How Long Does Botox Bruising Last? Why It Happens and What to Do
Injectables · Botox aftercare
A small bruise is the most common thing people notice after Botox. Here’s how long it lasts, why it happens, why some areas bruise more, and when a bruise that won’t fade needs a second look.
How long does Botox bruising last?
Here is the honest answer: there is no official number of days. The BOTOX Cosmetic prescribing information lists bruising as a possible reaction to the injection, and says reactions generally appear within the first week, but it does not give a healing time. Allergan’s own patient pages don’t either. A Botox bruise is an ordinary small bruise, and how long it lasts depends mostly on how big it is.
A pinpoint bruise at one injection point moves through the usual colours, pinkish-red, then bluish, then greenish-yellow, before it fades back to your skin tone, and a small one clears far faster than a larger one. For a sense of scale: in a 2026 study of 152 people treated for crow’s feet, two of 304 treated sides had a small bruise, and no bruising remained at the 10-day check.
| What you see | What it usually means |
|---|---|
| A small red or purple dot at one injection point | A nicked capillary. Common and harmless. |
| A bruise changing from blue to green or yellow | Normal healing. The colour change means it’s on its way out. |
| A bruise still clearly visible after about a week, or getting larger | Call your injector and have it checked. |
| A firm, growing, very painful lump, fever or spreading redness | Contact your provider promptly. These aren’t typical of a simple bruise. |
Why Botox causes bruising
A bruise forms when small blood vessels break and leak into the tissue under the skin. With Botox, the cause is the needle, not the medicine. Each injection passes through skin full of tiny vessels, and now and then the needle nicks one. The prescribing information lists localized pain, swelling, redness and bleeding or bruising as reactions that may be associated with the injection itself, and the American Society of Plastic Surgeons lists bruising at the injection site among the usual side effects.
The clearest evidence that it is the needle: a meta-analysis of 32 placebo-controlled trials covering 9,669 patients found that injection-site bruising happened at similar rates whether people received Botox-type toxin or a placebo injection. A bruise is not a sign the product was wrong or that it won’t work.
Why the forehead, frown lines and crow’s feet bruise more
- Forehead and frown lines. The label dose uses five injection points between the brows and five across the forehead. Each one is another chance to meet a small vessel, so a bruise here often shows as a small purple dot or a faint shadow above the brow.
- Crow’s feet. Three points beside each eye, in thin skin where small veins are often visible, so even a tiny bleed shows easily. The study above was designed around this area for exactly that reason.
- You. People who bruise easily, and anyone taking aspirin, another blood thinner or certain supplements, are more likely to bruise wherever they’re injected.
“Why do I still have a bruise weeks after Botox?”
A simple injection bruise fades. If a mark is still there weeks later, keeps growing, or appeared without an obvious injection point, it is worth having looked at rather than waiting it out, because it may not be a simple bruise. MedlinePlus advises seeing a provider if you’re bruising without a clear cause or have signs of infection. Your clinic would rather see you than have you wonder.
How to lower your chances of bruising
- Tell your injector about every medicine and supplement. The BOTOX Cosmetic medication guide specifically asks whether you take anti-platelets (aspirin-like products) or anticoagulants (blood thinners).
- Pause optional products, if your doctor agrees. A consensus paper on facial injections suggests avoiding nonessential over-the-counter medicines and supplements that affect clotting, such as fish oil and vitamin E, for about a week before treatment. Never stop a prescribed blood thinner without talking to the doctor who prescribed it.
- Ice. The same paper notes that icing may help prevent or minimise bruising because it constricts blood vessels.
- Plan around events. Book Botox at least two weeks before a wedding or photos. That leaves time for any bruise to fade, and Allergan puts full results for the upper face at about 30 days.
What to do if you bruise after Botox
- Cold, gently. MedlinePlus recommends ice wrapped in a clean cloth, never directly on the skin, for up to 15 minutes at a time. Hold it lightly.
- Don’t rub or massage the area. ASPS warns that rubbing treated areas can move the toxin to nearby muscles and cause temporary drooping.
- Cover it. A colour-correcting concealer is fine once the injection points have closed. See skincare after Botox and filler.
- Arnica? The evidence is thin for injections. In one randomized trial of standard bruises made with a laser on the arm, topical 20% arnica improved them more than plain petrolatum over two weeks. It hasn’t been well studied after Botox.
- A stubborn bruise before a big day? A study of a 595 nm pulsed-dye laser on bruises after facial cosmetic procedures reported faster clearing within days. Ask your clinic whether a vascular laser is an option.
Does a bruise mean the Botox won’t work?
No. A bruise is a little blood under the skin and doesn’t stop the medicine from working on the muscle. The label describes the effect starting one to two days after injection and building through the first week. For prices by clinic, see Botox Cosmetic at BHRC.

Frequently asked questions
How long does Botox bruising last?
There is no fixed number of days in the Botox label or from Allergan. A small injection bruise fades through the usual colour changes, and a pinpoint one clears much faster than a larger one. In one study of crow’s feet treatment, no bruising remained at the 10-day check. If a bruise is still clearly visible after about a week, or is getting larger, call your injector.
Is it normal to bruise after Botox?
Yes. The BOTOX Cosmetic label lists bleeding and bruising among the reactions that can come from the injection itself, and trials found bruising at similar rates with placebo injections. Most bruises are small and fade on their own.
Why did I bruise on my forehead after Botox?
The forehead and frown lines take several injection points, and the needle can nick a small blood vessel at any of them. It doesn’t mean the Botox was placed wrongly.
Why do I bruise after Botox around my eyes?
The skin beside the eyes is thin and small veins are often visible there, so even a tiny bleed from a crow’s feet injection shows easily.
Can a bruise from Botox be permanent?
A simple injection bruise is temporary. A mark that is still there weeks later, keeps growing or appeared without a clear injection point should be examined by your provider, because it may not be a simple bruise.
Why do I bruise after Botox when my friend doesn’t?
Skin thickness, how visible your small veins are, the number of injection points and medicines or supplements that thin the blood all make a difference.
Can I put ice on a Botox bruise?
Yes, gently. Wrap the ice in a cloth and hold it lightly for up to 15 minutes at a time. Don’t rub or massage treated areas.
How can I avoid bruising from Botox?
Tell your injector about every medicine and supplement. Ask your doctor whether nonessential products that affect clotting, such as fish oil and vitamin E, can be paused for about a week beforehand, use ice, and book at least two weeks before any big event.
Does a bruise affect my Botox results?
No. A bruise is blood under the skin and doesn’t stop Botox from relaxing the muscle.
When should I worry about a bruise after Botox?
Call your provider if a bruise grows, becomes a firm, painful lump, comes with fever or spreading redness, or is still clearly visible after about a week. Get urgent help for trouble swallowing, breathing or speaking, or double vision.
