Hyperhidrosis reduction is usually noticed within the first week or two and lasts around six months.
Common questions
Is masseter Botox safe?
Yes, when done properly by a qualified prescriber. The dose and placement matter — too little does nothing, too much or poorly placed can affect chewing. Georgie assesses the muscle and doses conservatively.
Will masseter Botox change my face?
It can soften an overdeveloped, squared jawline as the muscle relaxes — which many people want. It won't affect bone or fat. The change is gradual and natural over a few weeks.
Does hyperhidrosis Botox hurt?
The underarm has thin, sensitive skin, so a numbing cream is applied first. Most people find it very manageable and the benefit far outweighs the brief discomfort.
How long does each treatment last?
Both typically last 3–6 months. Many people have two to three treatments a year to stay on top of the symptom.
