After Dysport injections, you should stay upright for at least 4 hours before lying down, then sleep on your back for the first night. These two steps help the neurotoxin settle into the targeted muscles rather than drifting into surrounding tissue. Most post-treatment sleep restrictions lift after 24 hours.
Why the First Few Hours Matter
Dysport needs time to bind to the muscles where it was injected. During the first 4 hours, the product is still settling in, and lying down too soon can cause it to migrate to nearby muscles. That migration is what leads to unintended side effects like weakness in the wrong muscles, uneven results, or drooping in areas that weren’t meant to be treated.
Staying seated or standing during this window also reduces swelling and bruising at the injection sites. If your appointment is in the late afternoon or evening, the simplest approach is to stay upright until bedtime rather than napping right after treatment. If you tend to get injections earlier in the day, the 4-hour window will pass well before you go to sleep.
Best Sleeping Position the First Night
Back sleeping is the standard recommendation for the night after Dysport. Lying face-down or on your side presses your skin against the pillow, which can push the product away from where it was placed. Sleeping on your back keeps pressure off the treated areas entirely.
If you’re not naturally a back sleeper, a couple of tricks can help. Placing a pillow on each side of your body creates a gentle barrier that discourages you from rolling over. Elevating your head slightly with an extra pillow can also reduce any minor swelling that developed at the injection sites. You don’t need to sleep perfectly still all night. The goal is simply to start on your back and avoid sustained pressure on your forehead, brow, or wherever you were treated.
After 24 hours, you can return to whatever sleep position feels comfortable.
Skip the Eye Mask and Heat
If you normally wear a sleep mask, leave it off for the first night. Any accessory that presses against or near the injection sites adds unnecessary risk during the settling period. The concern isn’t just pressure but also heat. Heated eye masks, in particular, increase blood flow to the face, which can encourage the product to spread and raise the chance of bruising.
The same logic applies to your pre-bed routine. Hot showers, saunas, and hot baths all increase circulation in your face. Stick to lukewarm water when washing up before bed on the night of treatment. Most providers suggest avoiding direct heat exposure to treated areas for at least 24 hours, with some recommending 48 hours to be cautious.
Alcohol and Exercise Before Bed
A glass of wine or a workout before bed might be part of your normal routine, but both are worth skipping on injection day. Alcohol dilates blood vessels, which increases blood flow to your face and raises your bruising risk. Exercise does the same thing by elevating your heart rate and blood pressure. Together, these effects can cause Dysport to spread from the targeted muscles and reduce how well the treatment works.
Light activity like walking is fine, but anything that makes you sweat or strain should wait until the next day. If you rely on evening exercise to fall asleep, try a gentle stretching routine instead, keeping your head above your heart throughout.
What to Watch for the Next Morning
When you wake up, check the treated areas in a mirror. Some mild swelling, redness, or tiny bumps at the injection sites are normal and typically fade within a few hours. What you’re watching for is anything that suggests the product moved where it shouldn’t have.
The most recognizable sign of migration is eyelid drooping, known clinically as ptosis. This happens in roughly 3% of people who get injections in the forehead or between the brows, and it can appear anywhere from 2 to 10 days after treatment. A drooping eyelid doesn’t mean something went wrong with how you slept. It can happen even with perfect aftercare. But if you notice one eyelid sitting noticeably lower than the other, or if your brow feels unusually heavy on one side, contact your injector. The effect is temporary and treatable, but it’s worth addressing early.
Asymmetry that appears in the first day or two is more often swelling than migration. Give it 48 hours before drawing conclusions about your results. Dysport takes several days to reach its full effect, so what you see on day one is not the final outcome.
