DaxibotulinumtoxinA-lanm
Peptide-stabilised neuromodulator with notably extended duration
Neuromodulators act on the muscle layer, not the skin surface, so skin tone and Fitzpatrick type do not affect safety or efficacy.
Daxxify is a newer muscle-relaxing injectable that works the same way as Botox but is designed to last longer, around six months on average instead of three to four. It's stabilised with a peptide rather than albumin, which means it contains no human or animal-derived components. It's a good option for people who want to cut down on how often they need top-ups.
DaxibotulinumtoxinA-lanm (Daxxify) is a novel botulinum toxin A formulation stabilised by a proprietary peptide excipient (RTP004) instead of human serum albumin. This peptide technology is associated with a significantly longer clinical duration, a median of 6 months versus 3–4 months for conventional toxins, with 24% of patients in Phase 3 trials maintaining results at 6 months. FDA-approved in 2022, it is the first new neuromodulator with a meaningfully differentiated duration profile in two decades.

The SAKURA 1 and 2 Phase 3 trials (Bertucci et al., PRS 2022; n=609 combined) showed median duration of 6 months for 40U glabellar treatment, with 24% of patients maintaining a none-or-mild response at week 24, a statistically significant improvement over historical 3-4 month benchmarks for onabotulinumtoxinA.
- ✓
Daxxify contains no human or animal-derived components, unlike Botox which uses human serum albumin as a stabiliser. This may be relevant for patients with albumin sensitivities or those preferring non-animal-derived products.
- ✓
Safety profile from SAKURA trials was consistent with established neuromodulator class effects: headache (5%), injection site reactions (4%), eyelid ptosis (1%). No new safety signals were attributable to the peptide excipient in the trial population.
- ✓
The same class-wide risks that apply to all botulinum toxin A products apply to Daxxify: ptosis, spread to unintended muscles, and the rare possibility of systemic spread. The longer duration means that if a complication such as ptosis or asymmetry occurs, it persists longer than with a 3-month product before self-resolving. This increases the clinical significance of placement errors.
- ✓
Post-marketing real-world data at 2 years is consistent with SAKURA trial findings on safety. No new adverse signal from the peptide excipient has emerged, but post-market surveillance at 3 and 5 years is not yet available.
- ?
Real-world duration data is still accumulating. Phase 3 results reflect controlled trial conditions; post-marketing observations suggest some patients experience shorter or longer duration than the 6-month median.
- ?
Whether longer toxin duration affects antibody formation rates compared to shorter-duration products. The theoretical concern is that sustained receptor occupancy may present a different immunogenic profile, but no clinical data exists to confirm or refute this.
- ?
Optimal dosing for areas beyond the glabella (forehead, crow's feet, masseter) is being characterised in post-approval studies. Using Daxxify in off-label areas without established dosing protocols carries higher technique uncertainty than for onabotulinumtoxinA, which has decades of off-label dosing data.
- ?
Whether the longer duration product increases the clinical risk of muscle atrophy or facial structural change with repeated long-term use compared to shorter-duration toxins is not studied.
SAKURA 1 & 2: Phase 3 trials of daxibotulinumtoxinA-lanm for glabellar lines
Bertucci et al. · Plastic and Reconstructive Surgery · 2022
In two Phase 3 RCTs (n=609 combined), 24% of patients treated with 40 U maintained a none-or-mild response to glabellar lines at week 24, with a median duration of 6 months, approximately 50% longer than conventional neuromodulators.

Clinic checklist
Universal
- Check the practitioner is licensed and registered. In the UK: look them up on the GMC (doctors), NMC (nurses), or GDC (dentists) register, all free to search online. In the US: search your state medical board. Takes 2 minutes. If they cannot tell you their regulatory body, leave.
- Ask to see the product box before treatment. It should be factory-sealed with a visible lot number and expiry date. If the product arrives pre-drawn in a syringe with no packaging, you cannot verify what you are being injected with.
- You should receive a written consent form before treatment. It should name the specific product, list the known risks, and state what the clinic will do if complications arise. A single generic form with no product name is not adequate.
- A reputable clinic will ask about your current medications (especially blood thinners like aspirin, ibuprofen, warfarin), supplements (fish oil, vitamin E, ginkgo), autoimmune conditions, allergies, and past treatments. If no one asks, they are skipping a safety step.
- Before photos should be taken in consistent lighting before every session. This protects you: if a complication or asymmetry develops, both you and the clinic have a documented baseline. If a clinic does not take before photos, they are not tracking outcomes.
- Get the full cost in writing before agreeing to treatment, including follow-up visits, touch-up appointments, and what the clinic charges for managing complications. Verbal quotes are not binding.
Procedure-specific
- Ask: have you treated patients with Daxxify specifically, and what duration are you seeing in your own practice? Daxxify is newer, and you deserve to know whether your injector has real experience with it or is switching from Botox without Daxxify-specific practice.
- Ask: how do you approach the first Daxxify treatment, do you start more conservative than you would with Botox? Because Daxxify can last six months or longer, an over-correction persists significantly longer than with a 3-month product. An injector who plans to dose aggressively from the start without mentioning this is not accounting for the extended commitment you are making.
