Salivary Gland Botox — PECHE Clinic, Gangnam Station

Salivary Gland Botox

Salivary Gland Botox places botulinum toxin into the salivary gland below the ear or below the jaw, reducing that gland's activity. As the activity eases, the gland's bulk comes down with it — and the line of the lower face that flared outward turns gentler.

▲ An anatomical drawing with the facial skin removed — the apricot-colored mass spread in front of and below the ear is the parotid gland, and the smaller mass beneath the ivory jawbone is the submandibular gland. The thin line running forward from the parotid is the duct through which saliva flows into the mouth

A salivary gland is the organ that makes saliva and sends it into the mouth through a duct. Saliva is made when the nerve sends the "release" signal — and botulinum toxin reduces the release of that signal. With less signal, the gland works less, and tissue that stayed swollen comes down in bulk too.

When to Consider It

• The line from below your ear to your jaw flares outward
• You can feel a soft, plump mass when you press below your ear
• You've lost weight, but your lower face's width hasn't budged
• People say the area under your jaw always looks puffy
• One side is plumper, making the face look uneven

If the width comes not from the salivary gland but from fat, muscle, or the jawbone, this treatment won't change it. We confirm which one it is together, based on your assessment.

Where the Salivary Glands Sit

A salivary gland is neither muscle nor fat — it's the organ that makes and releases saliva — so the injection site differs from other Botox treatments. The parotid spreads wide from in front of the ear to behind the lower jaw; the submandibular sits beneath the jawbone. Which of the two is plump decides where the dose goes.

▲ A vertical cross-section at the gland's site — beneath the epidermis, dermis, and yellow subcutaneous fat, the apricot tissue clustered like grapes is the salivary gland. The needle tip and teal product stay within it

The action stays in the injected gland alone. The mouth holds several small salivary glands working on their own, so dryness that disrupts daily life is rare.

How It's Done

1. Assessment A 3D MetaVu scan captures your facial contours and left–right balance.

2. Cause check We feel below the ear and jaw directly — is the plumpness gland or fat, and which side is larger?

3. Site and dose We settle whether the dose goes below the ear or below the jaw, and how much to each side. The amount needed follows the gland's size.

4. Numbing A cold roller dulls the sensation before we start.

5. Injection Divided doses go into the gland tissue, with depth and placement set so it doesn't spread to the chewing or expression muscles nearby.

6. Aftercare guidance We go over what to follow for the day.

Results and Recovery

Item	Details
Where it acts	The parotid or submandibular gland — the saliva-making organ below the fat layer
What changes	That gland's activity and bulk — and with it, the width of the lower face
When results show	Begins around days 3–7, clearest at week 2, with the bulk change emerging gradually over the following weeks — the signal doesn't cut off at once; it tapers over several days
How long it lasts	3–6 months
Repeat interval	Set within the 3–6 month window, watching how much of the bulk returns
Pain	The needle goes in deep, and a heavy, dull ache passes briefly through the depths below the ear or jaw
Pain control	A cold roller dulls the sensation before we start
Downtime	The marks at the injection points settle within 1–2 hours; you can wash your face and wear makeup after 2–3 hours · bruises, if any, fade within 3–7 days
For the day	Don't lie down for 4–6 hours · skip saunas, hard exercise, and massaging the treated area — all to keep the product from spreading beyond where it was placed
What you may notice early on	A light ache below the ear or jaw when eating — for the first 1–2 weeks or so
Dry mouth and swallowing	The mouth's other small glands keep working, so dryness or difficulty swallowing is rare

Expected Reactions and Possible Side Effects

Common, temporary reactions — part of the normal response:

• Marks at the injection points, settling within 1–2 hours
• Bruises, if any, fading within 3–7 days
• A light ache below the ear or jaw when eating may occur for the first 1–2 weeks or so

Anything beyond this is uncommon. If a reaction lasts longer than expected or worsens, contact us and we'll check it with you.

What We Check Beforehand

If any of these apply to you, let us know during your consultation. We postpone or adjust the timing.

