The first 24 hours after Botox are when the toxin is settling into your targeted muscles, and a few common mistakes during this window can lead to uneven results, extra bruising, or shorter-lasting effects. Most aftercare rules come down to one principle: avoid anything that increases blood flow to your face or puts pressure on the injection sites.
Don’t Lie Down for Several Hours
Try to stay upright for three to four hours after your appointment. Lying flat too soon can allow the Botox to shift from where it was injected into nearby muscles, potentially creating uneven results. This is especially important for forehead and between-the-brow injections, where migration into the wrong muscle can cause a drooping eyelid. That kind of drooping, called ptosis, happens when the toxin seeps into the muscle that holds your upper eyelid open. It’s not permanent, but it takes four to six weeks to resolve on its own.
Skip the Gym for at Least 24 Hours
Most providers recommend waiting a full 24 hours before any strenuous exercise. The reason is straightforward: intense activity increases blood flow throughout your body, including your face. That extra circulation can push Botox away from the muscles your injector targeted, leading to weaker or uneven results. Even exercises that don’t seem face-related, like running or heavy lifting, raise your heart rate enough to matter.
Light walking is generally fine. The concern is with anything that gets your heart pounding or has you bending forward repeatedly, like yoga inversions or cycling.
Avoid Heat Exposure
Saunas, steam rooms, hot tubs, and hot yoga all dilate blood vessels and increase circulation in the same way exercise does. Heat during the first 24 hours can make any mild swelling or bruising worse and may prevent Botox from fully settling into the target muscles. When the toxin is disrupted early, results tend to be softer or shorter-lasting than normal.
Direct sun exposure falls into this category too. For the first 24 hours, your skin at the injection sites is more sensitive than usual, and sun can increase redness, swelling, and bruising risk. For the first week, protect your face with SPF 30 or higher, sunglasses, and a hat if you’re spending time outdoors in strong sun.
Don’t Touch, Rub, or Massage Your Face
Pressing on the injection sites can physically push the Botox into unintended areas. That means no facial massages, no gua sha, no rubbing your forehead, and no professional facials for at least 24 hours. Some providers suggest waiting even longer for treatments that involve deep pressure or manipulation of the skin, like microdermabrasion or chemical peels. When in doubt, give it a few days before putting any real pressure on the treated areas.
This also applies to wearing tight headbands, hats that press against your forehead, or goggles. Anything that creates sustained pressure on or near the injection sites during the first day is worth avoiding.
Hold Off on Alcohol
Most Botox providers recommend avoiding alcohol for 24 to 48 hours after treatment. Alcohol thins your blood, which increases the risk of bruising at the injection sites. It also dehydrates your skin and widens blood vessels, which can make your face look flushed and worsen any post-treatment swelling. Botox itself can cause mild dizziness or drowsiness in some people, and alcohol makes both of those worse.
If you can, it’s also worth skipping alcohol for 24 hours before your appointment for the same bruising-related reasons.
Watch Out for Blood-Thinning Medications and Supplements
This one is really a “before and after” precaution. Aspirin, ibuprofen (Advil, Motrin), naproxen (Aleve), fish oil supplements, and vitamin E supplements all thin the blood and increase bruising risk. The standard recommendation is to avoid these for two weeks before your appointment, but continuing to avoid them for a day or two afterward also helps minimize bruising. If you need pain relief after your injection, acetaminophen (Tylenol) is generally the safer option since it doesn’t have the same blood-thinning effect.
If you take any of these as prescribed medications rather than over-the-counter choices, talk with your prescribing doctor before stopping them. The bruising concern is cosmetic, not dangerous.
Sleep on Your Back the First Night
The first night after Botox is the highest-risk window for migration caused by pressure on your face. Sleeping on your back with your head slightly elevated on an extra pillow is the safest approach. Side sleeping and stomach sleeping both press your face into the pillow, which can shift the toxin before it’s had time to bind to the muscle.
After 24 hours, the risk of migration from sleep position drops significantly. If you want to be extra cautious, some providers suggest back-sleeping for a full 48 hours. If you’re someone who always rolls onto your side, even one night of back-sleeping during that critical first stretch helps.
Keeping Perspective on Aftercare
It’s worth noting that most of these precautions are about optimizing your results, not preventing something dangerous. As one Cleveland Clinic plastic surgeon has pointed out, the majority of unwanted Botox outcomes come from injection technique, not from anything the patient did afterward. If you accidentally bent over to tie your shoes an hour after treatment or forgot and slept on your side, the odds of a significant problem are low.
That said, the precautions are easy enough to follow for 24 hours, and they give the toxin the best chance to settle exactly where your injector placed it. The payoff is results that look more even, last longer, and kick in the way you expected.
