Preparing for Botox starts about two weeks before your appointment and comes down to a few straightforward steps: avoid anything that thins your blood, time the appointment well if you have an event coming up, and arrive with a clean face. Most of the prep work is about reducing your chance of bruising and making sure the results settle evenly.
Stop Blood Thinners and Certain Supplements Early
The single most important thing you can do before Botox is cut out anything that thins your blood, ideally starting about two weeks before your appointment. Blood thinners increase bruising at the injection sites, and because the face bruises visibly, even minor bleeding under the skin can leave marks that take a week or more to fade.
The list of what to pause includes over-the-counter painkillers like aspirin and ibuprofen, as well as supplements that have a blood-thinning effect: fish oil, vitamin E, ginkgo biloba, and high-dose garlic. If you need pain relief during this window, acetaminophen (Tylenol) is generally the safer choice because it doesn’t affect clotting the same way. Stanford Medicine’s pre-treatment guidelines specifically note that patients who frequently use NSAIDs bruise more after cosmetic injectables.
If you take a prescription blood thinner for a heart condition or clotting disorder, do not stop it on your own. Talk to the prescribing doctor first. The cosmetic benefit of less bruising is never worth the medical risk of skipping a prescribed anticoagulant.
Skip Alcohol for at Least 24 to 48 Hours
Alcohol dilates blood vessels and has a mild blood-thinning effect, both of which increase the likelihood of bruising. Most providers recommend avoiding alcohol for at least 24 hours before your appointment, though 48 hours gives you a wider safety margin. This applies to wine, beer, and spirits equally. One drink the night before probably won’t cause a dramatic difference, but if you bruise easily in general, the extra caution pays off.
Time Your Appointment Around Events
Botox doesn’t produce instant results. You may notice subtle changes within a few days, but full results typically appear one to two weeks after injection. If you’re getting Botox before a wedding, photo shoot, or other occasion, schedule it two to four weeks ahead. That window lets the treatment take full effect and gives time for any minor swelling or redness to resolve completely.
First-time patients benefit from the longer end of that range. Four weeks gives you a chance to see how your body responds and leaves room for a small touch-up if needed. Returning patients who know their results are predictable can comfortably book two weeks out.
Share Your Full Medical History
Your provider needs to know about certain health conditions before injecting. Neuromuscular disorders like myasthenia gravis are a key contraindication, as Botox works by temporarily blocking nerve signals to muscles, and these conditions already impair that communication. Northwestern Medicine’s Botox checklist flags this as something to disclose immediately.
You should also mention if you’re pregnant, planning to become pregnant, or breastfeeding. The FDA notes that it is not known whether Botox can harm an unborn baby or pass into breast milk, so most providers will not treat you during pregnancy or nursing. Other things worth mentioning: any previous allergic reactions to botulinum toxin products, active skin infections near the treatment area, and any recent vaccinations. Some dermatologists suggest waiting about two weeks after a vaccination before getting Botox, since your immune system may still be reacting and you want to avoid confusing side effects from one with the other.
Avoid Intense Exercise the Day Of
Skip your morning workout on injection day. Vigorous exercise increases blood flow throughout your body, including your face, which can worsen bruising at injection sites. More importantly, elevated blood flow in the hours right after treatment can cause the Botox to migrate away from the targeted muscles, potentially affecting your results or causing unintended weakness in nearby areas.
Most providers recommend waiting at least 24 hours before returning to strenuous exercise. In the first four hours after your appointment, stick with gentle walking and stay upright. Avoid bending over, lying flat, or doing anything that sends a rush of blood to your face. The first 48 hours are the critical window for how well the treatment settles into the right muscles.
Arrive With a Clean Face
Come to your appointment with minimal or no makeup on the treatment areas. Your provider will need to clean the skin thoroughly before injecting to reduce infection risk, and a bare face makes that process faster and more effective. If you’re coming straight from work or running errands, your provider’s office can clean your skin there, but arriving without foundation, concealer, or heavy moisturizer in the injection zones saves time.
It’s also worth pausing retinoids and strong exfoliating acids (like glycolic or salicylic acid products) on the treatment area for a day or two beforehand. These can make skin more sensitive and slightly more prone to irritation at injection sites.
Know What to Expect for Pain
Botox needles are very fine, and most people describe the sensation as a quick pinch rather than real pain. On a 0-to-10 discomfort scale, patients in one clinical study rated Botox injections around a 4.5 without any numbing and about a 3.1 with a topical cooling spray applied beforehand. That’s a meaningful difference if you’re nervous about discomfort.
Many offices apply ice or a topical numbing cream before injecting. If pain is a concern for you, ask your provider ahead of time whether they offer a numbing option so it can be ready when you arrive. These don’t interfere with how the Botox works.
Bruise Prevention Supplements
Some patients take arnica (an herbal supplement available as tablets or topical gel) in the days surrounding their appointment to reduce bruising. Bromelain, an enzyme found in pineapple, is another popular option. Published data in the Journal of Clinical and Aesthetic Dermatology suggests that topical arnica, bromelain, and high-dose vitamin K can reduce bruise formation and speed up healing, though the evidence isn’t strong enough for all dermatologists to recommend them routinely.
If you want to try arnica, most patients start it a few days before the appointment and continue for a few days after. It’s available at most pharmacies and health food stores. It won’t guarantee a bruise-free experience, but it’s low risk and may help, especially if you tend to bruise easily.
Quick Prep Checklist
- Two weeks before: Stop aspirin, ibuprofen, fish oil, vitamin E, and other blood-thinning supplements (unless prescribed by a doctor).
- Two to four weeks before an event: Schedule the appointment, leaning toward four weeks if it’s your first time.
- 48 hours before: Stop drinking alcohol.
- One to two days before: Pause retinoids and strong exfoliants on treatment areas.
- Day of: Skip intense exercise, arrive with a clean face, and eat a normal meal so you’re comfortable during the appointment.
