Songpa Jaw Botox Dermatology Clinic: Read This Before Getting Salivary Gland Botox | The Difference Between Xeomin and Coretox

Hello. I am Jin-young Lim, Medical Director of Piaf Clinic.

“Doctor, I came after seeing you on YouTube.

I’ve had jaw Botox so many times, but at some point, my lower face stopped getting slimmer altogether.

Is there something wrong with my face, or have I developed resistance?”

Nine out of ten patients who have recently visited our Songpa dermatology clinic express concerns like these.

When you look at Instagram or YouTube, everyone seems to get a V-line with a single Botox treatment. So why does my face stay the same even after getting Botox several times at a low-cost, high-volume clinic?

Today, from a doctor’s perspective, I will honestly explain the real reason you may have wasted money on lower-face Botox, along with the differences between resistance-free Botox products—Xeomin and Coretox—in one place.

Please focus for just three minutes.

Double Chin and Bulldog Jowls Near the Ears That Don’t Go Away Even After Botox?

Check “this.”

“I lost weight and my body became slim, but the areas under my ears and under my chin—the double-chin area—didn’t lose any fat, making my face look larger.”

“I had jaw Botox, but there is no noticeable effect when I look at myself from the front.”

If this sounds like you, raise your hand and touch your jaw right now.

When you clench your molars tightly, the hard, protruding area you can feel is indeed the jaw muscle, or masseter muscle.

However, if you can still feel a soft, thick lump under your ears or under your chin—the double-chin area—even after relaxing your molars, what could it be?

It may be neither fat nor muscle, but enlarged salivary glands—the parotid or submandibular glands.

Abnormal enlargement of the salivary glands caused by frequent late-night meals, highly stimulating foods, excessive stress, or temporomandibular joint disorders is called salivary gland hypertrophy.

No matter how many times you receive square-jaw Botox or contour injections intended to break down fat, they may not be effective in this case. The injections were being administered in the wrong area.

In such cases, the answer is salivary gland Botox, which reduces the size of the salivary glands rather than the masseter muscles. Treating both the square jaw and the salivary glands is necessary to create a smooth V-line extending from beneath the ears to the tip of the chin.

So, does that mean I should go in every month to get both my salivary glands and jaw treated?

No. You absolutely should not do that.

If you receive regular, indiscriminate treatments with standard Botox without giving it much thought simply because it is inexpensive, your body may develop neutralizing antibodies—resistance.

Once resistance develops, your body recognizes the Botox toxin as an enemy and rejects it, so eventually you may see no effect at all, no matter how much is injected.

Botox is used for cosmetic purposes, but it is also an essential medicine that may later be used to treat migraines or muscle disorders as you age.

If you develop resistance early in life because of cosmetic concerns, you may face the unfortunate situation of being unable to receive treatment when you actually need it.

That is why the terms currently going viral on YouTube and in beauty communities are pure toxins with no resistance: Xeomin and Coretox.

Xeomin vs. Coretox,

The Real Difference According to a Doctor

“Xeomin is too expensive, and I’m concerned because Coretox is made in Korea. Which one should I get?”

As a doctor, I will transparently explain only the facts. Both products share the same fundamental characteristic: they are pure toxins from which the “complexing proteins” that cause resistance have been completely removed.

Xeomin by Merz, Germany: “The original pure toxin.” With nearly 20 years of global clinical data, it has a very strong safety record. Its diffusion range—the extent to which it spreads to adjacent muscles after injection—is narrow and gentle, so concerns about side effects are relatively low. However, as an imported product, it is generally more expensive.

Coretox by Medytox: A “Korean pure toxin” that closely follows Xeomin. Animal-derived ingredients are excluded during the manufacturing process, further reducing the risk of infection. Its advantage is its cost-effectiveness, with a much lower financial burden than Xeomin thanks to Korean manufacturing technology.

If you want to trust the long-term clinical data and stability of the original imported product, choose Xeomin. If you want the effects while keeping costs reasonable, choose Coretox.

The important point is that, even if you pay a little more than you would for standard Botox, choosing a pure toxin with a lower resistance concern from the beginning can save you money in the long term.

Choosing a Dermatology Clinic in Songpa:

Consider This Before Comparing Prices

There are numerous high-volume dermatology clinics in and around Songpa.

There is nothing wrong with looking for an affordable clinic. However, Botox is not a simple procedure that can be finished in five minutes with a syringe.

Especially in the case of salivary gland Botox, an incorrect injection may affect the facial nerve inside the salivary gland or excessively reduce saliva production, potentially causing side effects such as severe dry mouth.

It is essential to accurately assess each patient’s salivary gland size, masseter muscle thickness, and lower-face symmetry from an anatomical perspective, and to administer the authentic product in the correct dosage.

This is also why, as a board-certified plastic surgeon, I precisely analyze the anatomical structure of each patient’s face before performing the procedure.

If you have been concerned that your lower face still looks broad even after losing weight, or if you have begun to worry about Botox resistance, please feel free to visit our dermatology clinic at any time.

Without unnecessary treatment, we will honestly help you with only the pure toxin treatment that you actually need.

Thank you for reading this long post.
