Yes, Botox for migraines does reduce wrinkles, particularly on the forehead and between the eyebrows. In a clinical study of patients receiving the standard migraine protocol, 74.2% reported noticeable aesthetic improvement after treatment. This isn’t a guaranteed cosmetic makeover, but the overlap between migraine and cosmetic injection sites means most people walk away with smoother skin as a bonus.
Why Migraine Botox Affects Wrinkles
The migraine protocol, known as PREEMPT, involves 31 injections spread across seven muscle groups: the forehead, the area between your brows (glabella), temples, back of the head, neck, and shoulders. Several of these sites sit in exactly the same muscles that cosmetic Botox targets. The frontalis muscle across your forehead gets 20 units, and the corrugator and procerus muscles between your brows get 10 units. Those are the same muscles responsible for horizontal forehead lines and the vertical “11” lines between your eyebrows.
When Botox relaxes a muscle to block migraine pain signals, it also stops that muscle from creasing the skin above it. The wrinkle reduction isn’t an added ingredient or a different mechanism. It’s the same effect, just serving two purposes at once.
How Much Wrinkle Improvement to Expect
The cosmetic benefit is real but not identical to what you’d get from a dedicated aesthetic treatment. A study published in Toxins measured wrinkle severity before and after migraine Botox using a standardized scale. Forehead wrinkle severity at rest dropped from a median score of 1.5 to 0 (on a 0 to 3 scale), and frown lines between the brows dropped from 2 to 1 during maximum contraction. Both changes were statistically significant.
Most patients were satisfied with the cosmetic results. Only 2% reported any worsening of frown lines, and 4% noticed worsening of forehead wrinkles. So the odds strongly favor improvement, or at least no change, rather than looking worse.
That said, a full cosmetic Botox session is tailored specifically for appearance. Your provider can place injections precisely to lift certain areas, soften crow’s feet, or shape the brow. The migraine protocol follows a fixed pattern designed for pain prevention, so the cosmetic results are a side effect rather than the goal. You’ll likely see the most smoothing on your forehead and between your brows, with little to no effect on crow’s feet or other areas that aren’t part of the migraine protocol.
How the Two Protocols Differ
A migraine session uses 155 to 195 units of Botox total, spread across all 31 sites from forehead to shoulders. A typical cosmetic forehead and brow treatment uses far fewer units, often 20 to 40 in total, concentrated only in the areas that cause visible lines. The migraine dose hitting your forehead (around 30 units between the frontalis, corrugator, and procerus) is comparable to a cosmetic session for those specific zones, which explains why the wrinkle-smoothing effect is noticeable there.
The treatment schedule also lines up reasonably well. Migraine Botox is given every 12 weeks, and cosmetic Botox typically lasts three to four months before wearing off. So the refresh cycle for wrinkle reduction roughly matches the migraine maintenance schedule.
Adding Cosmetic Botox on Top
If you want wrinkle treatment in areas the migraine protocol doesn’t cover, like crow’s feet or lip lines, it is possible to get cosmetic Botox alongside your migraine treatments. Cleveland Clinic notes that your provider needs to approve this, because receiving too much Botox too close together can increase side effects or cause your body to develop resistance over time. You may need to space out the two treatments by a few weeks rather than doing them on the same day.
This is worth discussing with your provider before your next session, especially if you’re already happy with the forehead smoothing and just want touch-ups elsewhere.
Potential Cosmetic Side Effects
Because migraine injections follow a fixed pattern rather than a customized cosmetic plan, there’s a small chance of unwanted aesthetic effects. Johns Hopkins Medicine lists drooping of one eyelid, an uneven eyebrow, or drooping on one side of the mouth as possible side effects. These are typically temporary, resolving as the Botox wears off over several weeks, but they’re more common with the higher doses used in migraine treatment compared to cosmetic-only sessions.
Dry or watery eyes can also occur when injections near the brow affect the muscles around the eye. If you notice any drooping or asymmetry, let your provider know so they can adjust the placement at your next appointment.
Insurance and Cost Considerations
Insurance covers Botox for migraines as a medical treatment, but only for chronic migraine, defined as 15 or more headache days per month for at least three months, with at least 8 of those days meeting migraine criteria. The FDA has not approved it for episodic migraine (14 or fewer headache days per month), and insurance won’t cover it for that use.
The cosmetic benefit you get from migraine Botox comes at no extra cost since it’s part of the same injections. If you add a separate cosmetic session for areas outside the migraine protocol, that portion is typically out of pocket. For many patients, the built-in wrinkle reduction from their covered migraine treatment is enough to skip a separate cosmetic appointment altogether.
