Results start in one to two days and build through the first week. Here's the sourced timeline, plus which aftercare rules come from published guidance and which are practice convention.
Direct answer: according to the FDA prescribing information, BOTOX Cosmetic typically begins working one to two days after injection and increases in intensity through the first week. The American Academy of Dermatology reports that most people return to everyday activities immediately, can apply makeup as soon as they leave the treatment room, and should wait two hours before strenuous physical activity. Effects generally last about three to four months.
If you have just booked a first appointment in Bentonville, the two weeks after are more predictable than the internet suggests. Here is what published guidance says — and, just as usefully, which aftercare rules circulating online are practice convention rather than directions stated in that published guidance.
The timeline, hour by hour and week by week
The first two hours
The AAD reports that most people return to everyday activities immediately after treatment and that you can apply makeup as soon as you leave the treatment room. The clear time-bound restriction in its patient guidance is strenuous physical activity: wait two hours. That includes lifting heavy items, working out, and activity that raises your heart rate. The AAD also advises not rubbing or massaging treated areas or pressing or rubbing makeup into them.
Days one to two
This is when the FDA label says you may start noticing an effect. The prescribing information states that initial doses typically induce chemical denervation of the injected muscles one to two days after injection. Seeing little at 48 hours does not by itself mean that treatment has failed; it is the early edge of the expected window.
Days three to seven
The FDA label describes the effect as increasing in intensity during the first week. This is the period when most visible change occurs.
Weeks one to two
By the end of this window, you are generally looking at the settled result. This is a practical time for a follow-up assessment if a practice offers one and for raising a cosmetic concern such as asymmetry. Ask about follow-up policy before booking so you understand the practice's process.
Months three to four
The AAD states that the effect lasts about three to four months — and sometimes longer. The FDA label describes an approximate three- to four-month duration for glabellar lines. The AAD also notes that repeat treatment for lines and wrinkles may thin the muscle, which can lead to longer-lasting results over time.
Which aftercare rules are actually sourced
What published guidance says: wait two hours before strenuous activity, do not rub or massage treated areas, and makeup is fine immediately if you do not press or rub it in. Those points come from the AAD's patient guidance.
What the AAD and FDA label do not specify: you may encounter instructions to stay upright for four hours, avoid alcohol for 24 hours, skip facials for two weeks, avoid saunas, or sleep on your back. These are common clinical conventions. They may reflect reasonable caution about migration, bruising risk, or blood flow, but published AAD patient guidance and the FDA label do not set those exact rules.
That does not make a clinician's stricter instructions wrong. Your treating clinician knows your anatomy, product, and injection pattern. Follow the specific instructions from the person who treated you, and ask why a particular instruction is being given if you want context.
What's normal, and what warrants a call
The AAD lists swelling, redness, soreness, bruising, mild headache, and, rarely, temporary drooping of a brow or eyelid among reported effects. The FDA prescribing information carries a boxed warning about distant spread of toxin effect. Listed symptoms include generalized muscle weakness, double vision, drooping eyelid, difficulty swallowing, voice or speech difficulty, urinary incontinence, and breathing difficulties.
The timing detail matters. The FDA label says these symptoms have been reported hours to weeks after injection. Swallowing and breathing difficulties can be life-threatening and warrant immediate medical care. Your treating clinician is the appropriate person to discuss contraindications, medications, pregnancy or breastfeeding questions, and neuromuscular history.
One note on where you get treated
The AAD advises against getting botulinum toxin injections at a non-medical spa, party, salon, or someone's home. Its distinction is medical oversight — not the word “spa” on the door. Aftercare is one place that distinction becomes practical: you should know a practice's after-hours contact procedure before treatment.

Frequently asked questions
How long after Botox will I see results?
One to two days for the first signs, with the effect increasing through the first week. The FDA prescribing information states that initial doses typically induce chemical denervation one to two days after injection, increasing in intensity during the first week. Assess a settled result at around two weeks.
How long should I wait to work out after Botox?
AAD's patient guidance says two hours. Some practices give a longer restriction based on their own protocol; follow the instruction your clinician gave you.
Can I wear makeup after Botox?
Yes. AAD states you can apply makeup as soon as you leave the treatment room, while cautioning against pressing or rubbing it into treated areas.
When should I call my provider after Botox?
Seek immediate care for swallowing, speech, or breathing difficulty, or generalized muscle weakness. For cosmetic concerns such as asymmetry, contact your clinician according to its follow-up guidance; a two-week assessment is a common practical checkpoint while results settle.
How soon can I get Botox again?
Generally when the effect wears off, around three to four months. Your clinician should set your specific interval.
