Quick answer: When people call Xeomin "double purified" or "naked," they mean its manufacturing removes the accessory proteins that surround the active botulinum toxin in other brands, leaving only the active molecule. It works on lines the same way Botox does and lasts about three to four months. Some patients who stopped responding well to other neuromodulators switch to it. See our Xeomin in Frisco page to book.
The active molecule in every cosmetic neuromodulator on the market is roughly the same size: about 150 kilodaltons of purified botulinum toxin type A. What differs is everything packed around it. In most formulations, that active molecule travels bundled with accessory clostridial proteins that carry no therapeutic activity at all — Merz, the manufacturer of Xeomin, puts the figure at up to 83% of the total protein mass in other products. Xeomin is the formulation built to leave that mass out.
That single manufacturing difference is why patients in Frisco keep asking about it, and why the answer is more interesting than "it's the cheaper Botox." This guide walks through what Xeomin actually is, what the purification does and does not change, and how Carm, BSN, RN decides whether it belongs in your treatment plan at Bellissima BB Med Spa.
Xeomin is the brand name for incobotulinumtoxinA, a purified form of botulinum toxin type A used to soften the lines that repeated facial expression etches into the skin. It works the way every neuromodulator works: injected into a specific muscle, it temporarily interrupts the signal telling that muscle to contract. The muscle relaxes, the skin above it stops folding, and over a few weeks the crease it was creating softens.
For aesthetic use it is FDA-approved to treat moderate to severe upper facial lines — frown lines between the brows, horizontal forehead lines, and crow's feet at the outer corners of the eyes. Those are the same three areas most Frisco patients come in asking about, which is part of why it slots so cleanly into an existing treatment plan.
Results typically develop over several days, reach their full effect at around the two-week mark, and hold for approximately three to four months before movement gradually returns. If those numbers sound familiar, they should — they are effectively the same as Botox. The purification story is real, but it is not a longevity story.
Botulinum toxin is produced by bacteria, and in nature the active neurotoxin does not exist alone. It comes wrapped in a complex of accessory proteins — sometimes called complexing proteins or clostridial proteins — that protect the molecule in its natural environment. Traditional manufacturing keeps that complex intact, which is why other formulations weigh in at roughly 900 kilodaltons.
Xeomin is made using a process Merz calls XTRACT Technology, which filters those accessory proteins out. What is left is about 150 kilodaltons: approximately six times less protein mass, essentially the active molecule on its own. Merz markets this as being "double filtered to remove the complexing proteins that can reduce effectiveness over time."
Here is the part worth understanding clearly, because it is where marketing and evidence diverge. The accessory proteins do not make a product work better or worse in a single session. Their relevance is immunologic: they add protein load, and protein load is one of the variables researchers associate with the body eventually forming antibodies to the toxin. A patient who has had two treatments in their life has essentially no stake in this. A patient who has been treating the same three areas every twelve weeks for eight years has more of one.
The prevalence of true immunologic resistance in aesthetic patients is low. A 2025 narrative review in JMIR Dermatology puts the estimated neutralizing antibody rate in aesthetic use at roughly 0.2% to 0.4% — far below the 0.3% to 27.6% range reported across therapeutic applications, where doses are much larger and intervals often shorter.
Where the formulation difference shows up is in the subset of patients who do stop responding. In the data that review summarizes, among patients with secondary non-response, neutralizing antibodies were detected in 32.5% of those treated with onabotulinumtoxinA and 56.7% of those treated with abobotulinumtoxinA — while none of the patients receiving incobotulinumtoxinA developed secondary non-response at all. That is a small dataset, not a guarantee, and it should be read as a signal rather than a promise. But it is the honest reason a purified formulation is worth discussing with long-term neuromodulator patients in Frisco rather than dismissing as marketing.
Onset, duration and the feel of the result are broadly comparable. In head-to-head study data, days to onset and days of duration were similar between the two. The injection experience is the same — the same fine needle, the same handful of small injections, the same ten-to-fifteen-minute appointment. Aftercare is identical. Downtime is effectively nil for both.
The safety profile is also comparable. Both are botulinum toxin type A, both carry the same class warnings, and both require the same screening before treatment. Neither is appropriate for someone who is pregnant or breastfeeding, and both call for a careful medical history before a single unit is drawn up.
Three things. First, the protein load, for the reasons above. Second, the way each product is stabilized and handled in the clinic, which is a manufacturing detail rather than something you experience. Third — and this is the one patients most often get wrong — the units.
This is the single most common misunderstanding we correct at Bellissima BB Med Spa. Merz states it plainly: the potency units of Xeomin are specific to that preparation and its assay method, and they are not interchangeable with units of any other botulinum toxin product. There is no conversion factor you can look up. "I get 20 units of Botox in my forehead, so give me 20 units of Xeomin" is not a request that means what the patient thinks it means.
In practice, the number often lands in a similar neighborhood, but it is arrived at by assessing your anatomy, not by arithmetic on a previous invoice. If you want to understand how that assessment works, our guide to how many units of Botox you actually need walks through the reasoning area by area. The same logic applies here: the muscle's strength and size decide the dose, not the product's name.
This is also why bringing your treatment history to a consultation matters more than bringing a number. What we want to know is which areas were treated, how long the result held, and whether anything about it disappointed you — not the unit count on a receipt from a different clinic using a different product.
There is no patient type for whom Xeomin is the only correct answer. There are, however, several situations where it comes up first in conversation.