• Pregnancy or breastfeeding
• Conditions affecting the point where nerves meet muscles, such as myasthenia gravis — the very site where botulinum toxin acts, so symptoms could worsen
• Medications that affect nerve–muscle signaling (including some antibiotics)
• A mouth that's often dry already, or medication that causes dry mouth
• Difficulty swallowing
• A gland that hurts or has swollen suddenly — we check for inflammation first
• Inflammation or wounds at the injection site
• Aspirin or blood thinners (anticoagulants) — bruising can be heavier, so tell us in advance and we'll plan for it
• Botulinum toxin received elsewhere recently — tell us when, with which product, and how much, and we'll recalculate the total amount given in one session and the interval to your next treatment

How PECHE Clinic Does It

We sort out the cause first. The lower face widens for several reasons beyond the salivary glands. With what we feel by touch, the contours and balance confirmed in your scan, and standards built from over 90,000 treatments, we first check whether the gland is the cause — then set the site and dose.

We offer four botulinum toxin products. Botulinum toxin is a substance produced by bacteria. The bacteria send it out wrapped in other proteins to keep it intact — but only the core inside produces the effect; the wrapping plays no part in it. The core is identical across all four products; what differs is that some products keep the wrapping, and some strip it away to leave only the core.

Product	Made by	Protein wrapping	Albumin (storage aid)
Newlux	Medytox, Korea	Kept	Used
Coretox	Medytox, Korea	Stripped away	Not used
Xeomin	Merz, Germany	Stripped away	Used
Allergan Botox	AbbVie, USA	Kept	Used

What keeping or stripping the wrapping means. The wrapping protects the core — but it also means foreign proteins unrelated to the effect enter your body along with it. Repeated over the years, your body can come to recognize and respond to those proteins — and then the same dose may not work as well as it once did. Stripped products leave less room for that. For a one-off treatment the difference is negligible; it matters when you plan to continue over several years.

Albumin is a common protein naturally present in human blood. It keeps the core from degrading while the drug is stored as a dried powder — and Coretox does without it too. The salivary glands are an area where the total amount going in at once tends to add up when treated alongside other parts of the face — so we look at what else you're having the same day, and your plan ahead, together with the product.

We open the genuine product in front of you — and you can watch it being dissolved through the glass wall, too. Botulinum toxin doesn't keep long once dissolved, so it's stored as a powder and dissolved in saline just before treatment. The more diluted it is, the larger its volume — and the wider it spreads. The dose follows the gland's size, so it's worth seeing for yourself what was dissolved and how much. You see which product is opened right in front of you, and the dissolving itself is visible through the glass wall from the waiting area.

If the gland isn't the cause, we say so. If fat, muscle, or bone is the cause, this treatment won't deliver the change you want. We tell you the expected range first and let you decide — and you're welcome to come in just for a consultation.

FAQ

Q1. Who performs the treatment? A: PECHE physicians who all work to the same injection standards, built from over 90,000 documented treatments. The chewing and expression muscles pass close by the glands, and a misplaced depth or position could affect expression or chewing — so that judgment is made by these standards, not by feel.

Q2. Won't my mouth go dry? A: What eases is the injected gland's activity — and the mouth holds several small salivary glands working on their own. So dryness that disrupts daily life is rare. If your mouth is often dry already, or you take medication that dries it, tell us beforehand.

Q3. How do I know if it's the gland or fat? A: They feel different and sit in different places. A gland is a soft mass at its set location — in front of and below the ear, or beneath the jawbone — while fat spreads wider and shallower. We confirm the contours and balance in your scan and feel the area together to tell them apart.

Q4. Will eating or swallowing be affected? A: We set the depth and placement so the dose stays within the gland tissue, and trouble swallowing is rare. For the first week or two, a light ache below the ear or jaw when eating can occur, fading with time.

Q5. What should I look for when choosing a clinic? A: Whether they first tell gland from fat, and whether they compare the two sides' size separately. Skip that, and you can end up treated when the cause was different — or with the asymmetry left in place.
