Botox
An injection that temporarily weakens specific facial muscles, so the lines those muscles make soften. It wears off in about three to four months. It does not fill, lift, or improve the quality of the skin.
Key facts
Treats
Movement-related facial lines
Recovery
Brief bumps; bruising possible
Treatment plan
Repeat about every 3–4 months
Typical cost
About $300–600 per area
What is it?
It is a botulinum toxin.
Botox is the brand name for onabotulinumtoxinA, given by a trained clinician.
It relaxes selected muscles.
Its effect on muscle activity is temporary.
It is not a filler.
It does not add volume.
Health history matters.
Neuromuscular disease, swallowing problems, pregnancy and previous toxin treatment should be discussed.

How it works
Diagram explanation
Placed near nerve endings: A clinician injects botulinum toxin into selected muscles. Reduces signal release: The treated nerve ending releases less acetylcholine. Muscle activity relaxes: Movement-related lines can soften as contraction decreases.

Types
Several brands of botulinum toxin are approved in the United States. They work the same way, relaxing the muscles that cause movement lines, but differ in how quickly they start, how far they spread and how long they last.

Before your treatment
2–4 weeks before
Planning: Timing: Allow at least 2 weeks before an important event; results settle in 10–14 days and bruises may last a week.
The week before
Preparation: Medicines and alcohol: Ask about fish oil, vitamin E and ibuprofen; avoid alcohol for 24 hours.
A few days before: Bruising and alcohol: Never stop a prescribed blood thinner on your own.
Day of treatment
Before you arrive
What to bring: Arrive with a clean face, reference photos and clear treatment goals.
Arrival & prep
You say what bothers you while the injector watches your face move.
Treatment
The skin is cleaned, then small injections go into the chosen muscles, a few in each area.
The visit runs 10 to 20 minutes. Each point is a sharp sting, then it is over — most people rate it below a blood test. The forehead and between the brows are the most sensitive.
Before you leave
Small raised bumps like insect bites settle within about 20 to 30 minutes.
After your treatment
First 24 hours
Days 1 to 3: A few people bruise, usually near the eyes.
Days 2–7
Days 3 to 5: Movement feels different — heavy, or a muscle that will not quite fire.
Days 10 to 14: The true result.
Time to results
Starts in 3–5 days, full at 2 weeks
How long results last
3–4 months
Risks
Most side effects come from the needle rather than the medicine — bumps, bruises, a headache for a day or two. The ones that matter come from the medicine reaching a muscle a few millimeters from the target. Those are uncommon and cannot be reversed; there is no antidote, so they wear off over weeks.
A droopy upper eyelid
The lid sits lower and the eye looks smaller or tired, because the medicine reached the muscle that lifts the lid. Uncommon, settles over about 3 to 6 weeks, and prescription eye drops help a little meanwhile.
A heavy or dropped brow
Different from a droopy lid — this comes from relaxing the forehead muscle that holds the brow up. It looks tired and hooded and takes weeks to lift, and is more likely if you already use your forehead to hold your brows up.
Unevenness
One brow higher, or a smile pulling differently on one side. Often correctable with a few extra units once the result has settled at two weeks.
A headache or a flu-like day or two
Common early and self-limiting.
A lump or bruise that is not settling
Worth a look rather than a wait.
Dry, gritty eyes or double vision
Report it, particularly after crow's feet or brow treatment.
Cost
Typical cost
About $300–600 per area
Pricing
In the US it is priced per unit or per area.
Insurance
Insurance does not cover cosmetic use.
Alternatives
Dermal filler
For a different problem. Adds volume where fat and bone have been lost, and softens folds that are there at rest. It does nothing to movement lines, which is why the two are often used together rather than chosen between.
Topical retinoid
On a different target. Improves skin quality, fine surface lines and pigment over months of daily use, for a fraction of the cost. It has no effect on the muscles, so it will not change a frown line.
Fractional laser resurfacing
For texture and etched lines. It rebuilds the skin rather than relaxing the muscle, so it reaches lines that are visible at rest. More cost, real downtime, and more care needed on deeper skin tones.
Surgical brow lift
Permanent. For a heavy, dropped brow, surgery does what an injection cannot. It is surgery, with the recovery and the irreversibility that implies.
Needle-free peptide creams
Sold as an alternative to injections, they cannot reach the nerve endings that matter from the skin surface. Some improve the look of fine lines by hydrating, which is not the same mechanism.
Daily sunscreen, SPF 30 or higher
Does not touch movement lines, but it is the single thing that most changes how skin ages. Anyone paying for injections and skipping this has the order wrong.
Topical retinoid, over the counter or prescription
Improves fine lines, texture and pigment over three to six months of nightly use. It works on the skin, not the muscle, so it is a companion rather than a substitute.
Silicone or hydrocolloid patches worn overnight
Physically hold the skin flat while you sleep. There is some support for the idea, mostly short-term, and any change is temporary and modest.
Peptide creams marketed as needle-free relaxers
Sold on the promise of the same mechanism through the skin. The molecules are too large to reach the nerve ending in a meaningful amount, and the measured effects are small.
Questions
How long does it last?
Three to four months for most people and areas. The jaw muscle and underarm sweating last longer. Fading is gradual, so movement returns over a few weeks.
Does it hurt?
A sharp sting for a second or two per injection, several times. Most people find it easier than expected and skip numbing.
Will I look frozen?
Only if the dose says so. Amount and placement decide how much movement you keep, and a lighter dose at a first appointment is reasonable. You can add more at two weeks; you cannot take any away.
What if I do not like the result?
There is no antidote, so it has to wear off over weeks to a few months. Some problems can be balanced with a few extra units elsewhere, which is why starting conservatively is safer.
Is it safe long-term?
Decades of medical use at doses far larger than cosmetic ones, with no pattern of lasting harm. The main reported change is treated muscles getting somewhat weaker over years, which is the intended effect.
How many units do I need?
That depends on the muscle and the face, not a standard number. As a rough reference, frown lines between the brows are commonly treated with about 20 units of one common brand. Units are not comparable between brands, so ask which product is used.