And a group for whom it is usually not the first suggestion: patients whose main frustration is having to come back every three months. Duration is the thing Xeomin does not change. That conversation belongs with Daxxify, which is formulated with a stabilizing peptide instead of accessory proteins and is frequently cited as holding longer for frown lines.
Xeomin softens dynamic lines: the ones created by movement. Frown lines between the brows, forehead lines, crow's feet. Because it quiets the muscle rather than filling anything, it is the right tool when the line appears or deepens when you make an expression.
It is the wrong tool for volume. Hollowing in the cheeks, thinning lips, and static folds that sit there whether your face is moving or not are volume problems, and a neuromodulator will not correct them. That distinction is worth understanding before your consultation — our guide to Botox versus filler covers where the line falls.
It is also worth being clear about scope: everything discussed here is cosmetic. Bellissima BB Med Spa treats expression lines for aesthetic reasons, and any medical use of botulinum toxin is a conversation for a physician, not a med spa.
Every patient at Bellissima BB Med Spa completes a Good Faith Exam before any treatment. That is not a formality — it is a review of your medical history, medications, prior neuromodulator experience and what you actually want your face to do, conducted by Carm, BSN, RN, a licensed registered nurse with more than thirty years of medical experience across emergency medicine, anesthesia recovery and surgical settings, working under physician oversight.
This is where dosing gets decided. Carm assesses your muscle strength and movement pattern directly — asking you to frown, raise your brows, and squint — because two patients with identical-looking foreheads at rest can need meaningfully different doses once they move.
The treatment itself takes about ten to fifteen minutes. Xeomin is delivered through a very fine needle in a series of small injections placed according to your anatomy. Most patients describe it as a brief pinch or sting per injection rather than pain. No anesthetic is typically needed, though ice is available.
You will leave with small raised bumps at the injection sites that settle within fifteen to thirty minutes, and occasionally a pinpoint of redness. There is no bandage, no recovery, and nothing that stops you going back to work.
Nothing happens immediately, and that is normal. Most patients notice the first softening somewhere between day three and day five. The result continues to develop and reaches full effect at around day fourteen. Judging your outcome at day four is the fastest way to be needlessly disappointed by a treatment that is working correctly.
We schedule a follow-up conversation at the two-week mark for new patients. If an area needs adjusting, that is the moment to assess it — and to note it for next time, since the point of a plan is that each round is better informed than the last.
The aftercare list for Xeomin is short, and shorter than most of the internet suggests. For the first four hours, stay upright and avoid rubbing, massaging or pressing on the treated areas — that includes facials, and it includes sleeping face-down. Skip strenuous exercise for the rest of the day. Avoid heat exposure such as saunas and hot tubs for twenty-four hours, which in a North Texas summer is less trivial than it sounds.
Do not book a Xeomin appointment three days before a wedding, a photo shoot or a reunion. Because the result develops over two weeks, the useful rule is to treat at least two weeks ahead of anything you care about looking your best for, and ideally three. Our wedding-day timeline guide lays out the full schedule.
The honest framing is that all three are good products and the differences are smaller than the marketing implies. A rough guide:
If you want the side-by-side in more depth, our comparison of all three covers longevity, formulation and cost logic together. And if you would rather not choose in advance, that is fine — deciding is part of what the consultation is for.
Bellissima BB Med Spa is a private, one-on-one injectables studio inside Mattison Avenue Salon Suites on Warren Parkway in Frisco, TX, serving patients from Frisco, Plano, McKinney, Prosper, Allen and North Dallas. Every treatment is performed by Carm herself — there is no rotating staff and no assembly line.
If you are considering Xeomin, come in for a consultation rather than a decision. Book your consultation and we will look at your face, talk through what has and has not worked before, and build a plan that fits it. You can also read more about Carm and her background before you come in.
No, but they are close relatives. Both are botulinum toxin type A, both relax the same expression muscles, and both last around three to four months. The difference is formulation: Xeomin is purified to remove the accessory complexing proteins that other products carry, leaving roughly 150 kilodaltons instead of about 900.
Generally no. Study data shows onset and duration were similar between the two, and both typically hold for approximately three to four months. If duration is your main concern, Daxxify is the product worth discussing rather than Xeomin.
Not necessarily, and the question is slightly misleading. Xeomin units are specific to Xeomin and are not interchangeable with any other product's units, so there is no conversion. Your dose is determined by your muscle anatomy at your consultation, not by arithmetic on a previous treatment.
Yes, and it is a common switch. There is no washout period required and no need to wait beyond your normal treatment interval. Bring your history — which areas, how long results held, what you liked or didn't — and Carm will build the Xeomin plan from your anatomy rather than from your old unit count.
Most patients describe a brief pinch or sting per injection and nothing beyond that. The needle is very fine, the injections are shallow, and the whole treatment takes ten to fifteen minutes. Ice is available if you would like it.
The first softening usually appears between day three and day five, and the full result develops by around day fourteen. Do not judge your outcome before two weeks — a result that looks incomplete on day four is almost always a result that is still developing.
Xeomin is FDA-approved for moderate to severe upper facial lines and has the same class safety profile as other botulinum toxin type A products. Safety in practice comes down to screening and technique, which is why every patient at Bellissima completes a Good Faith Exam with Carm, BSN, RN before treatment. It is not appropriate during pregnancy or breastfeeding.
